I’ve been thinking about an internal bladder when I make my fuel tank, and one thing struck me – infusing aramid with viton rubber (very low viscosity) – wouldn’t that get the best of both worlds – really strong bladder and fuel resistance to boot. then sling the entire thing in a CF/Aramid tank.

I can’t see anyone selling VITON compound on its own though – seems to be as a finalised product.

Any thoughts?
