I'm going to attempt stone chip repair on my car this weekend and after any hints and tips from people. What polish, sand paper, that sort of thing. I'm using this Stone Chip Repair Guide - Detailing World as a basic working guide but he uses a porter cable polisher and I dont have one. What polish or compound do you think I should use? I'm not expecting fantastic resaults but something better than looking at white spots or shoddy stone chip repair. Any hints or tips would be great.
