I try to keep my wheels nice but the inside barrels don't get any love. The chrome is not as nice as the outside of course and they really dont show that much. I have been thinking about sanding and painting them in a two part epoxy or Por15.
I have a small air leak in the left from which turned out to be the TPS stem. So need to replace seals on that.
While off I decided to take the opportunity to clean the inside. Used Adams wheel cleaner and wheel woolie which basically did nothing. Then pulled out their #1 metal polish and give them a good rub down.
That helped tremendously and finished it off with some liquid paint sealant.
Still undecided about cleaning the other three or just going ahead with some sort of epoxy coating.
