(May want to start at 220 grit depending on how bad your rim/scuffs/paint/curbage is) 400, 600, 800, 1000, 1500, 2000 grit sand paper are what i used. Don't skip in grits. Also I wet sanded when i got to 1500-2000 grit (Not sure if you need to, but I did). Took me about 2 hours per rim/wheel, and that's not including polishing/buffing them.
