Just some food for thought:
Start inspecting cars with dark-colored wheels, particularly ones with colors that have any level of gloss. I challenge you to find, on any given week, enough examples of wheels with 'temporary' coatings such as PlastiDip, DipYourCar, etc. that look like actual powder coating to fill your fingers on one hand.
Know that almost all OEM wheels are powder coated (which is a process where powdered pigment is chemically bonded to a wheel's metal surface), NOT painted (which involves no chemical bonding). There is a reason for this: Regular paint cannot withstand road debris, brake dust, and other road- and car-borne abrasives and solvents for thousands upon thousands of miles. What makes someone think a plastic coating (again: no chemical bonding) can?
For a 'temporary' look for a few hundred miles, sure: go for it. But I guarantee it will start to look bad very quickly -- and you can't just repair a coating from road rash, or a rock chip, or what have you. You'll have to re-coat entirely.
