well i wanna sand down the side of my case, like the circle that says yamaha, and you just sand it down with like 1500 wet sandpaper right until its smooth and all the paint is gone, then you polish the crap out of it right. but ive heard not to clear coat it but if you didint clear coat it wouldint it rust and stuff, so who clearcoats it and who doesent when they polish stuff?? oh yeah also some plastic pieces on my engine cases are really light colored and scratched up, how do i get it back to the dark black color it should be? just sand it??
