I recently picked up an 18" square setup of the factory option magnesium wheels. I want to have them powder coated as the factory paint is severely chipped. I wanted to ask the forum if anyone has experience powder coating these wheels or could recommend a shop in Florida to do the work.
So far every powder coater I have spoken with is not interested because the wheels are a magnesium alloy. Apparently to chemically strip them requires a dedicated solution that only works on magnesium ($$$), or media blasting with plastic/walnut/co2 which may still possibly remove material. The shops I spoke with also have concerns about the magnesium off-gassing during the curing process and possibly popping the coating.
I appreciate any guidance you can offer.
PS I have considered painting but the amount of prep and sanding is daunting and I am worried that even with a two stage clear on top they will still not be durable.
Check the temperatures involved too. Magnesium is kind of sensitive to temperature, not even accounting for flammability. You might be better off with a good paint.
