Abstract: A method for refinishing vehicle wheels includes removing the wheels with the tires thereon from the vehicle. The locations of the wheel weights are then marked on the tire and the weights are removed. The wheel and tire are then placed in a blast cabinet and the existing coatings on a face surface of the wheel are removed using a plastic blast media. Thereafter corrosion of the metal of the face surface is removed by blasting with rigid glass blast media. The tire is removed from the cabinet and any excess media is removed with an air blast. The tire is masked to prevent overspray. Thereafter the wheel is coated with one or more layers of coating. The coated wheel is then heated to facilitate curing, and the wheel weights are reinstailed prior to the coating being fully cured. The method of the present invention is particularly well-adapted for performance in a mobile service vehicle that can travel to the vehicle whose wheels are to be refinished.
