I would caution you to buy a low speed polisher. A high speed grinder will be much more likely to burn through. When I was in B&F trade school back when dirt was young the instructor drummed it into us pretty hard to NEVER use a grinder for polishing since they turn too fast. Now if you have a combo grinder/polisher with two speeds...........
