AutoZone sells this kit that has the buffer style discs in them and you attach them to a hand drill and spray with water and start buffing. They are in a small brown box and you get about 6 discs and the drill attachment. Just keep spraying the surface with water ever so often. This worked great for me. I didn't know about the Mothers though, I'll have to try it.
