Steelstik is a hand-mixable, steel-reinforced, non-rusting epoxy putty that quickly repairs or rebuilds anything made of metal. After mixing, it forms an industrial-strength polymer compound that can be molded into shapes or used to build up, patch and repair steel components. Steelstik sets in 3-5 minutes and after 60 minutes, can be drilled, tapped, machined, ground, filed and painted. Steelstik cures to a dark grey color, is rated at a tensile strength of 900 PSI and will withstand temperatures up to 300 degree Fahrenheit. THE ORIGINAL COLD WELD: JB Weld was developed as an alternative to torch welding. Designed to be effective in extreme environments, once it sets, it creates a permanent bond stronger than steel.SIMPLE TO USE: SteelStik sets in 3-5 minutes. After 60 minutes, can be drilled, tapped, machined, ground, filed and painted. Curing to a dark grey color, it is rated at a tensile strength of 900 PSI.VERSATILE & DEPENDABLE: Ideal for automotive, brick, ceramic, concrete, metal, underwater and wet use, exhaust systems, plumbing, stripped threads, rust damage, household repairs and more.DO IT YOURSELF: Big or small, you can DIY it with J-B.
