had a few scratches on the rear bumper that i wanted to get rid of. i've read about meguiars scratch x figured i'd try it. needless to say, it got most of the surface scratches out, but theres a few that are alittle too deep and didn't come out. i used my little 6" buffer/polisher to apply it.

didn't turn out too bad. is there anything i can use to get that deeper scratch out? or would i have to wet sand the clear coat?
