Those wheels doubt have regular paint over them. Those things should be powder coated. If you want to re paint them i would not use regular rattle can paint because that's lacquer. Lacquer will take a few months to cure, so after u get it painted for sure it will start cracking or peeling even with your own fingernails.

Unless you want to pay for powder coating, the only good way to paint that is using car paint, carpaint primer and car paint clear coat. And by car paint i mean urethane enamel type of car paint like ppg, or maybe dupont. Do not go to the autoparts store to get duplicolor paint shop paint. It wil work but is not even close to ppg or dupont, not even think how far is from sikkens or HOK for example.

If you find a store the guy will ask you what kind of paint u have to tell him base coat clear coat. The primer u can get away with u-pol spray primer, pick the clearest they have, the primer will give you how light or bright the paint will get. I believe they have white primer but im not that sure, they have a light gray. Second option, tell the guys to mix you primer and put it in a rattle can, for a wheel maybe 1 can will be fine. U can ask them to mix the paint for you in a rattle can also (u can ask them to mix the clear with the paint also,) U-pol has a clear coat that is pretty good and that will work with the urethane paint.

I would Google something like how to paint a car or something because is the same process. As i painter i suck but i know what to do, u learn from your mistakes

Good luck
