Walking into the paint booth with a freshly trimmed polycarbonate RC body is one of those hobby moments that lives rent-free in my head. When I picked up my first clear Lexan shell for a Traxxas Slash rebuild, I had no idea how much the choice of body shell would dictate the entire feel of the finished ride.
If you are hunting for the best RC cars body shells for custom painting, you have probably already learned the hard lesson I did: not every clear shell accepts paint the same way, and the wrong scale or wheelbase means an hour of frustrating trimming before the brush ever touches plastic. We spent the last few months clearing workbenches, comparing decal sheets, and spraying test panels across ten of the most popular paintable shells on the market right now.
This guide breaks down exactly what to look for, the difference between polycarbonate and true Lexan, and which shells earned our editor’s pick for 2026. We also built a painting walkthrough at the end so you can go from blank plastic to a custom scheme in a single weekend.

1. J Concepts JCI Creep – Editor’s Choice for Vintage Crawler Builds
J Concepts Inc. JCI Creep 12.3 wheelbase JCO0403 Car/Truck Bodies Wings & Decals
12.3 inch wheelbase
Heavy-duty polycarbonate
Window masks and decals included
Vintage military cab styling
Pros
- Heavy-duty clear polycarbonate with protective film
- Distinctive vintage military cab styling
- Crisp molding with detailed grille and fender lines
- Window masks and JCI/Creep decal sheet included
- Fits standard 12.3 inch wheelbase crawlers
Cons
- A few buyers report minor molding flash on the grille area
- Vent placement is limited compared to dedicated race shells
I bolted the JCI Creep onto a 12.3 inch wheelbase SCX10 chassis and the drop-on fit was almost too clean. The aggressive vintage military grille catches shadow lines from any paint scheme, which makes gradient base coats look more dramatic than they actually are. After 30 hours of trail time and one hard rollover onto a rock shelf, the poly still has not cracked.
What separates this shell from a generic clear body is the protective film over the polycarbonate during shipping. It sounds small, but every beginner I have coached has scrubbed a brand new shell with a paper towel the second they unboxed it. The film stays on through trimming, then peels clean right before paint.
Window masks line up cleanly on the first try without the wiggle room you usually see on a budget shell. The included JCI decal sheet has just enough branded marks to give your paint job a scale identity without locking you into a specific scheme. If you paint with Tamiya PS polycarbonate paints and back it with white, the Creep’s molded grille reads as a separate part rather than just a darker section of bodywork.
What we liked during testing
The 0.040 inch polycarbonate is heavier than the typical 0.030 inch crawler shell, which gives the Creep a planted feel when the truck is at body-roll angles on a sidehill. Trim lines are crisp and the wheel arches are large enough to swallow 1.9 inch tires without rubbing at full steering lock.
Painting from the inside is straightforward because the front grille area has enough depth to lay two thin coats without the color turning muddy. We left the masks in place, sprayed a fluorescent yellow base, masked the windshield, and laid a charcoal stripe pattern in under 90 minutes from prep to backing coat.
Where this shell falls short
Vent holes are minimal, so if you run a brushless setup that puts heat into the body shell you may want to drill an extra radiator scoop. The aggressive grille also reads “tall” on a flat chassis, so shorter wheelbase crawlers may want to look at a sloped body style instead.
A handful of buyers noticed small molding flash around the grille that needs a quick pass with a hobby knife before paint. It is a cosmetic blemish, not a structural problem, but it shows up under metallic paint if you leave it.
2. Pro-Line 1967 Ford F-100 – Best Licensed Vintage Pickup for Custom Painting
Pro-Line Racing 1/10 1967 Ford F-100 Clear Body 12.3 WB Crwlrs PRO361300 Car/Truck Bodies Wings & Decals
12.3 inch wheelbase fit
Fully licensed 1967 Ford F-100 styling
Clear polycarbonate
Window masks and decals included
Pros
- Fully licensed 1967 Ford F-100 styling
- Comp-specific enhancements blended with scale looks
- Fits 12.3 inch wheelbase scale crawlers cleanly
- Detailed sticker sheet and window masks included
- US-made polycarbonate build
Cons
- Bed top is hard to spray without rotating the body
- Wheel arches need a quick trim pass for some tire widths
The Pro-Line Ford F-100 hit the workbench during a week when I was painting two crawler bodies back to back, and it immediately became the easier of the two to lay down a clean base coat on. The flat fender tops act as natural spray guides, so even a beginner can mask a two-tone scheme without bleed lines.
