The steelies are already black of course, but it's not a good paint and "grays out" quite quickly. I painted my steelies with a brush with a high quality, spirit based enamel. Prep involved good cleaning with mineral spirits, scuff sanding with 600 grit sand paper, another good cleaning with mineral spirits and then a tack rag. After 1st coat, scuff sand and tack before final coat. Most people prefer spraying, but I've had good results as described.

Aww shucks. Thanks Parkers09xB! Glad someone other than me likes the wheel covers.

@galon98, I am a big fan of Plasti Dip, as you will notice if you read any of my threads. It's raining like crazy here in NorCal, and the covers have held up just as good as the day I sprayed them. Good luck!

Sure thing 09Igloo! Uh oh do other people not like them? I think it's cool.

@ galon98:
Don't let the caps on the Plasti Dip cans fool you... they only come in a matte finish. Do yourself a favor and buy a can, then try it out on some random stuff. Before using it on the Igloo, I used the actual dip to coat my tool handles. My geek buddies like to spray their PC covers with it. It's definitely matte and it does not dry with a smooth finish. I'd describe the finished coat as "grippy" and "rubbery". It has a unique texture to it that you'll either love or hate.
My wheel covers got about 4 coats of black, then 2 coats of clear (yes, Plasti Dip comes in clear!)

When my wife still had her Jetta, I read on a couple VW forums about people using Plasti Dip on their actual rims. Although many scoffed at the idea, the people that actually did it had nothing but good things to say. One thing that they all stated as a drawback though, is that a lot of touch up was involved.
