I am just getting ready to cover my 4*40 kit and was wondering if I should fuelproof the compartment that the fuel tank sits in. On the 4*, there is no hatch that the feul can leak through on the top. However, fuel may come through the hole in the firewall that my tank hoses go through. Any thoughts? Seeing the sheeting is all done, I'll have a "fun" time getting the compartment feulproofed, but it is doable. Also, when I fuelproof the firewall and front end of this thing, I think I'm going to just use epoxy. Is this satisfactory? My trainer (ARF) already had this done when I bought it, so this is my first time. Thanks for the help
