Your sander should work fine. I used both a foam buffing pad and some terry-cloth type buffing pads. If you want to speed things up, you could try the sanding in an inconspicuous area (I might try it next time). I couldn't find buffing pads made to fit my size of sander, so I just got some that had a fuzzy exterior that would stick to the velcro of the sander. Its not a lot of fun, but the results are definitely worth it. Also, I can guarantee that you will be extra-careful about not scratching it in the future!
