Well I just dropped a chunk on a new brake booster, beautiful annodized thang, and within three weeks the dang thing is getting as powdery oxidation on it. Any suggestions?

By the way, I purchased it from a reputable dealer. Is there such a thing as a cheap annodizing (or irriditing[sp])job? I figured wet is wet, but I have been wrong about 12 times today already and it's only 11:30 am on the right coast. (vacation time to use)

I have had many components gold or cad plated over the years. It almost appears to be a plating problem. I would call the vendor/seller and question them. Also to help stop the oxidation try using a good enamel clear coat, this would help the oxidation but as I said I think something was went wrong during the plating operation.

thanks for the heads up, I'll call the dealer for clarification on the booster

Chances are that gold finish you're looking at on your booster is cadmium plated. It's one of very few " plating " processes that can be performed on steel, which I assume your booster is made of. Anodizing and iriditing is for Aluminum alloys, or possibly substrates that have been " coated " with aluminum. There is some work in the area of dying oxides on steel , which is more or less a controlled rust. Oh well , enough of that.
