David, Poly Tak is one part of the formerly Stits but now Poly Fiber system that is usually used for tube and fabric covered airplanes. The fabric that is used with the Poly Fiber system is Dacron fabric. I do not think you want to use Poly Tak for your application. If I were you, I would use epoxy and fiberglass cloth. Yes I would use micro on the raw foam between the foam and fiberglass cloth. Use only pure resin on the wood surfaces between the wood and fiberglass cloth. It might be a good idea for you to take a composite shool lesson from Spruce or whoever holds them now. Larry H.
Hi Mr. Larry, I was curious.... poly-tak..... is that what I should use between my foam and fiberglass? Im building just like Edwaurdo from Chile.... no side wood at all, just foam. Ive heard of doing the "hard shell" slurry over the foam to seal it then fiberglass over it but never heard of this POLY-TAK. What way do you think would be better of covering the plane? Any info is good info. David Swanson bdazzca...@aol.com
