J-B MarineWeld is a specially formulated two-part Cold-Weld adhesive system that provides strong, lasting repairs for bonding different or similar surfaces, such as metal, composites, fiberglass and others. MarineWeld sets in 20 mins at room temperature. At full cure, its color is white. It may then be shaped, tapped, filed, sanded and drilled, retaining full strength above or below the water surface.
