ive repainted my guitar before.........after applying each coat of paint u gota sand it down flat before applying the next coat. then u can use a clear coat for the gloss finish. same thin sand down each coat flat before applying the next. then after sanding down the final coat, u can start buffering and polishing it to shine. the clear coat should consist of many many layers. more layers than the paint. and shldn't use to rough grit sandpaper ofcourse. check out projectguitar.com. they;ve got lots stuff.
