Penguin Fart Racing
RCTalk Qualifier
Car bodies are painted on the underside. Body shell exterior is "straight" plastic. When my RC body exteriors get scratched up as they "turn turtle and slide on tough pavement, I buff out the scratches with successively fine wet sand paper and emory cloth. Instead of wetting sand paper with water, I use concentrated dish soap. After the emory cloth, I use a patch of closed cell foam from a can coolie dripping with swirl and fine scratch eliminator for full-size cars.
