I havepurchased the ZOOPs coating kit, but it is still in my cabinet and I have yet to use it.
I presently polish my wheels with the mothers aluminum polish and follow that up with the Mothers billet pollish, to get a mirror finish. I then use a metal protectant from a company called "Wizards". The metal treatment is called "Power Seal" and it works really well, in my mind. I have a set of polished billet wheels on my show truck and I also have a set of billet wheels on my 91 daily driver and they stood up well to the weather with this stuff.
