This premium 1 oz fiberglass chopped strand mat comes in a continuous 3-yard by 50" roll, engineered for hand layup, vacuum bagging, and molding with epoxy, polyester, or vinyl ester resins. It delivers uniform strength and stiffness in all directions, conforms better to mold details than woven roving, and builds thickness at approximately 1/32" per layer, making it ideal for marine, transportation, and construction applications.

I used product to repair my pond prowler plastic boat that sustained a hole in the aft due to fire. It was my first time making such a repair and I must say it turned out great. The holed was patched and easily sanded. I painted it and was back on the water with a complete waterproof repair. Thumbs up
