RE: Sig King Kobra Build
mike, looking good there. i used a competitor of gorilla glue (probond) to sheet my KK wings. before sheeting i taped over the retract/servo mounts so the balsa skins wouldn't adhere to them. i poured the probond onto a paper plate and used a 6" foam paint roller to apply it to the foam. it doesn't take a lot, i rolled the glue around until the color almost disappeared, just a clear sheen when you hold the wing up in the light. i then lightly misted the balsa skins with water and applied them to the wing core. next i place the wings back in their original shucks, then place that assemblage between pieces of plywood (mdf) and clamp the whole thing thoroughly. 24 hrs later you have an insanely strong bond. here is a photo of another planes rear stab being glued. have fun.
