J-B Weld Marine Weld Marine Epoxy, 56-g

MarineWeld™ is a specially formulated two-part epoxy cold weld system designed for strong, long-lasting repairs. It effectively bonds different or similar surfaces, including aluminum, metal, composites, fiberglass, and more. MarineWeld™ sets within 4 to 6 hours at room temperature and cures fully to a dark grey colour in 15 to 24 hours. Once cured, it can be shaped, tapped, filed, sanded, and drilled, maintaining its strength whether above or below the water's surface. MarineWeld™ has a 1:1 mixing ratio and a tensile strength of 5,020 PSI.
