When stripping down an old aluminum wheel to sand/polish, will regular old paintstripper take off all clearcoat without hurting the metal? Also, when finishing, most people like to use clearcoat so I've read. Can you just wax it instead? Or is that a bad idea because wheels are so close to the ground and get dirty so easily you'd be re-waxing once a week? Or can you clearcoat and then wax?
