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. ## Frequently Bought Together - True Composites Fiberglass Resin Polyester Resin Marine Grade Resin 1 Gallon with MEKP Hardener Polymer Resin Fiberglass Repair Kit Laminating Resin for Wood Boat Building and Repair - Fiberglass Cloth,6oz 50sq Feet E-Glass Plain Weave Glass Fiber Cloth,12 Feet*50 Inches Woven Fabric for Boat RC Plane Auto Surfboard Tub Pool Repair - Fiberglass Roller Tools Kit, 3pcs Fiberglass Resin Laminating Bubble Roller Set for Tub Shower Bathtub Boat Repair --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/57887494-fiberglass-polyester-resin-kit-1-gallon](https://www.desertcart.com.br/products/57887494-fiberglass-polyester-resin-kit-1-gallon) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-10-27*
