you wouldn't powder coat the red strip. the cheapest black option is just the normal black option. second, if you want a quality job it isn't going to be cheap, it costs money to do a good job and use a good powder coat. I'm not powder coater, but that is my understanding.

I paid $430 and $450 to powdercoat my wheels, for a grand total of $880
If you know that shop to be a good one, then that price range isn't surprising. But if it's not necessarily a really a good powder coating shop then I'd search around for different shops. |

Oh yeah. Here's a tip. Search around for a place that actually powder coats wheels and not lets say.. lawn chairs. There's a difference between powder coating a wheel and a bbq grill. Some places use high temperatures with short oven time which, in some cases, the heat causes the molecular structure of a forged wheel to change therefore causing hairline stress cracks in the internals of the spokes. To the visible eye it might look good, but if you put it under an x-ray you'll see random lines everywhere. I think the best technique that I've heard of is longer oven time, but lower temperature, if that makes sense. I think I've read somewhere around 275 instead of the usual 400 something? I'm not too sure about this, as I am not a metallurgist or anything. Just wanted to give you a heads up though.

Proper temperature depends on a) alloy composition and b) manufacturing method.
400 degrees F from what I heard should be ok for cast wheels. Forged wheels to be safe it's better using 300 deg or lower, from what I've heard. |

I just paid $200 to have them painted with 3 coats of black and 3 coats of clear...plus thin red stripe under the clear coat. Shiny ass hell! had to prep them myself though, that means, degrease/clean, sand with 320 grit, then clean again, then let the body shop do the rest.
