hey guys, I have a scuff down my drivers side door that I'd like to remove. I cannot really describe it as a scratch since it appears to be resiudal material on top of the paint, not a surface scratch that I can feel. I tried simply rubbing with a chamois with no luck. I am thinking I will need to try a wax, rubbing compound or polishing compound. I am DEATHLY afraid to bring something abraisive to the paint. Any suggestions?
