Re: Buffing and polishing???

These guys have a pretty good selection of pads and such. I use cotton covers over a foam pad and rubbing/polishing compounds to get aluminum mirror bright. You'll want to start with a more abrasive rubbing compound and then move towards finer compounds. 3M makes the best rubbing compounds, IMO.
BTW, use a slow speed if you are going to polish any painted surfaces. That machine has a pretty fast top end RPM and could burn in some situations.
