David asks- >poly-tak..... is that what I should use between my foam and fiberglass?
No... don't do it! Unless you're using urethane foam, the solvents in Poly-Tak (and all the other Poly-Fiber system components) will dissolve the foam right before your eyes. Poly-Tak is the "glue" that is used to secure unshrunk fabric to the framework of a fabric-covered airframe, either wood frame or steel tube. It is part of a complete system of fabric covering components and the only place I can think of that it could be used on a composite project is in the case where fabric is to be applied directly over wood. Just not sure why you'd do that, when you can use the proven method of applying a very light and fine weave fiberglass "deck cloth" over your plywood and preserve the complete system of composite epoxy resin that you'll be using throughout your airplane. Besides, Poly-Fiber stuff isn't cheap! And not only that, Poly-Tak can set up real quickly, much more quickly than any laminating resin or microballoon slurry that I've ever used, and is generally only worked a small section at a time. My two cents: don't even think about it!
