At the very least you could buy some black touch up paint, smooth it a little with a Dremel grinder wheel, and make it look less noticeable.
(MUCH harder to find matching touch up paint for the Rado color wheels, so you are lucky in that respect.
)
From what I've seen, most places (near me anyways) want MORE THAN what a new wheel (discounted, NOT from the stealership!) would cost, to fix something like that.
I would probably just find a new one, or a perfect condition used one, and keep that one for possible spare tire use (not sure it would fit in the well or not).
