The J-B Weld 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 three to five 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 degrees F.
