You should have about 15 minutes depending on temperature before it starts to gel **Q: Is there wax added in it?** A: no wax .fast curing. Don't make a big batch... Great stuff, easy to work with. **Q: I am doing a deck repair in my 68’ fiberform yellowstone. can i use epoxy primer over the repair putty and to seal the plywood?** A: Hi there, Thank you for reaching out. You can only put a coating other than Gelcoat/another polyester Laminating resin over the top of this product when it has been surface cured and prepped. The Polyester Structural repair putty stays tacky to receive other Polyester resin products. You would need to Seal it with Totalboat Polyester Finishing resin/Totalboat Polyester Fairing compound/Totalboat Gelcoat with wax/PVA then prep per primers instructions. **Q: How much area will 1 qt cover?** A: Honestly it depends on the thickness you need. This is for filling small holes or building up areas that have been damaged, not for laying fiberglass down. It will cure quickly so work in small batches. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by K***M on 17 August 2025* ### ⭐⭐⭐⭐⭐ Great repair and structure filler! *by A***R on 22 December 2025* ### ⭐⭐⭐ Stays Sticky *by J***A on 9 February 2026* ## Frequently Bought Together - TotalBoat Polyester Structural Repair Putty - Marine Grade Long Strand Fiber Fiberglass Reinforced Filler for Boat and Automotive Repair - TotalBoat-14409 Marine Gelcoat for Boat Building, Repair and Composite Coatings (White, Quart with Wax) - TotalBoat Polyester Fairing Compound (Gallon Kit) --- ## 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.vu/products/720933055-polyester-structural-repair-putty-fiberglass-marine-grade-fiberglass-reinforced-filler](https://www.desertcart.vu/products/720933055-polyester-structural-repair-putty-fiberglass-marine-grade-fiberglass-reinforced-filler) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
