Not that you would invest more money in your new wheels, but a comparison of service and turn around time.
I dropped my 4 M5 wheels off for refurb at a vendor with a good rep, next day, called to say 2 of 4 wheels need to be straightened, I give the go ahead. These guys are the real deal, not a mobile type refinishing service, although they do off some mobile work as well. They have a specialized machine with rollers to straighten wheels, a large CNC lathe to clean up lips, media blast cabinets, spray booth, baking oven, Hunter Road Force Balancer, touchless tire machine and more.
Early morning of day 4, I get a picture texted to me. Not sure why it took weeks for someone else to resolve an issue?
Wheels fully media blasted, straightened, painted and powder coated with Shadow Chrome which is no easy task. This included mounting and road force balancing my 4 new tires.
They also phosphate rinse and bake the wheels after media blasting to make sure the wheels are not contaminated before paint/powder coating begins.
They are one of a handful of shops that supposedly are factory authorized to do the Shadow Chrome work?
Below is the result, I will not pick them up for a few more days, but the camera phone picture sure looks good!
For reference, Prince Wheel Service Monroe, NC. They will refurb wheels shipped to them as well.
Many good reports on other forums for these guys. I was impressed with their tools and capabilities, I have no doubt I will be happy when I pick up my wheels next week.
