Powder coating is a fairly simple procedure, and, there are some really trick powders available. 17" wheels might be a little too big for the kitchen oven, but, I've done some smaller stuff in an old electric oven that I can use outdoors, plugged into my welding outlet. My first attempt at this was a couple of solid engine mounts that my son and I "cooked" in our kitchen. It took a while for the fumes to dissipate, and, even longer for my wife to calm down.
It will last almost nearly forever. You have to sand-blast the stuff off if it's done right.
