J-B Weld 8272 2oz MarineWeld Twin Tube Epoxy

J-B Weld 8272 2oz MarineWeld Twin Tube Epoxy – World’s Strongest Bond

J-B Weld MarineWeld (8272) is a two-part “cold-weld” epoxy formulated for strong, lasting repairs on boats and equipment exposed to water. Mixed at a 1:1 ratio, it bonds aluminum, steel and other metals as well as fiberglass and most plastics/composites. MarineWeld sets in 4–6 hours at room temperature and cures in 15–24 hours to a hard, dark gray finish rated at 5,020 PSI. Once cured, the repair can be shaped, tapped, filed, sanded, and drilled, making it useful for structural patches and hardware mounting. The adhesive retains strength above or below the waterline, and resists water and oil commonly found around hulls, trailers, and engine bays.

For boat owners, marine techs, and maintenance crews, this epoxy provides dependable bonding where standard adhesives struggle—on mixed materials and parts that see vibration and splash. Use it for deck hardware, hull accessories, housings and blocks, shafts and pulleys, and general trailer or shop repairs. The compact twin-tube pack travels well in a toolbox or onboard kit for planned repairs or field service.

Marine technicians value a marine epoxy that bonds metals and composites with time to position parts before set. MarineWeld’s 4–6 hour set gives room for alignment on deck hardware and hull accessories, while the 5,020 PSI strength supports permanent repairs once cured. Because it is water and oil resistant, the epoxy holds up around engines, bilges, and trailers. After a 15–24 hour cure, repairs can be sanded or drilled to match surrounding parts, helping crews finish cleanly without switching products. Facilities and DIY boat owners appreciate the simple 1:1 mix and the ability to repair aluminum, fiberglass, and plastic/PVC using one dependable adhesive.
