●General Purpose Laminating Resin ? This advanced ortho polyester resin works for repair and new construction. Secures fiberglass cloth, composite fabrics, woods, metals, and other fiberglass surfaces to increase strength, resilience, and long-term durability. ●Easy-to-Layer Application ? Our polyester resin stays tacky between layers and provides a reliable hold. It does not require sanding between layers. Use our finishing resin or a wax for a tack free finish on the last layer. ●Versatile Application Options ? A fast wet-out means you can apply this poly laminating resin to composites and FRP parts including cars, motorcycles, boats, marine vehicles, bathtubs, surfboards, and other DIY projects. ●MEKP Catalyst Included ? This poly laminating resin kit includes an MEKP hardener to help control gel time for a strong finish. Adjust the hardener quantity depending on the desired gel time, from 1 tsp/quart for slow gel to 3tsp/quart for fast gel time. ●Handling Temperatures - Application: 70°F - 95°F for resin and work area. Store resin in cool, dry area out of direct sunlight in temperatures below 77°F.