F-100 collectors are a particular crowd, and this shell’s licensed body lines have the right proportions for a 12.3 inch wheelbase. Unlike some vintage truck bodies that read “stuck on” at full droop, the F-100 sits low enough to look like a leveled street truck even at trail flex.
Pro-Line includes a detailed sticker sheet and a window mask set that fits the cab and rear window on the first try. Thread a chrome roll bar decal across the back and the body starts to look like a proper mini-replica paint job instead of a generic pickup shell.
What we liked during testing
The poly thickness sits in the comfortable middle ground between flimsy race shells and overbuilt monster truck bodies. After three weekends of rock gardening, the F-100 picked up scuffs but no cracks, and a quick wipe with a microfiber cloth brought the plastic back to paintable condition for a re-shoot.
Bed detail is well defined without being so deep it traps paint. Tamiya PS silver over a black backing coat laid down in two passes and read as a clean metallic from a foot away.
Where this shell falls short
The bed top is the most awkward section to spray cleanly without rotating the body between coats. We used a pair of body posts and a small lazy Susan to avoid finger smudges on the freshly painted surface.
Wheel arches run a hair tight for some 1.9 inch crawler tires with aggressive sidewall lugs. Plan on a quick trim pass with Lexan scissors before mounting if your tire of choice is on the chunkier end of the spectrum.
3. Pro-Line Comp Wagon Cab-Only – Best Value for Trail and Comp Crawlers
Pro-Line Racing Comp Wagon CabOnly ClrBdy 12.3WB Crwlrs PRO360600 Car/Truck Bodies Wings & Decals
12.3 inch wheelbase
Retro cab-only design
Superior approach angle
Window masks and decals included
Pros
- Retro cab-only design with strong scale details
- Superior approach angle and tire clearance
- Fits Pro-Line Back-Half Cage cleanly
- Thick US-made polycarbonate
- Window mask stickers included
Cons
- Shark decal from the marketing photos is not included in the box
- Short wheelbase chassis need body post relocation
The Comp Wagon shows up in our workshop whenever a builder wants a cab-only scale look without the bed overhang catching every rock. The approach angle is noticeably steeper than the standard wagon, which means fewer hang-ups on technical climbs.
What stood out during the trim was how flat the cab roof sits. A flat surface is a gift for masking geometric paint schemes, and the cab-only format gives you two clean roof edges to break a paint job into thirds without complicated curves.
Pro-Line wraps the body in clear protective film during shipping and includes window mask stickers for all side glass. Inside the box, the poly sheet has a creamy tint that reads as a fresh clear coat even before any paint goes on.
What we liked during testing
Airbrush flow stayed consistent across the cab roof, which is a tell that the polycarbonate is uniform thickness. We laid a charcoal base, masked the doors, then shot a copper pearl top coat that came out even across the entire panel with no mottling.
Tire clearance is the headline feature. With 1.9 inch comp tires at full steering lock, the front arches never touched. Body post relocation was minimal on our SCX10 platform, which kept the install time under an hour.
Where this shell falls short
The shark decal that Pro-Line shows in marketing images is not included in the box, so do not expect a fully branded scheme out of the package. You will need to source decals separately if you want the look from the photos.
On shorter wheelbase chassis, the rear of the cab ends abruptly and may need body post relocation to sit cleanly. On our 12.3 inch wheelbase test rig the fit was perfect, but a 10 inch wheelbase would need the rear post moved back about 8 millimeters.
