The wheels on my 2014 911 have numerous stone chips, I am surprised on easy they chip as the car has 20k miles on it. What I'm wondering are they powder coated or simply painted?
Is there a service who can either hide the chipped areas so they are less noticeable, or a service who can refinish the whole wheel.
The other option is just to buy aftermarket wheels but that is my last option as I like stock vehicles.
