Has anyone had a set of Magnesium rims powder coated? Im planning to get a few items powder coated, and i will be picking up a set of OTK mags that have some paint flaking, and thought about having them done at the same time.
I don’t know the answer but I’m interested to hear the responses. I have a spare set of mag rims that are ratty looking so I would like to powdercoat them if it’s possible.
I know people have powder coated rims before, does it change the heat transfer, probably. I’ve wanted to try to get a set cerakote’d because it’s a more durable coating and is very thin so shouldn’t affect heat transfer as much. Might be prohibitively expensive however.
It is a good question that I sort of know the answer. Paint / powder coating is an insulator so the tire will run hotter. How much I don’t really know. If the wheels were painted to start with, then you are probably ok. Most OTK wheels have a chromate finish not paint to prevent corrosion and are painted with clear coat on the inside (where the tire mounts) to prevent air leakage. Magnesium is apparently very porous and can leak air. Don’t ask me how. It is what I have been told.
