Here is some experimenting. I'm still not real happy with finish, but with as bad of condition they are in I guess I can't expect much more without professional help. I sanded this wheel from 400 grit up to 2000 grit, then polished with tripoli and then Adams 1 and 2 (partially). Taped off the wheel to show the difference which you can clearly see. Wheels still have significant pitting I would like to get rid of.
