## Overview

TotalBoat Polyester Structural Repair Putty is a premium marine-grade, fiber-reinforced polyester filler designed for high-strength structural bonding and repairs on fiberglass, wood, metal, and composite materials. Its long strand glass fibers deliver superior impact resistance and elasticity, while the fast-setting formula offers 15-20 minutes of workable time and cures fully in 30 minutes. Waterproof and versatile, it’s ideal for boat hulls, decks, automotive bodywork, and more, providing a durable, no-sag application that sands easily and bonds dissimilar materials without shrinking or cracking.

## Description

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. Compare to Merton's Hull and Deck, 3M Marine High Strength Repair Filler, FGCI Polyester Putty, and Bondo Long Strand Fiber Reinforced Filler. All TotalBoat products provide great value and great results. 100% made in the USA.

Review: Goes on smooth, stays put and doesn't run, dries extremely hard! - After I reinforced a hole in the hull with fiberglass and resin, there was still a low spot. I figured it would take forever to keep filling it in with resin, plus the resin is extremely runny so it is hard to get it to stay in the low spot. I came across this putty and out of the can it is extremely workable, not runny, does not sag and stay put. Even mixing in the liquid hardener does not effect it or make it runny. I applied it to the hull and it literally took one coat and evened the low spot out. I mean it goes on so smooth, and you have plenty of time to work with it before it starts to get tacky. The price is very fair compared to other stuff like Bondo which they say you don't want to use for these types of repairs. I have yet to sand it, but it is extremely hard and nothing an orbital sander can't handle. Hope this review helps as I was going back and forth on what fiberglass to use.
Review: Appears to be good quality - I was fixing some holes in the boat and I’ve never actually used the polyester before. I usually use epoxy and personally in the future, I just will use epoxy and fiberglass. Nonetheless this does solidify well. This does appear very solid. I think it’s a good quality polyester, but I wouldn’t use it personally again.
