You looking for 3M 5200 Polyurethane Adhesive/Sealant? It's a marine adhesive. Try one of the marine supply stores. Eastern Marine; rude not very friendly service, The Rigging Shoppe; not friendly rude service, Noah's Marine Supply; should be your best bet they are for boat builders. I went to Noah's years ago, they are good and helpful. Good luck. Don't glue yourself.......lol.
