I used this pad for heavy polyurethane foam overspray and it worked great! You HAVE to keep it lubed well and watch for the edges of glass. It will mar and streak if it gets dry or if you catch a corner and stretch/tear the rubber. Best use of this pad was by hand.

Dont buy, wait for the fine grade pad. Tried this pad, terrible marring all over paint. Did make paint feel 'clayed' but will have to add another polish step to get rid of the marring. I hope the fine grade pad fixes this issue. I tried it on every different speed, and even by hand, same marring.
