I'm re-painting the wheels on my S for the Old Car Festival at the Henry Ford in two weeks. The car is going to the pinstripe shop on Monday and can't wait for the show.
That's the way I paint my wheels too, on a piece of pipe between two sawhorses.
I hang my pipe from an old swing set frame--useful for hanging fenders too (paint both sides at once).
I hung mine up in my backyard. Didn't want paint inside the hubs, so blocked them with tape.
