This is Grade - A Premium Polyester Resin same that is used in most repair shops and manufacturers. This resin is a DCPD Type Resin- meaning it dries tack free without needing a wax additive These Kits Of Resin Includes 1 Bottle of Grade A Polyester Resin and 1 bottle of 2 oz MEKP Hardener . Polyester resin is the most common type of resin in the marine industry. It's perfect for low-cost repairs and new construction parts. Our polyester resin is great on vertical surfaces and also works great for fast glass wet out because of its low viscosity. This resin must be catalyzed with MEKP (Methyl Ethyl Ketone Peroxide) to properly cure. Our general purpose polyester resin is great for a wide variety of applications including, hand layup by brush or roller, spray on applications, marine, transportation, auto body, aerospace, general purpose laminating, FRP parts and more. This resin is compatible with all types of fiberglass and coring materials. Because this resin contains a styrene monomer it is not compatible with polystyrene foam. Review: Great resin - Easy to use and the finish was excellent. If you think you need one buy two because you’ll want it Review: makes a great speakerbox. - this worked perfect for building a custom speaker box out of fiberglass, i probably used way more hardener than i needed to as i only have about 20% left with 40% of the resin left but overall i'm very happy with the product, much better price than buying local in quart sizes. ## Features - Causes damage to organs through prolonged or repeated exposure. - Causes serious eye irritation. - Causes severe skin burns and eye damage. - Causes skin irritation. - Flammable liquid and vapour. - Harmful if inhaled. - Harmful if swallowed. - Heating may cause a fire. - Suspected of damaging fertility or the unborn child. - Grade A in Quality, The Highest There Is. - Very Cost Effective And Versatile To Use - Great For The DIY Users ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077YQTXJQ | | Batteries Required? | No | | Batteries included? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (719) | | Date First Available | 7 July 2019 | | Item Package Quantity | 1 | | Item Weight | 4.54 kg | | Item model number | 5 | | Manufacturer | Polymer Planet | | Material | Liquid | | Package Dimensions | 32.77 x 20.32 x 12.7 cm; 4.54 kg | | Part number | RESPOLY1GK | ## Images ![Polyester Fiberglass Laminating Resin,Gallon with Hardener - Marine Boat - Image 1](https://m.media-amazon.com/images/I/71T23mFOQwL.jpg) ![Polyester Fiberglass Laminating Resin,Gallon with Hardener - Marine Boat - Image 2](https://m.media-amazon.com/images/I/81NZYYGGRqS.jpg) ![Polyester Fiberglass Laminating Resin,Gallon with Hardener - Marine Boat - Image 3](https://m.media-amazon.com/images/I/81Yap+vzV6S.jpg) ![Polyester Fiberglass Laminating Resin,Gallon with Hardener - Marine Boat - Image 4](https://m.media-amazon.com/images/I/91yd0VvbsXS.jpg) ![Polyester Fiberglass Laminating Resin,Gallon with Hardener - Marine Boat - Image 5](https://m.media-amazon.com/images/I/81VEgdQQvYS.jpg) ## Questions & Answers **Q: Is the 2 oz of hardener provided enough for the gallon of resin?** A: Yes ! **Q: Hi. Is this can fix soft spot on boat floor** A: Well......Not if you want to fix it right. The soft spot in a boat floor can...and usually means the the wood under the floor is rotted and possibly even the stringers. If you put new matted fiberglass and resin over a soft spot in a boat floor it will most likely crack and bust when you walk in it. I just replaced a complete boat floor and stringers. I did use this product along with fiberglass mat to install new stringers and over the top of the new plywood floor. So far so good but I have not put the boat back on the water yet to see how it all holds up. Product is fairly simple to use but be sure to use a respirator and gloves. Good luck! **Q: Is this resin good for mold making, and what's the pot life time?** A: Very good **Q: What is the cure time?** A: Well, it depends. It is temperature, humidity, and mixture dependent. Two hours generally is enough time to cure, but I've been giving it 4 hours minimum....often over night. Once mixed, its very easy to work and getting really good results. I have not yet figured out the best means to mix it consistently because the varying climatological conditions in my non-climate controlled garage require different ratios. I will say this though, I love this product compared to other resin products I've used. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great resin *by G***P on 17 May 2025* Easy to use and the finish was excellent.
