Yet another option:
Sherwin Williams offers Barrett Jackson Restoration Paint Kits, in gallons and quarts. It's 2-part urethane, so it should paint and last better than Rustoleum. Still single stage, no clearcoat needed. Pricier than the Rusto option, but cheaper than full custom stuff. It comes in a Satin Black. Lots of videos on Youtube about it.
