Glue for foam strips

I've actually gone no farther than my local Home Depot for the polyurethane glue that I use for all the foam strips. It is waterproof, stronger than the foam, and when cured it can be cut with a knife or sanded. I have used both types above and actually prefer the PL Premium adhesive. My one float survived the winter outside (dampness and cold) with only the inner laminate complete. I think this glue works fine. I also did a test to make sure that my epoxy had no issues with the glue. It expands as it cures and does some foaming.
