J-B Weld SteelStik: Steel-Reinforced Epoxy Putty for Metal Repair

J-B Weld SteelStik is a hand-mixable, steel-reinforced, non-rusting epoxy putty designed to repair, rebuild, or patch metal components quickly and durably. It sets in 3–5 minutes, cures to 4,000 PSI strength, and withstands temperatures up to 350°F and water pressure up to 500 PSI.

Use for a cracked pipe, rebuilding a stripped thread, or filling gaps in an automotive part, SteelStik delivers industrial-strength results without welding or specialized tools.  J-B Weld SteelStik is a two-part epoxy putty that is hand-mixed and applied directly to metal surfaces. Once mixed, it forms a polymer compound with steel reinforcement, which can be molded, shaped, or built up to match the original component. It cures to a dark grey color and bonds permanently to metal, aluminum, and automotive surfaces

SteelStik is suited for metal repair across a range of applications. Approved surfaces include:

• Metal (steel, iron, and similar alloys)
• Aluminum
• Automotive components
