Just curious to know how different folks fuelproof/reinforce the firewall.

I know the old tried and true method is straight epoxy. Anybody tried anything different?

Thin CA is great for fuelproofing I wonder if it would be enough on the firewall or do you need the added strength of the epoxy?

What about aliphatic resin? Seems like it would be plenty strong and I believe its fuelproof.

It just seems to be that you could save a little weight and the pain of mixing epoxy by using something else on the firewall.
