This is just a quick idea in case you wanted to try something different...
There is a flexible plastic coating available called "Plasti Dip". It has been around for yonks in the USA, but not easily available in Australia until recently. It has a multitude of uses, but recently people have been using it to coat wheels in whatever colour they choose (usually black). It can be peeled off at any time with no damage whatsoever to original item.
They have even demo'd painting an entire car in it. :)
In general it is a matte finish, but you can also add a specific "gloss" coat as well.
Try doing a search on YouTube for it.
