Use J-B WELD as an adhesive laminate plug filler sealant and electrical insulator. Squeeze out equal portions from the black and red tubes. Mix thoroughly. Clean surface to be bonded. Apply J-B WELD and let it cure. That's all there is to it! Like metal J-B WELD can be formed drilled ground tapped machined filled sanded and painted. It stays pliable for about 30 minutes after mixing sets in 4-6 hours and cures fully in 15-24 hours. It's water-proof; petroleum- chemical- and acid-resistent; resists shock vibration and extreme temperature fluctuations and withstands temperatures up to 500° F. J-B WELD is super strong non-toxic and safe to use. Before it sets you can clean up with soap and water.
