Clear coating for aluminum

I thought you snow, and salt on the road people might answer this question for me. I would like to protect polished aluminum wheel hubs on my motorcycle. (sorry not tractor) A lot of vehicles have aluminum rims now. How do you protect them from the elements? Thanks, Stan
 
About the only permanent fix for aluminum is to polish it and have it anodized.

It's a plating process, still subject to scratching and abrasion, but will resist corrosion and dulling.

Much better than painting, as paint does not adhere well to aluminum. Comes in colors too.
 
I agree that anodizing is about the only good way to do aluminum. And with the cost of labor and materials, it might be cheaper to buy new wheels.

All I do is run my car through crewcar wash in winter. They wash the underside of the car.
Not 100% sure what the rims are made from.
Whatever it is, no oxidation in the rust belt.
 
Anodizing is a chemical induced, controlled oxidation process, not a plating process i.e. adding a different metal to the surface of another material.

Most aluminum rims have a heavy combination of anodizing, paint and some variety of polyurethane clear coat from the factory.

Any of which will develop ugly spots of corrosion via scratches, nicks, scrapes and over zealous cleaning over time.
You will see the clear coat peeling off of the edges of the exposed raw edges of a wound.
