Alum. is as a non-ferrous metal, = no iron content
Alum. however will oxidize because of its Zinc content, our rims have a clear coating to prevent this effect.

Aluminum does NOT rust, rather it gets a white powdery corrosion.
Most alloy wheels are treated with a clearcoat of sorts anyway. Now if that clearcoat breaks down, then yes, you could have some corrosion but they shouldn't rust.

Thanks folks.
I have this guy whos says aluminum does not oxidize because it is already oxidized. I dont know what that means. And that clearcoat is aluminum oxide which is created by a reaction with the oxygen in the air. Sounded like crazy talk to me so I thought I'd consult the board. Thanks again.

Well, you're buddy is not too smart in the ways of metals. All metal will oxidize, rust is just iron oxidation. Take raw aluminum billet and expose it to warm salt air in say, Florida. It will look like crap. Even Stainless Steel given a long enough exposure to the right elements will oxidize. That's why most all metals are anodized, alodines, or coated with something. Stainless is one of the few exceptions as it can take normal conditions and hold up fine.
