I like those wheels alot - tried to buy a Denali truck with those wheels awhile back and they wanted over $50k for the dang thing !
If you could get a air powered die grinder, a small one, that fits in your hand easily, and find a foam pad, like the Mothers foam pads that are made for drills, and use something mild like Zaino AIO, with just a little cut, and Zaino sealant in it, I bet you could make them look super shiny and at the same time, give them a coat of Zaino for protection.
Hard to see how they really look in the picture, are they just cloudy or what ?
The foam pad would save hours of hand polishing with something else, but if you are not in a hurry, hand polishing definitely takes out the risk of getting power tool back of pad too close to metal and doing damage; of course you always tape up the mandrel behind the pad or put foam on it, right ?
Good luck with these, I sure like them !
