Hi guys. Looking for your opinion on a NON-random orbital polisher. Just one that spins. I've got a couple of cars that are in severe need of some TLC, and I've tried using a Craftsman random orbital. It just doesn't do the job. I know these can be hard to use and it's easy to mess up- that's a chance I'm willing to take. I just would like to know if anyone has used them and what models to look for. Can an angle grinder be used, if it has a low enough speed available?
