A long, long time ago, there was a heavy duty discussion on refinishing a bathtub. In May we pick up our new-old claw foot. The guy says he has it up to the primer point. Since I know nothing, i really don't know what this indicates. Is he talking porcelin finishing or something else? Anyway can someone tell me where to get step by step instructions on refinishing this old beauty. And hello again to everyone out there.
