Repair fiberglass, wood, and metal like a pro with this 1/2 Pint Fiberglass Resin Repair Kit. This all-in-one kit includes everything you need to mend cracks or holes: resin, hardener, fiberglass cloth, mixing tools, and an instruction guide. No prior experience is needed – easy step-by-step directions walk you through mixing and applying the resin for a quick, solid repair.Each repair cures to be 100% waterproof and long-lasting. The high-quality polyester resin hardens into a rock-solid, marine-grade seal that won’t rust or rot. It’s perfect for patching leaky boat hulls, fixing cracked bathtubs or hot tubs, and reinforcing rusted car body panels. Once cured, the fiberglass-reinforced patch withstands water, weather, and vibration, so you can trust it to hold up over time, even in demanding conditions.This kit’s resin bonds strongly to multiple materials. Use it on fiberglass surfaces, metal sheets, wood, ceramic, or concrete. From repairing chipped fiberglass on your boat or RV to sealing a cracked shower wall or swimming pool lining, to rebuilding a section of auto body around a rust hole – this one kit handles a wide range of projects. The finished repair is rigid and sandable, so you can file or sand it smooth and then paint over it for a seamless finish that blends into the surrounding area.Fast cure, easy finish: The resin sets in about 2 hours (at 75°F), which means most small repairs can be completed in an afternoon. You won’t be waiting days for it to dry. As soon as it hardens, you can sand, drill, or paint the area as needed. Why spend more on new parts or professional labor when you can do it yourself with professional-quality results? This Fiberglass Resin Repair Kit gives you the power to save time and money by restoring damaged parts on your own. Keep one on hand for emergency fixes and long-term maintenance – it’s a reliable solution for anyone who values sturdy, permanent repairs.

  • All-in-One DIY Repair Kit: Complete fiberglass repair set that includes 0.45 pint (7.2 oz) of resin, liquid hardener, fiberglass cloth, mixing tray, applicator stick, spreader and instructions. Everything needed for a quick repair – no extra tools or experience required.
  • 100% Waterproof & Permanent Bond: Industrial-strength resin cures to a completely waterproof solid patch for long-lasting repairs. Won’t shrink, crack, or pop off over time – ideal for sealing leaky boat hulls, fixing rusted auto panels, or patching wet areas like pools and tubs.
  • Strong Multi-Surface Adhesion: Versatile formula bonds to fiberglass, wood, metal, concrete, and more. Restore cracked boat fiberglass, repair damaged car bodies, mend surfboards, gutters, or bathtubs – one kit handles it all. Forms a tough fiber-reinforced patch on most surfaces.
  • Fast Curing – Sand & Paint in Hours: Quick-curing resin sets in as little as 2 hours, letting you finish repairs fast. Once hardened, it’s easy to sand to a smooth finish and is paintable for a seamless blend with your surface. Get professional results in an afternoon.
