Could spray them down with/ wipe them with a thin coat of oil to keep the water away from the metal, thus causing oxidation...just a thought. Or even car wax on them? Not sure if wax would work or not. Hope that helps.

not sure if you have this product but it's a rim polish called Never Dull. works great to polish your rims but it will protect them too. i use it before and after heavy mudding so sand and s*** won't scratch em up. should work for you too. reapply every couple of weeks.
