Well I picked up my gas tank from the radiator shop today and I can't say I am very happy with it. I didn't look at it very close until I got home but when I shook it I could hear a rattle. After several minutes of shaking it I got a screw to fall out of it. I am not positive but pretty sure that screw wasn't in there when I dropped it off. Also several ounces of brown water poured out of it. If I wipe the inside with my finger I can get white chalky stuff to come off. It took about 5 times of rinsing it with a few ounces of gas to start getting gas to come out that wasn't red rust colored. The tank was in great shape when I dropped it off, just a little dirty inside. I probably could have rinsed it out myself and used it and saved $90. I was temped to do so but I thought I would avoid problems of a plugged filter and carb and just have it done by a pro. I had this done years ago on a much newer tank and what I remember was it came back looking almost brand new. I am really not sure what is involved in the boiling out process. Were my expectations too high or did I get a poor done tank?