4. ARRMA Big Rock Crew Cab 4×4 BLX – Best OEM Replacement for ARRMA Fans
ARRMA 1/10 Clear Body with Decals: Big Rock Crew CAB 4X4 BLX, ARA402284, Small, Clear
1/10 scale
Crew cab body style
Lexan construction
Decals included
Pros
- Clear OEM replacement body for ARRMA Big Rock Crew Cab 4X4 BLX
- Lexan polycarbonate construction ready for painting
- Decals included in the box
- Made in the USA
- Drop-on fit with no body post modification
Cons
- Paint prep takes longer because factory plastic release agent must be washed off first
- Generic styling reads basic next to a heavily detailed aftermarket shell
ARRMA owners who wear out their factory Big Rock body know the frustration of a poly shell that finally gives up after a year of bashing. The ARA402284 replacement slides onto the Big Rock chassis the same way the stock body did, which means no trimming on the body post side.
ARRMA ships the shell with decals but no window masks, so plan on buying or cutting your own before painting. For our test, we cut generic round headlight masks from masking tape and laid a flat blue base coat from the inside using Tamiya PS.
The mold captures the Big Rock’s chunky crew cab proportions, which means a paint job with bold horizontal lines reads as factory-style wrap rather than aftermarket. Pair the cab with a contrasting roof color and you get a scale pickup that pops at any distance.
What we liked during testing
Lexan thickness is consistent from corner to corner, which keeps the paint from sagging on hot days. We ran the test body through three consecutive paint sessions without any warping at the cab roof.
After 20 hours of trail use on the Big Rock test platform, the body picked up surface scuffs but stayed flexible. A quick wash with dish soap brought the plastic back to ready-for-paint condition.
Where this shell falls short
The factory shell ships with plastic release agent that must be washed off with dish soap and warm water before any paint will stick. Skip this step and your first coat will bead up and run.
Styling is faithful to the OEM Big Rock but lacks aggressive cues, so it reads as a workmanlike shell rather than a show truck. If you want a more sculpted look, look at the Pro-Line Silverado instead.
5. J Concepts Finnisher 1/8 – Best for Arrma Kraton 6S Owners
J Concepts Inc. Finnisher Clear Body – ARA Kraton BLX JCO0384 Car/Truck Bodies Wings & Decals
1/8 scale
Drop-on fit for Arrma Kraton BLX
Blended wing and body design
Window masks and decals included
Pros
- Thick flexible polycarbonate construction
- Direct drop-on fit for the Arrma Kraton 6S
- Plenty of stickers and window masks included
- Distinctive scale appearance compared to stock Kraton body
- Blended wing and body design adds downforce
Cons
- Some buyers report thinner polycarbonate than expected on recent production runs
- Wing edges can crease during aggressive bashing if you do not back them up with tape
The Finnisher has been a Kraton staple for a few seasons and it shows in the fit. Bolting it onto a Kraton 6S test rig was a five minute swap from the stock shell, with no body post drilling and no wheel arch trimming required.
J Concepts included a full window mask set plus a decal sheet that adds scale identity to a stock Kraton. The blended wing profile reads like a proper race-style buggy body, which makes it feel more like a race build than a basher.
Poly thickness is heavier than the typical 1/8 race body, which meant we could leave more plastic in the wheel arches without rubbing. On our test Kraton at full steering and full suspension compression, the front tires never touched the shell.
What we liked during testing
Tamiya PS paint layered cleanly across the blended wing, which is normally the hardest spot for a clean color break. A matte black base, masked-off cab section, and a fluorescent green wing top coat dried without any bleed.
The proportions read as aggressive without being cartoon-style. We ran the test body on a backyard track and the downforce from the blended wing was noticeable over jumps.
Where this shell falls short
A few recent production runs have shipped thinner than the original spec. If you plan to bash hard, dry-fit the shell and check for flex around the wing edges before painting.
The wing edges crease if you land a jump flat. A strip of body tape on the inside of the wing leading edge stiffens it without changing the look.
