| Pressurized water would be safer than compressed air. If a seam lets 
go with water you get a little spurt of water. If a seam lets go with 
air it is much more exciting. Think of this as "hydroforming" your 
tank back to it's original shape. Somewhere I read a story about 
making motorcycle exhaust systems with curvy shapes by welding two 
pieces of sheet metal together at the edges. Then a hydraulic pump 
(hand pump) was used to pressurize water forced between the plates 
until the pieces ballooned up like a sausage.  That's the idea here.
Varnish and other crud remaining in a soaped out gas tank can 
vaporize when heated and become explosive. Keep this in mind too.
