You wouldn't ship Int'l by any chance? I've been playing the purist porsche type guy and hidden my crush for the angel eyes for too long
I have a set here that could do well in a garbage can. Lenses were off for a few months and since a few people played with them. They are completely wrecked. I'll try your technique on a hot day here and see if I can rescue those.
If this works I'll report back to confirm that you have found the perfect combination of abrasive grits for lenses restoration!