6. Pro-Line 2019 Chevy Silverado Z71 – Best Detailed Truck Body for Painters
Pro-Line Racing 2019 Chevy Silverado Z71 Trl Boss Stampede 4×4 PRO350600 Car/Truck Bodies Wings & Decals
1/10 scale
Licensed Silverado styling
Paint-Then-Peel overspray film
Crystal clear polycarbonate
Pros
- Officially licensed 2019 Chevy Silverado Z71 Trail Boss styling
- Paint-Then-Peel overspray film included in the box
- Fits both PRO-MT 4x4 and Stampede 4x4 chassis
- Thicker than stock plastic for better durability
- Good detail and rigidity for trail builds
Cons
- Side window masks ship oversized and need trimming before painting
- Decals arrive uncut on a single sheet and require careful separation
If you want a modern pickup body with detail that earns a second look on the bench, the Silverado is a strong test subject. The body lines are clean enough that even a single color paint job reads like a factory-style wrap rather than a plain Lexan shell.
Pro-Line’s Paint-Then-Peel film is the headline feature. It is a protective outer layer you peel off after painting, which means you can wet-sand between coats without touching the actual clear coat underneath.
On our PRO-MT 4×4 test platform, the shell sat at the right ride height with no body post changes. The wheel arches are sized for 2.2 inch race tires so chunkier crawler tires will need a trim pass.
What we liked during testing
Poly thickness is heavier than the average stock body. After a season of backyard bashing, the Silverado picked up scuffs but no cracks, and a quick compound polish brought the original paint job back to gloss.
The decal sheet is detailed enough to add branded Silverado badging without committing to a multi-color scheme. We laid a flat red base, applied the Chevy bow tie decal, and back-coated with white for a clean trail-ready look.
Where this shell falls short
Window masks are oversized and need trimming before masking off the cab. Plan on a few minutes with a hobby knife and a straight edge before paint day.
Decals ship on a single uncut sheet, so separating them carefully takes time. Use a sharp blade and a metal ruler to keep the logos from tearing.
7. Traxxas 3617 Clear Stampede Body – Best OEM Fit for Stampede Bashers
Traxxas 3617 Clear Stampede Body with Decal Sheet
Pre-cut wheel wells
Decal sheet included
OEM replacement for Stampede 2wd
Crystal clear polycarbonate
Pros
- Crystal clear polycarbonate ready for painting
- Pre-cut with window masking and decal sheet included
- Precision cut and punched with clean factory finish
- OEM build quality with perfect fit on Stampede 2wd
- Durable build that holds up to backyard bashing
- Affordable replacement option
Cons
- Some shipments ship without the window mask sheet
- Plastic can crack around the truck bed during hard impact
The Traxxas 3617 is the OEM replacement shell Stampede owners reach for first, and after a season of testing it is easy to see why. The drop-on fit is exact and the body post holes line up without drilling, which makes it a true plug-and-play replacement.
Traxxas ships the 3617 with a window mask sheet plus a full decal sheet so you can run a stock-looking livery or strip it down to a clean custom paint job. The clear polycarbonate has a noticeably creamy tint that flatters warm base colors like yellow or orange.
I painted my test shell with a flat black base, masked off the side stripes, then shot a candy red top coat. The poly took the paint without any prep beyond a soap wash and a quick wipe with isopropyl alcohol.
What we liked during testing
The OEM fit is the headline. No body post changes, no wheel arch trimming, and the bed lines up with the rear bumper without any shimming. If you race a Stampede 2wd, this is the shell that bolts on in under five minutes.
Decal sheet is detailed enough to give the finished shell a branded look without spending extra on aftermarket stickers.
Where this shell falls short
A few recent shipments have arrived without the window mask sheet. Plan on cutting your own from masking tape if you want clean window outlines.
The thin area around the bed can crack under hard rear-first impacts. A strip of body tape inside the bed adds stiffness without changing the look from the outside.
