Well I have a few paint chips on my front and rear bumber (who doesnt) and most look like they are from rocks and such. So they are not just chips, they are spots where the paint was pushed back causing a lump right next to where the paint is now gone. My question is should I try to sand this area down and then use the touch up paint? Or is there some way to do this? It's gonna be awful hard to sand just that tiny spot flat. How did everyone else use touch up paint? I also have a long scratch (someone keyed my door) can I use the paint to fix this also?
