I am painting my wheels black, had thought about using the spray bedliner. Any thoughts on this? I just want it to look OK and last a good while. Looked into powdercoating but it seemed a little pricey ($40/wheel +$25 ea. if sandblasting needed) Also, will the factory tire mount hold a 33" OK? It seems a little flimsy and I would hate to swing it out and have it fall off and take a bunch of sheet metal with it.
