A guy at work has been running his GTO ( he bought it new) through the autowash with brushes, the car looks like someone took steel wool to it. He asked if I could help him and polish his car for him. I'm doubtful I'll get it all out as I only have a PC, so what would be a good filler glaze for a black car to be topped by collinite. Don't worry, I slapped him a few times for the car wash thing and gave him a lesson in proper car wash techniques.
