In my experience as a machinist I have found that aluminum forms it's own invisible oxide layer immediately after cutting or polishing it. Only preservative needed is wax to help water roll off. I have had polished bare aluminum pieces on other bikes for years and all they needed was an occasional wash and wax.
Check it out.
I polished all the aluminum on my XJ and all I did was wax them. It's only been a few weeks since I did it but so far no spots or fading at all. Clearcoat will eventually deteriorate.
Good luck.
