Rotating a wheel while painting is nothing new, I have seen guys do it by hand. What I have done, is taken a rotisserie from a BBQ grill and welded on a plate to mount the wheel. This will keep the wheel in constant motion, you can lay on the paint and not get any runs. I made an adapter to work with steering wheels also.These motors don't have a lot of power so you have make sure you get the plate centered.
