First Christopher had me remove the fuel tap so it would not be destroyed in the "hot tank." Thanks to Roland Henry, one of the founder's of Three Mile Island Scooter Club, who loaned me his GS fuel tap wrench that fits the SS perfectly.
Christopher stressed to me the importance of coating the gas tank with 2-stroke oil immediately after the "hot tank" inside the tank and then to use PPG Metal Cleaner and Conditioner (see the paint stipping post). I went to Advance Auto and picked up some "2-stroke Pennzoil for air-cooled engines."
Ernie, at Smitty's Radiator, charged me $45 total for the "hot tank" and then he bead blasted the tank to clean out all rust debris and he dried it as he bead blasted. He quickly coated the inside with oil generously. The tank was slightly pitted, but the structural integrity of the tank was solid. I picked up the gas tank and then PPG prep'd it for the painter. It is highly recommended, by Tom Giordano
