I use SPI (Southern Polyurethanes)in black. Black makes it easy to see the low (shiny) spots in the metal when doing your body work. They have gray, white, and burnt-red as well. For an epoxy it sands fairly easy. I've learned that you can reduce it to make the sheen more flat for frames, radiators, fender wells, etc.
They recommend a 30 minute induction time. Since I've learned the hard way to follow paint manufacturer's instructions I do this. Quite honestly it is a PITA if you short yourself an ounce or two when spraying. But it is a very durable product.
