I asked the local place for some pxb 040 paint but it was too expensive for me, so i asked for some cheaper paint that would be identical. To prep them, i bought some scuff pads to get the clear coat off of the rims, and then i had a friend of mine paint them with a normal paint gun. No need to spend hundreds of dollars for a powder coating. If you can handle a paint gun properly, or know somebody that can, ask them. A couple of coats of black paint similar to the crossfire body paint wont look bad at all if done correctly.
