Apply 2 coats of glue to the 1" (25mm) lower edge of the PVC coaming skin and also to the 1" (25mm) wide area under the deck . After the cement dries, place 1 section of the coaming skin under the deck, starting at the aft coaming (below ropes) and heat to reactivate glue. Continue to apply heat and pressure while working around the coaming base.
