Star brite Epoxy Aluminum Putty Stick 87004 - Underwater Repair for Aluminum Boats, RVs, Tanks
Star brite Epoxy Aluminum Putty Stick 87004 - Underwater Repair for Aluminum Boats, RVs, Tanks
Star brite Epoxy Aluminum Putty Stick (87004) is a kneadable two-part epoxy formulated specifically for repairing aluminum surfaces, and it can be applied and will cure even underwater. It is designed for aluminum boats, RV bodies, fuel tanks, gutters, and storm doors, making it a practical fix for hull dings, pinhole leaks, and damaged fittings without hauling out or draining a tank first. The high-density formula bonds within minutes and continues curing to a steel-hard finish, and once fully cured it withstands extreme temperatures and pressures, so it holds up in demanding spots like exhaust systems, manifolds, and other engine-adjacent components.
The putty is simple to use: knead the epoxy resin stick by hand until the color is uniform, then press and shape it directly onto the repair area, even below the waterline. After it fully cures it can be sanded, drilled, and painted, so a repair can be blended into the surrounding surface rather than left as a visible patch. Each stick contains 4 fluid ounces of silver-colored epoxy resin putty, sized to fit in a repair kit, tackle box, or emergency toolkit for on-the-go fixes. Because it is aluminum-specific, it is a better match for pontoons, jon boats, canoes, and other bare or painted aluminum surfaces than a general-purpose epoxy putty.
