This is a Metal Epoxy.
Quoting from the package:
The City of Dallas, Texas repaired a cracked Caterpillar
engine block with J-B Weld and saved $4,000.00 plus 30
hours down time.
We are city folks who don't believe everything we read
and don't have much experience with bailing wire.
But we recommend this glue for some applications.
A Kansas farmer said, "I have used J-B Weld for more
than five years on my farm equipment and I have decided
that it is even better than bailing wire."
