PEEL-N-SEAL is perhaps the most versatile, easy-to-use, durable repair material in the world! Simply peel off the film to expose the sticky resin, apply it to the prepared surface needing repair and expose to sunlight or a UV light source. PEEL-N-SEAL will cure in about 10 minutes to a rock-hard, durable, corrosion resistant surface that can be sanded and painted or left as is. Additional sheets can be added for virtually unlimited strength! For use inside, an artificial UV light source will be required.
