Coaming caulk on Airalite

I have a Perception Eclipse Airalite 17’. A part of the coaming is separated from the cockpit opening. The coaming has a nice thick bead of some kind of glue or caulk around it. I know that airalite can be repaired with Super Glue, Polyester Resin, and Methyl Methacrylate, but the coaming is some other material, and I am not sure if this was originally a glue or a caulk. Anyone have advice about what to use?
