Believe it or not, white Carpenters glue works well with Robart hinges. After it dries it is virtually impossible to pull the hinge out without tearing out some of the material. In foam wings I use a 3/8" dowel, drilled for a tight fit for the Robart hinge, white glue it and insert into a predrilled hole in the foam. Any excess glue is simply cleaned off with an exacto knife after it dries. Where water is involved, epoxy will work well. Put some vaseline on the hinge area to keep it flexable and to prevent binding.

There are others systems, but this has worked well for me over the years.
