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?
