The Stovebolt Site Forums The Shop Area Paint and Body Shop Best Type of Sandpaper

Hi 120 grit wet or dry paper works well to start with. After you get some primer on 400 - 600 grit wet or dry works best. Harbor Freight sells a 4 1/2" right angle grinder ( sometimes for under $20) that you can use a knotted wire brush with.
Good Luck
