The guy who fixed mine worked behind the Porsche dealer building doing their cars Plus Private Jobs.
Call around to such dealerships and somebody will know of someone;
The "Grey-Machined Aluminum" wheels I have are a little hard to match the color on; 99% of time I don't notice it, though. (I DO LOVE the SXL's 360 cameras' view to help prevent this!)
Problem is (Mine wasn't as bad as your's) my guy wanted $90 and a "Wheel Shop" wanted $170; Shop and get multi-quotes while confirming work quality with pricing.
