Its pretty simple, as long as you painted it with Lexan Style paint.
-Buy some DOT3 brake fluid,
-Grab a container large enough to hold your body, and round up some paper towels.
(Suggested by another forum the paper towels works the best).
-Place the body in the container and pour some brake fluid in to coat the body.
-Next wad up a couple paper towels, soak them in the fluid, and place them in the body so that they contact most of the painted surfaces.
-Pour a little more brake fluid in for good measure, and go watch the Speed Channel for 15-20min.
-When you get back, the paint should be soft enough to scrape away with the paper towel.
-Rinse it every now and then with warm water to clean the loose paint away, and resoak the body with brake fluid to continue.
-The results are surprising, and the body didn't cloud up.
