What about good ol hot fuel-proof clear dope, isn't that still an effective way to fuel-proof? I was planing on using clear dope for all the areas behind the firewall, going a little heavier in the fuel tank bay itself, & then using the heated epoxy method on the firewall for added strength & protection. Is this idea going to give me adequit protection or do I need to use epoxy for all of it? I'm trying to keep the weight down a little up front. I'll be placing the servos for the tail surfaces in the back of the fuselage as well. I'm hanging a Saito 100 on a .60 - .90 size plane and don't wanna turn it into an epoxy brick! Please let me know if I'm on the right track, if you think this won't be sufficient, I want to know that too. Thanks guys.
