BoatLIFE LifeSeal® Sealant Cartridge - Clear

The BoatLIFE LifeSeal® Sealant Cartridge in Clear is purpose-built for fiberglass boat repairs, deck work, and waterproofing applications where durability and reliability are non-negotiable. After years on the water, any experienced angler or boater knows that superior sealant is the difference between a boat that stays dry and one that develops leaks at the worst possible times. This marine-grade cartridge combines the best properties of silicone and polyurethane, creating a bond that withstands saltwater exposure, UV rays, and the constant flex and movement inherent in modern fiberglass vessels.

LifeSeal® formula delivers fast curing times without the offensive odor that makes interior cabin work miserable, while maintaining exceptional adhesion to fiberglass surfaces where other sealants fail. The non-sagging characteristic keeps the bead in place during application—critical when sealing overhead hardware, through-hull fittings, or console edges. The sealant resists corrosion from metal fasteners and hardware, won't yellow over time, and creates a permanent flexible seal that flexes with the hull without cracking or separating. This low-odor, non-corrosive design means you can work below deck without ventilation nightmares.

Whether you're a fishing guide running a charter operation, a weekend boater maintaining your own hull, or a serious angler who spends 200+ days annually on the water, the BoatLIFE LifeSeal® Cartridge handles transom seams, gunwale joints, deck hardware installation, and cabin window bedding with professional results. The 0.8 lb cartridge fits standard caulking guns for precise application control. It bonds reliably to fiberglass, gelcoat, metal, and rubber—the exact materials found throughout vessel construction. Keep several cartridges on hand for seasonal maintenance and emergency repairs when you're away from the dock.
