Phenolic Glass G3 Laminate Sheet is a glass fabric reinforcement in a phenolic resin binder. The natural color is amber/brown. This grade has good heat resistance, high mechanical strength and low thermal expansion.
This is what we used it never was an issue about wicking fuel though?
Look up Micarta. Very machinable, strong durable fire resistant but not fire proof.
We used red or black sealant because surface is so slick and hard as to need.
Hope this helps ya.
Also permatex has a line of what the call flange sealer great stuff just read carefully to get rite one.
