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.
