RC Car Body Painting Techniques, Tools, and Featured Custom Designs
Contents
The blank, clear shell sits on your workbench – a transparent canvas of possibility. Your Traxxas or Tamiya RC car deserves better than a generic look. But one wrong move with that spray paint can, and weeks of planning vanish in a cloudy, peeling mess, which is a concern often discussed in the RC community. RC body painting mistakes don’t just look bad – they cost time and money.
“The biggest mistake people make is using the wrong paint,” explains Mark Focareta, owner of HobbyTown Santee. “Regular spray paint won’t stick to Lexan bodies. You need specific polycarbonate paint that’s applied to the inside of the body, not the outside.”
This inside-out approach separates RC body painting from nearly every other paint job you’ll ever tackle. The technique might seem backward at first, but the results – a glossy, durable finish that withstands crashes and debris – make the learning curve worthwhile for dedicated hobbyists looking to stand out at the track or on the trail.
Understanding RC Car Bodies: The Canvas
RC car bodies serve as both protective shells and style statements. Made from lexan (polycarbonate), these lightweight, flexible shells withstand impacts that would shatter plastic or crack fiberglass. But this durability comes with unique painting challenges.
“Lexan bodies are painted from the inside,” Focareta emphasizes. “You have to think in reverse. Your first layer of paint is actually what will show on the outside as your top layer.”
This reverse-order approach means planning ahead. For the weekend warrior who spends hours perfecting their RC car setup, this process demands the same attention to detail as suspension tuning or motor selection.
The painting process starts with preparation. Most RC bodies come with a protective film on the outside that stays in place during painting.
“You should wash it with soap and water to remove any oils or residue from manufacturing before beginning the paint application.” says Focareta.
Different RC bodies require specific approaches. A Traxxas Slash truck body with its angular panels presents different challenges than the smooth curves of a buggy shell. Crawler bodies often feature scale details that demand careful masking, while race car bodies prioritize vibrant, visible colors that stand out on the track.
The type of RC car you have matters,” Focareta notes. “Race cars usually have simpler, brighter paint schemes so they’re easier to see at a distance. Scale crawlers often have more detailed, realistic paint jobs with weathering effects.”
Before any paint touches the lexan, planning the design proves vital. The dedicated hobbyist who meticulously researches every aspect of their RC car knows that proper preparation prevents disappointing results. This means collecting the right tools and materials before starting the project.

Essential Tools and Materials
Success with RC body painting demands specific supplies. Regular craft paints won’t adhere to polycarbonate bodies – they peel, flake, and ruin hours of work.
“You absolutely need polycarbonate paint made specifically for lexan,” Focareta stresses. “Tamiya PS spray paints are the standard. They’re designed to stick to the inside of RC bodies and give you that perfect finish.”
The serious RC enthusiast who spends weekends perfecting their custom paint jobs needs these key materials:
- Polycarbonate-specific paints – Tamiya PS (spray cans) provide reliable results for RC car bodies
- Liquid mask – This removable coating protects areas you don’t want painted
- High-quality masking tape – For creating clean lines and blocking larger areas
- Scissors and hobby knife – For cutting masks and templates
- Isopropyl alcohol – For final cleaning before painting
- Microfiber cloths – Lint-free wiping prevents contamination
“The difference between cheap masking tape and good masking tape is huge,” Focareta explains. “Cheap tape lets paint bleed underneath. Good tape gives you those sharp, clean lines that make a custom paint job look professional.”
Spray cans offer simplicity, while airbrushes provide precision for detailed work on truck bodies and scale models. The weekend warrior who values both convenience and quality often starts with spray cans before investing in airbrush equipment.
“An airbrush gives you more control for custom work,” says Focareta. “But for beginners, Tamiya spray cans work great. They spray evenly and come in tons of colors, including metallic finishes and even a matte finish option.”
Step-by-Step RC Body Painting Process
The RC body painting process reverses traditional painting logic. You work from the outermost visible layer inward, applying colors in reverse order, which is crucial for achieving a professional finish in painting rc bodies.
Preparation
The process begins with thorough preparation of your lexan body:
- Keep the protective film on the outside – This clear film protects the exterior during painting, ensuring that your custom painted rc stays pristine.
- Wash thoroughly – Use mild soap and water to remove any oils or residue
- Final cleaning – Wipe with isopropyl alcohol to remove dust and fingerprints

