Get Your Boat Back in the Water: This industrial-strength fiberglass mat absorbs resin rapidly, ensuring dependable results for your DIY marine repairs. Use it with polyester or vinyl ester resin, but avoid epoxy resin. Get your boat back in the water with confidence

Pro Tip: Tear the chopped strand mat instead of cutting it. This technique preserves the length of the fibers along the torn edge, resulting in stronger bonds when layering the material
