Versachem Radiator and Gas Tank Epoxy is a two-part epoxy stick that repairs leaks, holes and cracks in metal tanks. Use it to plug small holes or fill in seams and cracks without welding or removing the tank. Works best on metal gas tanks, gas cans, other metal tanks, drums, plumbing and pipes. Non-flammable and resistant to gasoline, oil, kerosene and water, with a temperature range of 250F (dry), 125F (wet), and a tensile strength of 920 PSI. For a smooth appearance after curing, hand-rub with water or damp cloth prior to epoxy hardening.
