I have a chrome fender I want to put on my current build. Need to find out how to clean the chrome (the old cola and alminum foil trick?). The fender has some oxidation and small pin-hole rust spots here and there. I tried to clean a little part of it and so far most of the oxidation and rust spots sem to come off with a regular dry rag rubbed vigorously. But what do I do after the chrome is clean and gleaming again to keep it that way because one or two wet days and the tiny rust spots will no doubt come back? Car wax, clearcoat,.....? Any suggestions?
