TotalBoat Polyester Structural Repair Putty - Marine Grade Long Strand Fiber Fiberglass Reinforced Filler for Boat and Automotive Repair

TotalBoat Polyester Structural Repair Putty is ideal for boat building and repair applications where high-strength structural bonding is critical, such as hull to deck, stringers to hull, liner to hull, and bonding bulkheads. It’s also great for bonding dissimilar composite, fiberglass, wood and metal parts. Its unique combination of high-strength polyester resin and long strand milled glass fiber provides maximum crack and impact resistance in large masses. Just bang it on in one big shot and it holds its shape well as it hardens. This fast-setting marine filler spreads smoothly, is quick to take a radius, and can be built up quickly without sagging. Perfect for fast, easy repairs to fiberglass parts, molds, hulls, decks, canoes, kayaks, runabouts,and more.Polyester Structural Repair Putty is waterproof and great for filling cracks, holes, chips and dents in fiberglass and gelcoat, above or below the waterline. This polyester putty is designed for structural bonding, not cosmetic fairing. For repairs requiring a smooth, easy-to-sand finish, apply TotalBoat Polyester Fairing Compound over Polyester Structural Repair Putty. After the fairing compound cures, sand smooth to prepare for gelcoat, such as TotalBoat Gelcoat with wax, or paint, such as TotalBoat Wet Edge topside paint. If you’re not overcoating the putty with fairing compound, you need to add an air-dry agent such as paraffin wax (4 oz. of wax per gallon of putty) or apply PVA (polyvinyl alcohol) over it. Putty comes with MEKP catalyst (use 1-2% MEKP). This economical, general-purpose, fiberglass filler can also be used to fill joints in sheet metal and fill cracks & voids in wood, masonry, and concrete, making it ideal for automotive, rv and home repair.
