Marine Sealant & Caulk

Bedding compounds for through-hulls, hardware and deck fittings. 3M 5200 is permanent and structural, 4200 is the same chemistry at half the grip so hardware can come off later, and Life-Calk polysulfide stays flexible and sands. Silicone is for windows and non-structural seals only. Fast cure versions for same-day work.
