Very few cars got the wheel treatment from the factory outside the few bodies the wheel coloring was offered to help sales. I believe it was most if not all on 30-31 bodies.
Of the top of my head, these were the ones that came with colored wheels.

The best paint for wheels would be urethane such as PPG Concept. The urethane paint gets very hard and looks great. Epoxy paints tend to degrade with UV light. Enamel paint is just not as tough as the urethane. You can put a hardener in, but you are best off with urethane. Keep in mind I say you are best of with urethane. The other paints do their job, but they are just not as strong.
Properly done powder coat is also very durable.
Based on my experience,
After you get the wheel done, take a sandpaper and make sure you have no build up on the two areas where the wheel touches the drum. My powder coated wheels would induce up to .012" of distortion in the drum. When I sanded the two major contact points down to bare metal the drum went back to its about .001" out of round.
