What kind of clear coat are you using to keep the parts nice and shiney? I'm thought about polishing some small parts on my Banshee, but if I put all the work into polishing it, I don't want it to dull on me after a week.
You could clear but any scratch would be more noticeable. The clear wouldn't stick as well to a polished surface unless you roughed it up, then there goes your shine.
Waxing will seal the surface and stop them from hazing up due to corrosion. Some aluminum alloys will haze up in just a couple weeks if left out in the open.
Use a good old fashioned carnauba wax.
