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. AutoWeld sets in 5 minutes and after 60 minutes, can be drilled, tapped, machined, ground, filed and painted. AutoWeld cures to a dark grey color, is rated at a tensile strength of 900 PSI and will withstand temperatures up to 300ºF.
