I have a wheel that needs to be repaired because of a small amount of curb rash. I got two very different quotes. One guy only wants $100 to come out and says it can be done in an hour. The other guy claims the wheel is machined and painted, and that the entire wheel needs to be refinished regardless of the amount of damage. He also said the tire needs to be remounted and balanced. He wants $150 and said it will take 3 hours for the whole job. Who's right?
Unless it's so light that it'll buff out, the $150 one is a better bet.
I just had a rim reworked on a my 2010 VW golf after hitting a pothole so hard, that it couldn't seal with the tire properly anymore (once off the car and on the rim tire balancer, you could clearly see the flat spot, made part of the wheel look a bit like a "D"). The VW golf rims are aluminum, good quality, and pretty nice all around rims. I was surprised when I got the rim back, it was indiscernible from new despite having been "D" shaped, and having previous rash that was actually ~1/4" deep from riding up/falling off a curb, etc. (they apparently weld onto deep spots and then grind it off back to original shape/size/etc.).
Point is, the rim I took in was *heavily* damaged, and it came back out looking literally indiscernible from new. If the damage is bad enough that you're going to have it repaired, spend the extra $50. If it's something that'll buff out, just skip it/DIY.
FWIW, my mechanic set the whole thing up, tossed on a spare for the duration, etc. I got the job done for ~$125 I think (from $175 CAD maybe?). The shop discounted because they had the rim for an extra week, taking much longer than they promised.
