Is JB Weld a hole filler or a real metal replacement?
I hear people talking about using JB Weld to fill holes before retapping. Or bonding metals together. What is JB Weld really good for? Is it a hole filler, similar to wood putty on wood? Or is it truely a substance that bonds to metal and is as tough as metal? I used to use furnace cement to fix the burned out fire pots on old pot belly stoves. Is it similar to furnace cement?
What have you used it for?
