No issues at all. I found that I got better results by NOT charging the wheel/paint due to all the tight pockets and crevices in the wheel design, so conductivity was a non-issue. JB Weld supposedly has metal in it, but I have no idea if it's conductive.
I preheated the wheels (10 minutes at 400 degrees) then sprayed them with the powder coat. As soon as the powder hit the hot wheels (JB Weld included) it would begin to fuse to the wheel. Once I had a sufficient coat of powder, they went back into the oven to cure (10 minutes at 400 degrees - the paint manufacturer's specification).

I wondered about that when I was coating my wheels. Not sure what the best method would be. Probably use a heavy coat of aircraft stripper to break down the finish. I expect it would take several applications. Here are a couple of resources I found online for how to strip powedercoat...
