Fortunately it's not. It's just irritating because I just had all the tins painted, put the bike together, and the recently the tank got dented. I was hoping to save myself having to find another tank (which is not gonna be cheap or easy) or paying to have this one fixed and repainted. I don't mind the expense as much as I mind running around with a tank with a dent that has been bondo'ed and painted over.
I've seen guys restoring old cars use a torch and cold water to shrink the metal on a hood, roof, or trunk lid that has been "oil canned" meaning the metal has stretched and a large section pops in and out when you press on it from something too heavy being on it, but Ive never seen this method applied to a smaller curved area on a motorcycle tank before. I have seen a guy inflate a NFL style football inside an old motorcycle gas tank to pop out a large dent once...but it still required a little bit of body work and painting afterwards because it didn't remove the dent completely and it cracked the paint a bit. And it sure made some noise when the dent popped out that scared the heck out of everyone else busy working in the shop...lol
