Use to fix, bond, or fill-in the shop, factory, or field. Can be formed, drilled, ground, tapped, machined, filled, sanded, and painted. Includes two tubes. One contains liquid steel/epoxy resin, and the other contains hardener. When mixed together in equal portions, a chemical reaction occurs that turns the mixture into a compound as hard and tough as steel. It stays pliable for about 30 minutes after mixing, sets in 4-6 hours, and cures fully in 15-24 hours. It's waterproof; petroleum, and acid-resistant; resists shock, vibration, and extreme temperature fluctuations also withstands temperatures up to 300° Fahrenheit.
