sorry i didnt see your reply until just then :P anyway, as mentioned here, unless you are VERY confident in using a buffing machine, do not. i repeat DO NOT try the GMC "angle grinder aka sander" method. there are so so many things that could go wrong when using a rotary buffer that could cause pretty badass damage to your paint. my suggestion would be to outlay the funds and get a DA polisher. i myself am using a Meguiars G220A DA polisher with both 8006 polishing pads and 9000 finishing pads. at the time when i bought mine, they were going for about the 250ish price range, and add about 30 bucks for pads. another product which i use (purely for apply wax thou) is a Mothers Wax Attack palm polisher. As i mentioned, i only use this for applying my waxes/sealants as i dont believe it compares to the meguiars DA in terms of paint cleaning/defect correction, however some people do use the MOthers palm polisher for minor swirl removal. hope that helps, if you need any more specific help, feel free to PM me :)
