Awesome shit dude. But I read the other DIY and was curious.

Ok my car is factory clear on all but the front fender.It's got some rattle can clear that didn't come out too purdy.But anyway I wanted to paint the car red or balck or red with a black roof.Camaro style.The car as it sits it white,black replacement bumper and black grille.Its a 97 Mirage 4DR and,damn I'm taking forever to get to the point.But ok heres the question what prep would be needed to get the spray paint to stick?I'm thinkin a bare metal sand but I could be wrong.
