I do a lot of polishing since I detail boats, RVs, and Big Rigs. I use old wool pads 5" on my pc and orbital which works great on tanks, bontoons. Then I use my drill with some pads for the wheels and a lot by hand. Usually when I get the chrome or aluminum it is badly oxidized and takes a lot of work to get them back to new. Customers love to have it shine and pay extra for the hard work. Great pics!