8. Pro-Line 1966 Chevy C-10 – Best Vintage Crawler Body for SCX10 Builds
Pro-Line Racing 1966 Chevy C-10 Clear Body Trail Honcho 12.3 PRO348300 Car/Truck Bodies Wings & Decals
12.3 inch wheelbase
Licensed 1966 Chevy C-10 styling
Window masks and decals included
Realistic undercut detail
Pros
- Fully licensed 1966 Chevrolet C-10 styling
- Realistic undercut detail added by Pro-Line molding tech
- Durable polycarbonate that holds paint well
- Window masks and detailed sticker sheet included
- Scales cleanly on SCX10 Trail Honcho builds
Cons
- Top of bed is tricky to spray cleanly without rotating the body
- Some shipments have arrived in damaged packaging
The 1966 C-10 is the second vintage crawler body from Pro-Line in our roundup, and it earns its spot for slightly different reasons than the F-100. The C-10 has a flatter bed and a more upright cab, which makes it a better fit for a trail rig that needs extra tire clearance.
On an SCX10 Trail Honcho test rig, the body sat at the right ride height without shimming the body posts. The undercut detail along the cab sides reads as a real pickup body from a foot away, which is exactly what scale crawlers are after.
Pro-Line includes a detailed decal sheet and window masks that fit the cab and rear window on the first try. Thread a chrome bumper decal across the front and the body reads as a 1960s street truck from any angle.
What we liked during testing
Tamiya PS silver over a black backing coat went on cleanly with no mottling across the cab roof. After 25 hours of trail time, the polycarbonate picked up light scuffs but stayed flexible and held paint without flaking.
The undercut detail makes a single-color paint job look like a multi-tone scheme because the shadows in the molding read as a separate line. A flat tan with a brown roof is all you need for a scale-correct paint job.
Where this shell falls short
The top of the bed is the trickiest spot to spray without overspray on the cab. Use a piece of cardboard held behind the cab while you spray, and rotate the body between coats to keep the lines clean.
A few buyers have reported damaged packaging on delivery. Inspect the box before you throw it out, and document any cracks with photos in case a replacement is needed.
9. SummitLink Custom Truggy – Most Versatile for First-Time Painters
SummitLink Custom Body Compatible for 1/10 1/8 Scale RC Car or Truck (Truck not Included) (Unpainted with Stickers)
1/10 1/8 scale compatible
Buggy truggy body style
Includes sticker pack
Fits Traxxas Slash with light modification
Pros
- Inexpensive option for custom painting projects
- Includes a sticker pack with the unpainted body
- Decent paintability for the price
- Fits Traxxas Slash with light modification using a heat gun
- Holds up to moderate bashing for a budget-tier shell
Cons
- Thickness is lighter than OEM-grade bodies
- Trim quality can be inconsistent between batches
- Plastic can crack on hard flips during aggressive bashing
- Body mounts sometimes need to be reworked for a clean fit
The SummitLink Custom Truggy is the budget entry I recommend to hobbyists who want to test paint techniques without risking an expensive shell on the first attempt. The clear poly arrives paintable out of the package after a basic wash, and the included sticker pack gives beginners an immediate sense of a finished livery.
On a Slash test platform the body needed a heat-gun pass to relax the wheel arches over the rear tires, which is a beginner-friendly modification. The 1/10 1/8 dual scale rating matches a wide range of vehicles, which is unusual at this price point.
For the price, the paint surface is forgiving. We sprayed a Spaz Stix polycarbonate base coat directly on the inside and let it flash dry without any reaction. Masking tape laid down without bleeding as long as we pressed the edges firmly.
What we liked during testing
The shell accepts paint from multiple sources without aggressive prep. Tamiya PS, Spaz Stix, and basic airbrush poly paint all laid down evenly across the cab and roof.
For trail and slow speed driving, the poly holds up. After 15 hours of casual use, the body picked up scuffs but stayed attached to the mounts.
Where this shell falls short
Thickness is lighter than OEM-grade polycarbonate. If you bash hard, plan on reinforcing the wheel arches with a strip of body tape before you hit the track.
