I used to have a shop that removed powdercoating, and your wheel clear is clear powdercoating. As noted above it is not a easy procedure to remove, prep and recoat a used wheel. When new, a much simpler process. Overall, for looks it would be less expensive to purchase a new set and start over. Might want to hunt for some take offs from a rv dealer where someone want a different wheel and removed the ones that came with the trailer. When I had a 5th wheel I upgraded from 16 inch to 17.5 inch wheels and tires. Sold my almost new set to a fellow wanting to improve his set up.
