Plastidip is easy to apply, looks good, and removable. Was about $6/can at Home Depot and you may need 3-4 cans to do 4 full wheels.
I plasti-dipped the inside lip on my slipstreams and wasn't happy with the look so I peeled it off. If your doing the entire rim there will be less masking (just the valve stems) so a much easier DIY job.
