Well after a lot of inspiration from others and mainly from FriarJohn's posts, I took my tank to the shop. I just got it back from the radiator shop that tested it and sealed it. They sandblasted the tank. So my question is the tank has a light surface rust from the bear metal. So do I sand it off with a scotbrite pad or treat it with Muratic Acid to remove the rust before spaying primer on it?
