ply so the bond is stronger than the wood.
I would try a little test piece without the peel-ply and a dry layup
. Make sure everything is clean, I vacuum the plywood
, and then either put it in the sun for a bit or heat it with a heat gun. This will later draw the epoxy further into the wood fibers as it cools, plus it prevents bubbles from exothermic heat.
I have used all the wrong kinds of fiberglass with West System and MAS epoxies and even then not a problem. What brands of epoxy did you try? I have used a local brand once and got weird things much like you describe.
