TotalBoat Polyester Structural Repair Putty makes critical bonding applications on polyester laminates easy, strong, and permanent. Its trowelable, thixotropic formula spreads smoothly & won't sag, making it great for fairing vertical surfaces. Polyester Structural Repair Putty is also easy to shape, so it's ideal for radius forming.
Reinforced with long strand milled glass fibers, this high-strength, fast-setting marine bonding putty adds strength & dimensional stability to structural, boat building & repair applications including bedding and tooling. Great for reinforced bonding on hulls, decks & stringers, and multi-purpose bonding on FRP composites, core materials, and wood. Add 1-2% MEKP catalyst based on mass, ambient conditions, and desired working time.
Available in Quart and Gallon Kits that include MEKP catalyst, and 1 spreader.

| Cure Time | Dependent on temperature, catalyst amount, and mass of putty. For example, cure time will be 20-30 minutes for 100g mass catalyzed with 1% MEKP @ 77°F |
| Weight | 8.9-9.1 lbs./gal. |
| Shelf Life/Stability | Approximately 3-4 months (can be longer, depending on storage conditions). Keep container closed tightly, and store in a cool (below 75°F), well-ventilated place. |
Great for Structural Bonding, Filling, & Fairing Above or Below the Waterline
TotalBoat Polyester Structural Repair Putty uses a premium resin reinforced with long strand milled glass fibers for strength and impact resistance. In addition to structural bonding, bedding, and tooling applications, it's perfect for filling larger voids and gouges that are too deep for cosmetic fairing compound.
This high-strength polyester putty is engineered for structural bonding, filling, & fairing, not for cosmetic filling and fairing. For cosmetic fairing and repairs requiring a fine finish, use TotalBoat Polyester Fairing Compound over cured Polyester Structural Repair Putty. Allow the Polyester Fairing Compound to cure, then sand to achieve an extremely smooth surface ready for gelcoat or paint.
IMPORTANT!
TotalBoat Polyester Structural Repair Putty will not cure in air, and requires overcoating with an air dry material such as PVA (polyvinyl alcohol), paraffin wax, polyester resin with wax, gelcoat with wax, or TotalBoat Polyester Fairing Compound, in order to effect a proper cure.Technical Information

Shelf Life
Polyester resins have a limited shelf life and will, over time, harden in the container without the addition of catalyst. Shelf life is dependent on a number of factors such as product formulation and storage conditions. As a general rule, the shelf life for uncatalyzed polyester resins should be up to 6 months when stored in dry, cool conditions below 70°F. Warm to above 60°F before use.

I am impressed with the hardness of this stuff, but it's a little brittle. There is definitely a use for it, but not where flexibility is needed. I used it to repair some small holes in the keel of my wooden boat where a few screws rusted out,and left small voids-which caused leaks and some rot. I am very happy with the sheer hardness and strength. I am a little concerned about flexibility. If your application requires flexibility, keep looking... the right product is surely out there. If you don't need any flexibility, this stuff is amazing!
