I recently plastidipped my wheels. It was easy to do, and while it does take some time to put an appropriate amount of the plastidip on, it went uneventfully.
I would suggest that you clean your wheels very well, and pay attention to getting the outside lip of your wheel to have adequate coverage, otherwise it'll peel off pretty easily just on that outside diameter once you start cornering/driving aggressively. Other than that, which was my fault, it's held up to scrubbing/vigorous washing no problem at all. I re-did one wheel for the heck of it and the plastidip was relatively easy to remove.
It's a very inexpensive way to mess around with colors, and it's 100% reversible. I am tempted to try some interior pieces, but not sold on liking the texture for that application.
