Have been cleaning the motor home before we shove off to Vegas, Polishing Aluminum I have to a science wheels and door plates, sills look like mirrors.
The Polished Stainless Steel skirt that runs up the side of the motor home about 2 ft and goes the length of both sides is still pretty bright, FIL was out keeping me company while I was waxing the bus said that the Skirting just didn't seem to Sparkle like it use to.
I can only assume that its corrosion that makes SS get dull. How can I tell if it has a protective coating on it before I try to brighten it up with (place your suggestion here) on aircraft we used a product called Never Dull but I know that they didn't have a coating of any kind on them.
