Good point mpierich, just today we did a polishing job on a set of triple trees and started out with 240 grit. They were already fairly polished but just had a few deeper scratches. It really all depends on the condition of the metal at the start. Some of the old Triumph and Shovelhead covers that we have done had 1/8 to 1/4 inch deep gouges in them. At that point you really have no choice but to start at 80 sometimes even 40 or 60 grit.
A few other things I left out of my previous post is the fact that you want to clean between each compound and not to contaminate wheels with more than one compound. Then again, anyone who has taken Caswells advice and read the polishing guide should already know this.
Later All, D.J.
