It's good to see this is finally catching on. I did mine over a year ago. I really liked the look of the finish. "Batmobile" is what comes to mind.
I did mine without the tires on yet. Not ideal. If you don't put it on with the tire already on, you'll end up doing some touch-up after tire installation. Better to do it with tires on.
Plasti-Dip is liquefied rubber. That's why if you put on a new coat, it "melts" into the previous layer unlike paint which stays somewhat layered.
Being rubber, it is prone to a solvent like gasoline. So don't wash your rims with gas and don't overfill your tank and you'll be fine.
All in all, it's great stuff. Just don't buy it in Canada, it's $20/can up here. Aboot $6 in the US. At 1 can/rim for 3 good coats, it's not too expensive.
