That's a small wheel. We use a 10" x 4" 3M wheel for all the
stainless on boats and such. Couldn't do without it. Yes, they're
expensive. The advantage is that they do metal removal, scratch
removal and final polish all in one step, replacing about three
different abrasive grades and their corresponding arbors and such.
