You only bear responsibility for your own actions
For what it's worth to ya I painted my wheels and am, so far pretty happy. I was using VHT Black Pearl for other trim and accents so I decided I wanted it on the wheels as well. I cleaned them up and squirted the paint then baked them in a 170 degree (F) oven for a couple of hours. Sure, it's not powder coat but it looks pretty good and if it doesn't hold up I'll do powder.
