Forget about the wheel, just repaint it. On the body, I'd test a little alcohol first. Not likely to do much unless the spray can had water borne paint in it. Don't know too much about today's clear coats, but older CC's and single stage would hold up to a mild wipe of lacquer thinner. The sooner the better. Then polish.

Of course the best answer is to take it to a pro detailer.
