i don't think the barrier stuff will help much. it's the sloshing that excites
the gas and produces the vapor pressure. we used to have the same problem
with those big 'jerry' cans in the army. and it gets worse if you fill them
up too much. admittedly, the heat and sunlight (in the army) didn't help any,
but i still don't think any reflective heat shield will help much for a
car-mounted spare fuel tank.
