Aluminum Rim Damage

[Tmbcn3]

So, I have these 3-piece aluminum racing rims on my boxster and over the past year or so I have gotten a little bit of curb rash on the rims. How would I go about fixing this? Also, if I had to take it to a professional and refinish all of the rims, how much do you think that should cost?

No BIG deal. If just the polished lip, figure about $100 per wheel. That lip is probably not even clear coated. For example, my SpeedLines have this polished lip, not clear coated, and I've paid $95 to have professionally touched-up when I goofed (2).
