Just make sure you use a quality coater, don't settle for some cheap schmuck tryin to make a buck.. The end result will be you doing the job twice and getting frustrated.
The powder coater I use is offering up a new black chrome powder, that looks friggen sweet. He has the product polished and then goes about a translucent black and then the clear.
Not so much a wheel type technique, but he also has the ability to color flake pretty much anything, the flake doesn't show until sun or light hits it directly.
Powder has come a long way over the last few years..
