That's just one of those deals...those stupid alloy wheels are ugly enough to start with, and it's impossible to keep them looking new. I don't know why, but the Z24s never got nice looking wheels. Mine got so corroded that they're an odd shade between brown and yellow. I got a nice set of mags and I only use my stock rims for the winter. Anyway, if you're going to do something with your wheels, i wouldn't use chrome paint since aluminum doesn't look anything like chrome. If you're not buying mags and you're keeping your stock rims on, I would have them refinished if I were you. It's not that expensive and it gets them looking brand new.
