Heat-resistant rustproof treatment for exhausts
So, one of my exhaust pipes has a couple of tiny dints, dents, scraps & scratches from the previous owner's stunts. And, predictably enough, those have started rusting slowly. I can sand & de-rust those, but without protective treatment of some sort, they'll just re-rust soon. So...
Can anyone recommend some sort of anti-rust treatment for clear metal (lacquer or whatever) that I could use on the exhaust pipe without a) having it peel / discolor because of heat and b) having it change the chrome color (significantly) ?
