Your cart is empty. 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.

It is a very well made product when you mix and apply it right. There was a rust hole in the back of my sons vehicle the size of a baseball. We used this bondo and the completed look is not noticeable. I only wish I took before and after pictures to show.
