"An easy to use, 2-part resin/hardener system for quick repairs, tooling and general bonding. May be used in spot applications to hold parts in position while standard epoxy bonds cure. Bonds to wood, fiberglass, and metal. Not recommended for long-term bonds subject to high loads or moisture. It can be modified with WEST SYSTEM fillers. One-to-one mixture, no pumps are required. Cures in 3-5 minutes."
