Guys, Scalecraft is 110% right about the fuse being made up of polyester resin. I tried bonding a thin ply plate to the inside wall of the fuse and once the epoxy had cured, it lifted "clean" off. I will be going to the auto parts store today to buy either the "EverCoat" of some type of polyester fibreglass resin. DON'T USE EPOXY to bond anything to this plane.
Happy Flying!
