Painting resin plastic parts are more easier than painting standard plastic parts and kits and looks better BUT when getting paint off from the parts or body can be a problem because not just model car striper is the only thing that gets paint off. Light mild paint remover is CASTORAL Super Clean can be had at your local Walmart or Pine Sol. If something stronger is needed you can use Brakefluid BUT just remember do not soak for too long and keep a check on it or just rub it on and clean off with a damp rag. When finished just wash with soap and water and don't let brakfluid dry on the plastic. There is a good chance it will not damage it but in some cases it could warp it. just use slowly to find this out. Most of the time it harms thin cheap plastic.
