I had been thimking of painting mt calipers also. What method are you going to use when you do it...G2 or a spray like VHT?2022 M3 LR - I’m about to paint mine, orange. I cannot understand how someone would think that they don’t have the tools or skills to remove a tire. Good lord, how would one replace a flat tire or rotate them??? I’m amazed that one would think it is easier to clean the calipers and apply the vinyl through the wheel spokes than to just jack up the car and pull a tire.
The only reason I haven’t painted mine yet is because I want all 4 corners up and paint them at the same time. At least your vinyl makes it easy to do this one at a time. Seems like you have a great idea.
