Thread: Not sure how to proceed with cleaning

as per my polishing SS -for other than shaving porpoises-, i'd say that you're safe going to 600 on the paper before polish. you can control paper better than polisher. i have paper to 2000 grit, and it may go finer, but 600 is pretty slick.

and yeah, bench grinder make into polisher.

can't reply offhand on the rouges, have to look it up like anybuddy else.
