Having a buffing motor and polishing wheel are only 2/3 of the puzzle when it comes to polishing. You also need the right compounds. Eastwood carries them all, whether you are doing a rough polish to remove casting flash, or buffing aluminum to a mirror finish. Some of the compounds we carry include: Emery, Stainless, Tripoli, White, Rouge, and Jewelers. Plus we have greaseless compounds in many grits for the initial smoothing of your parts before the buffing starts.
