It won't last a year. Wheels take a lot more abuse, dings, rock strikes, and water submersion than other parts. The door handles, gas cap, and front grille on my MINI have lasted over five years with four coats with touch ups on the grille every six months or so. But when I did my entire motorcycle with the same amount of coats, it only made it about two months before turning to complete crap.
The finish will technically last, but it'll look awful.
