Well my almost new PSC beadlocks are not taking to the harsh winter were having here in northern va/D.C. area. To start I am not bashing PSC. I kinda worried about this from the get go, but never expected the harsh winter were having here. I have the wheels powder coated black, but the bead lock rings are bare aluminum. They are starting to get a fade to them and look oxidized. Is there anything I can do to these and leave them with the bare aluminum look? Anyway to clean them up? Option 1 is find a way to clean them up and leave them the silver alumin they are. Option 2 is I considered pulling the rings off, sanding them, and painting them with duplicolor spray on truck bed coating. My bumpers are done in this stuff and its durable. But the reason I left the rings unpainted is rock rash, they dont look as bad bare aluminum if they take a hit/scrape offroad. Thanks for any help.

Also is there any preventive maintenance I should be doing to these wheels in this salty enviroment?
