So today when parking i finally heard the horrifying sound of my dropstar 22" rim grinding up against the curb. Needless to say, I suffered about 18" of a circumference curb rash. It went straight through the custom paint, and I don't know what exact color the paint is (just bought the car), and I don't know where the former person got his paintwork done. What should I do? Is the touch up paint method effective?
