I've got one of them, it works great for polishing up stuff. Just goto like a jewlery store, or maybe a homedepot, and pick up some polishing rouge, it comes in this big brown stick, crank up the toy, get some on the big round cloth thing and put it to work. you'll have to keep putting on the rouge as it goes pretty quick. but for big jobs I usually use my hand drill w/ a really big cloth circle thingie. it works great on all metals. Anyone else have a compound they think works really well?
