try an intertube stuffed in the tank and inflate easily. If there are no creases in the tank it should work.

large dents will pop out with some compressed air. take the petcock off and pressurize it up! just be careful you dont go overboard, you can pop the underside of the tank out!!

All kinds of different methods. Freezing water in the tank, the method mentioned above, pdr, etc. If its one dent in the side I would try pdr or I have seen the compressed air and blow dryer method, it works really well. Watch that method on youtube, its pretty neat.