Masking
Masking creates your design by protecting areas from paint:
- Apply liquid mask to areas that will remain clear (windows, light covers)
- Create templates for complex designs using paper or pre-cut mask sets
- Use masking tape for straight lines and larger blocked areas
“Liquid mask is amazing for complex designs,” Focareta explains. “You paint it on like a clear coat, let it dry, then cut along your design lines with a sharp hobby knife. When you’re done painting, you peel it off to reveal perfect clear sections.”
Painting
The painting sequence matters critically for RC car bodies:
- Start with the lightest colors – White, yellow, and other light colors go first
- Apply in thin, even coats – Multiple light coats prevent running and pooling
- Let each color dry completely – Patience prevents smudging and color mixing
- Finish with backing coats – Black, Silver, or white backing makes colors look slightly different
For multi-color designs on RC bodies, each color requires its own masking and painting step:
Backing and Finishing
The final steps seal your design and enhance color vibrancy:
- Remove all masking – Carefully peel away liquid mask and tape
- Remove protective film from the outside
- Trim the body as needed for mounting
“The backing coat is super important,” says Focareta. “Without it, your colors look transparent and weak. White backing makes colors bright and vibrant. Silver or Black backing gives them a slightly different look.”

Advanced Techniques
Experienced RC enthusiasts push beyond basic painting to create truly unique RC car bodies.
Multi-Layer Effects
Creating depth and visual interest requires planning and patience:
Custom airbrush work allows for gradients, fades, and realistic effects impossible with spray cans alone:
“With an airbrush, you can create smoke effects, realistic flames, or gradual color transitions,” explains Focareta. “You can even do weathering effects for scale crawler bodies to make them look like real, used vehicles.”
Special Custom Paint Finishes
Beyond basic colors, specialty finishes create distinctive RC bodies:
- Metallic finishes – Tamiya offers several metallic options for a showroom shine that can elevate your custom painted rc project.
- Fluorescent colors – Ultra-bright options stand out on the track
- Transparent colors – Create candy-like finishes over metallic bases
Decals and Details
The finishing touches often make the difference between good and great RC car bodies:
“Decals add that final touch of realism,” says Focareta. “You can get pre-made decal sheets or have custom ones made. They go on after painting is complete and the body is mounted.”
For the detail-oriented hobbyist who wants their RC car to stand out, small touches matter:
“Don’t forget details like painting the driver figure inside, adding light buckets, or even LED lighting systems,” Focareta suggests. “Those little extras make your RC car look amazing sitting still or tearing around the track.”
Common Challenges and Solutions
Even experienced painters encounter issues with RC bodies. These solutions help overcome common problems:
Masking Bleed-Through
“Bleed-through happens when paint gets under your masking,” says Focareta. “Make sure your mask edges are firmly pressed down. For liquid mask, make sure it’s completely dry before painting over it.”
Fixing Mistakes
“If you make a mistake, you can sometimes remove fresh paint with isopropyl alcohol,” Focareta advises. “But once it’s dry, you usually need to work it into your design or start over. That’s why planning ahead is so important.”
Tips from the Pros on Custom Painted Bodies
“Practice on scrap Lexan before trying a complex design on an expensive body,” Mark Focareta suggests. “Most RC bodies come with a small piece of extra Lexan you can test on.”
For beginners, he recommends starting simple:
“Start with a two-color design with clean lines,” Focareta advises. “Master the basics before trying complex patterns or effects. A simple design done well looks better than a complex design done poorly.”
Conclusion
RC body painting transforms standard shells into personalized expressions of creativity. The techniques may seem backward at first, but the results speak for themselves – vibrant, durable finishes that withstand the rigors of racing and crawling while turning heads at every event.
