An easty to use 2-part resin/hardener system for quick repairs, tooling and general bonding. This is the stuff we use for minor paddle repairs in the shop. Bonds to wood, fiberglass and metal. Can be used in spot applications to hold parts in position while standard epoxy bonds cure. It can be modified with West System fillers. Kit includes two 4 oz bottles: one of resin, one of hardener; mix one-to-one, no pumps required. Cures in 3-5 minutes.
