J B 8277 Water Weld
Water Weld will plug or seal practically anything that leaks. It will patch holes and cracks, and mend almost anything that is broken. It is excellent for rebuilding or fabricating parts, and as an all-purpose adhesive for metals, wood, fiberglass, masonry, ceramics, PVC and ABS. Permanently repair holes, gouges, cuts. Seals rot in fiberglass and wood. Safe for use on lines carrying potable water. Plug holes and make permanent repairs under water and in gas tanks while they're still leaking. Packaged in a single cylinder, you simply cut off as much of the material as you need, twist and knead with your fingers, apply immediately to surface to be repaired. Stays pliable for about 2 minutes after mixing, sets in just 20 minutes, and cures fully in just a few hours. Bonds to virtually any combination of iron, steel, copper, aluminum, brass, bronze, pewter, porcelain, ceramic, marble, glass, PVC & ABS, concrete, fiberglass, wood, fabric, paper -- just about any porous and non-porous material.