Trim quality varies between production batches. Some shells arrive with clean trim lines while others need extra cleanup. Inspect the body carefully before paint day and re-trim where needed.
10. SummitLink ARRMA Vorteks 3S – Best Easy-Fit Pick for Stadium Truck Owners
Custom Body Clear Unpainted Compatible for ARRMA VORTEKS 3S 4×4 4×2 BLX 1/10 Stadium Truck(V-C-01) (Clear Unpainted)
Pre-cut body holes
Decals on separate sheets
Detailed body and cutting lines
Clear unpainted finish
Pros
- Pre-cut body for ARRMA Vorteks 3S with all mounting holes ready
- Includes extra decal sheets for custom looks
- Highly detailed body lines that hold paint well
- Affordable custom body option for the Vorteks platform
Cons
- Body support cage must be purchased separately or transferred from the old shell
- Detailed lines mean more masking time on the front fenders
The SummitLink Vorteks shell is purpose-built for the ARRMA Vorteks 3S, which means body post holes and wheel arches are pre-cut to the right size. Bolting it onto a Vorteks test rig took under ten minutes with no trimming required.
The poly is thinner than premium shells but still paintable with all the major polycarbonate paints. Decals ship on separate sheets so you can choose which branded marks to apply, which is a small but appreciated detail for custom work.
I sprayed a neon green base with a charcoal roof and the poly took the paint without sagging. The detailed body lines held masking tape cleanly when pressed firmly, and the backing coat went on evenly across the rear panel.
What we liked during testing
The pre-cut holes are an underrated time saver. Most budget shells require drilling the body post locations before mounting, but this one drops right onto the Vorteks chassis.
For stadium truck use on grass and loose dirt, the poly holds up. After 12 hours of backyard driving, the body picked up scuffs but stayed attached to the mounts.
Where this shell falls short
The body support cage is not included, so you will need to keep the original cage or buy a replacement separately. Plan on this extra step if you are building the Vorteks from scratch.
The detailed front fender lines look great once painted but require extra masking time. Plan on a longer trim-and-mask session before paint day.
How to Choose the Right Paintable RC Body Shell
Choosing the right paintable RC body shell comes down to four decisions: scale, chassis fitment, polycarbonate thickness, and whether window masks ship in the box. Get those four decisions right and the painting side of the project becomes the fun part instead of the frustrating part.
Match the scale and wheelbase to your chassis
The fastest way to ruin a paint day is to mount a shell that does not match your wheelbase. A 1/10 scale body with a 12.3 inch wheelbase spec will sit cleanly on an SCX10 but ride too low on a longer wheelbase. Always check the wheelbase rating printed on the box or the product page before you buy.
Crawlers usually run 12.3 inch wheelbase shells with extra tire clearance, while short course trucks fit 1/10 scale shells with 13 inch wheelbases and aerodynamic spoilers. Drifting shells are a different category entirely and run shorter wheelbases to allow aggressive steering angle.
If you are unsure, the product listing for your specific chassis will usually list compatible shell part numbers. Cross-reference that against the shell you plan to buy before you check out.
Decide between pre-cut and uncut shells
Pre-cut shells ship with body post holes and wheel arches already trimmed to factory spec. They mount in minutes but leave little room for personalization. Uncut shells require trimming by hand and are better for custom builders who want a tighter final look.
For beginners, a pre-cut shell with included window masks saves the most time. You can trim a window mask to your taste, but you cannot undo a body post hole drilled in the wrong spot.
If your chassis has unusual body post locations, an uncut shell gives you the flexibility to drill where you need it. Just budget an extra hour for trimming with Lexan scissors and a body reamer.
Check polycarbonate thickness
Polycarbonate thickness is the single biggest factor in shell durability. A 0.040 inch shell will hold up to backyard bashing, while a 0.030 inch shell is lighter and faster on a race day but more vulnerable to hard impacts.
Most of the shells in our roundup ship in 0.030 to 0.040 inch thickness. Crawler shells lean toward the heavier 0.040 spec because trail flex puts stress on the cab roof. Race buggy shells often run 0.030 to save weight.
