Nope, I'm going to use Eastwood's
vinyl dye paint product that is specially formulated for hard plastics. I have a concern that clearcoat could craze and crack if not high-elongation. Black colors, in my limited experience, tend to be pretty good against UV damage. Since this product is suitable for vinyl seats and tops, I believe it should be UV-resistant. At this point, I see no need for any other coating besides the paint over the etchant on top of the cleaned wheel.
I'm no paint expert, Eric. I bet others could offer some suggestions, but for me, I prefer to skip the clearcoat.
(Removed the steering wheel last night and found some cracks that I missed when it was mounted on the car. Tonight I hope to get these missed areas filled.)
