Elastomeric Marine Sealant, Black 10 oz. Cartridge

A one-part, fast skinning (10 minutes) and fast initial cure (24 hours), multi-purpose marine grade synthetic rubber sealant with high strength, elongation, and durability. According to the manufacurer, adheres - without primers - to fiberglass, glass, metal, wood, and plastics - including Starboard®.
Seals, beds, and stops leaks — use it for thru-hull fittings, deck hardware, windshields, ports, hatches, rails, and chainplates.

Note that this product is a sealant - not an adhesive, nor an adhesive sealant - and therefore falls on the lower end of the "adhesive strength" scale.
