Painted over plasti-dip with Rustoleum Hammered Dark Gray Spray paint. One can did all 4 wheels. It's a close match in color to the nerf bars, but just a touch lighter.

Up close so you can see color difference...

Well... I found myself in Home Depot this morning and happened to walk out with 2 cans of Black Plasti-Dip.
At first, I thought I would just try the wheels and see how it looked. I thought it looked fine (different, but fine) and then decided to try the front grill and the lower center portion of the front bumper. I put 4ish coats on everything and I was pretty happy that there was minimal overspray unlike regular spray paint. I read somewhere on here the other day about using index cards instead of tape for the wheels... that man (woman?) is a genius.
I chose to go with this look finally, after trying just about every combination. The wheels aren't plasti-dipped anymore (back to stock). I'm going to try for HOJeepster 's look by painting a gun-metal/graphite color over plasti-dip tomorrow (trying to match the Sport Edition's tube steps/roof rack).
