Whatever you do PLEASE make sure the powder coater you use does a proper surface prep before coating.
I used a place in Tampa to PC my Honda Gold Wing wheels and all they did was bead blast them - and now the front one is peeling really bad
It's gonna cost as much to strip it off as it did to do a crappy coating job!!
I suggest you ask the place what brand of powder they use, then read the company's web site to find what is recommended for surface preparation and ensure they follow it.
I'm tired of mine coming off in big chunks!!
