If you're using a DA, not a rotary; you follow the advice on the forum, and you don't reuse any pad or towel that falls on the floor without washing it first; then the only thing you can hurt is your neighbor's pride! Go for it! Try it out on an old panel from a junk yard as suggested if you're a little queasy about it. It really is a lot of fun (in a twisted sweaty kind of way). :buffing:
