Make strong, lasting repairs with the adhesive power of Gorilla Glue. It expands into gaps and other openings as it dries, creating a durable and waterproof bond between pieces of material. Use this glue with a variety of materials, including metal, wood, and ceramics. It's useful for mending broken items as well as modelling and other crafts. The polyurethane adhesive dries quickly for a permanent bond. Once dry, you can finish with paint, or stain.
