Polished alloy on that truck would look wrong. I think, now, that she has to go to work for a bit and acquire the proper patina to look right.
Oh, uh, 1958GMCnut, Dave, now I know where the last part of your handle comes from.
Those are wire brush marks, mostly, and will disappear after a few miles. I have a brush thing for my angle grinder. Maybe next time I'll pick a slower machine to clean the metal.