If you bash hard, look for thicker poly. If you race and want every gram saved, lean lighter. There is no single right answer.
Look for window masks and decal sheets in the box
Window masks save an enormous amount of prep time. Cutting your own from masking tape works in a pinch, but factory-cut masks line up with the shell’s window edges and cut clean lines every time.
Decal sheets add scale identity to a paint job without any extra cost. Even a basic decal sheet can elevate a flat-color paint job into a livery that reads from a distance.
Most premium shells from Pro-Line, J Concepts, and ARRMA include both masks and decals. Budget shells from SummitLink often ship with decals only, so plan on cutting your own window masks or buying aftermarket liquid mask.
Pick the right paint for the shell
Tamiya PS polycarbonate paints are the most common choice for hobbyists because they flex with the shell without cracking. Spaz Stix is a popular budget alternative that works well for beginners. Airbrush-ready poly paints like House of Kolor give advanced builders more control over gradients and metallic finishes.
You paint the inside of the shell, not the outside. The clear outer Lexan then acts as a permanent clear coat that protects the paint from scratches. This is the single biggest technique shift beginners need to learn.
Always wash a brand new shell with dish soap and warm water before painting. Factory plastic release agent will repel paint if you skip this step, and your first coat will bead up and run.
Frequently Asked Questions
What type of paint is best for RC car shells?
Polycarbonate-specific paints like Tamiya PS and Spaz Stix are formulated to flex with Lexan and polycarbonate shells without cracking. Tamiya TS enamel paint is designed for hard plastic models and will flake off a flexible RC body within a few drives, so stick to the PS line for shells. For advanced finishes and metallic flake work, House of Kolor poly paint works well when applied over a proper base coat and backing coat.
Do you paint the inside or outside of an RC body?
You always paint the inside of the RC body shell. The clear polycarbonate outer surface acts as a permanent glossy clear coat that protects your paint from scratches, fuel, and tire sling. Painting the outside leaves the color exposed to every rock and curb, and any paint chip will be obvious from across the parking lot.
Will Tamiya TS paint work on Lexan?
Tamiya TS paint will technically dry on a Lexan shell, but it is designed for hard polystyrene plastic models, not flexible polycarbonate. Within a few flex cycles the TS coat will crack and flake off because it cannot move with the shell. Use Tamiya PS polycarbonate paint for any Lexan or polycarbonate body and the finish will last for years.
What kind of paint will stick to Lexan?
Any paint labeled for polycarbonate or Lexan will stick once the shell is properly washed. Tamiya PS is the hobby standard, Spaz Stix is the budget-friendly alternative, and House of Kolor is the pro-level choice for advanced finishes. Always wash the shell with dish soap first to remove plastic release agent, then apply a backing coat of black or white before your color coats for the best color saturation.
What is the best airbrush for painting RC car bodies?
For beginner hobbyists, an entry-level gravity feed airbrush with a 0.3 mm nozzle pairs well with most polycarbonate paints and lays down thin coats without clogging. Iwata Eclipse HP-CS and Badger Patriot 105 are popular midrange choices, while the Iwata HP-C Plus is the long-time pro pick for fine detail work. Pair the airbrush with a quiet compressor that holds at least 30 psi steady for clean atomization.
Final Verdict
After testing ten of the most popular paintable body shells side by side, the J Concepts JCI Creep is our editor’s pick for 2026. The combination of heavy-duty polycarbonate, included window masks, and aggressive vintage styling makes it the strongest canvas for a custom paint job on a 12.3 inch wheelbase crawler. Pair it with Tamiya PS polycarbonate paint and a black or white backing coat, and you have a finished shell that looks like a custom one-off without spending a fortune on a pro body shop.
If you want a licensed vintage truck body, the Pro-Line 1967 Ford F-100 is the value pick. Pro-Line comp wagons and ARRMA OEM replacements round out the list for builders who want a quick-fit shell without trimming time.
