well i tried polishing them, but with not much luck. The parts that werent badly tarnished came out decent, just the parts that are really bad pretty much stayed the same. With that assumption i believe that the plating just isnt there anymore to polish. It looks more of a brass colour then your typical silver tarnish. There is a product made by Caswell Up here in canada, that its a cream that you put on and by the electrostatic energy created it plates the silver from the cream to the surface. I am going to try that and see if it works. I dont want to spend a lot of money just yet on them. Other expenses to worry about on the car over the little things... your input everyone is greatly appreciated. Shawn
