more info: just remembered that when I was asking around about my wheels, the only thing that the guy at advanced alloys (and everywhere else I called) said was that if your wheels are shadow chrome finish, it can be fixed but is a lot harder to get the finish and only 1 place in vic does it - they all send their wheels there apparently.
Anyway, it's more expensive but can still be done (talking around $200-$250'ish per wheel instead of $100'ish normally)
