Replacment Gas Tank?

How was it putting that liner into the tank? Is it low viscosity? I was looking at the POR-15 product for the lining inside. I was thinking about simple epoxy chassis paint on the exterior.

it was okay....i washed it out with acetone, let it air dry for a little while, then taped up the opening and pour in the blue lightening, (which is actually bright green) LOL, sloshed it around for about 10 minutes turning the tank upside down at all angles, then drained it out and let it dry....it has the viscosity off....5w30 engine oil..if you will...
