I added a day compartment to my Chesapeake 16LT with a sea-lect hatch I put the hatch "ring" in the boat before I installed on the deck and now have it ready to glue the ring to the underside of the deck.

I've read of builders using epoxy and 3M 5200. I prefer epoxy but I've also read that epoxy doesn't stick well to polycarbonite.

What kind of glue should I use?

Thanks,
