JB Weld Works

I have used JB Weld for decades, a very good two-part epoxy. Drills and sands easily. This is the biggest size I have seen and is a great value for the money. Works great in metal, platic and even wood.

Seemed to work very well. Repaired a washing machine drum that had almost rusted through. I sleeved the center post with a thin pipe then filled the inside of it with J.B. seems very strong now.

This stuff is the duck tape of glue. It literally fixes anything. Candle broke? Jb Weld. Trashcan broke? Jb Weld. Car sidewiew mirror fell off? JB Weld. Porch rail wobbly? JB Weld. Kids won't stay in bed? JB Weld.
