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 buildup, patch and repair steel components. SteelStik? sets in 3 to 5 mins and after 60 mins, can be drilled, tapped, machined, ground, filed and painted. SteelStik? cures to a dark gray color, is rated at a tensile strength of 900 psi and will withstand temperatures up to 300 deg F.
