I have another idea… (see photo)
Just think of the drinking of the wine as part of the project
If you ever want to smuggle 5 ltrs of wine past security
at a ball game
I took the (full) bladder out and stuffed it into the armpit area of my windbreaker. Then I carried the windbreaker in on my arm, with the wine bladder folded right on my elbow
. They frisked me and told me to hold my arms out. They patted me down, patted the lower parts
of the jacket, but not my arm, where it was.
Everyone got cups of water
, and we used the water
cups to drink the wine during the game
Back to the op...
Line-X is a version of polyurea, used to seal roofs, tanks
, protect truck beds, and most recently the military is using it as part of a multi layer blast proofing system.
If your tank area is accessible enough that they can aim a spray gun in there, they might be able to coat the entire interior
and turn it into one big tank, or whatever portion you like.
There's a video on youtube where they spray a piece of cardboard, stick it next to another piece of cardboard, and build the sides and bottom of a waterproof box. Then they put 2 gal of water in it and spray the water, sealing it in. It ends up being a very rugged 2 gal water jug.
