Pretty fascinating nine-minute video on JB Weld being put to the test on structural steel. JB is really impressive stuff.
Interesting video on JB Weld test on structural steels, took 4+ tons of pressure to bust- Destructive test, simulation and review

One of the few PF tests he qualified for. Glue the same material with various glues - stack weights to failure …
JB Weld did good …
I had an ‘83 1.6 Ford Escort for a couple years that had a surface imperfection (crack? missing chunk?) in an aluminum head, visible under the valve cover, that was repaired with JB Weld (or similar epoxy, I didn’t do the repair). Amazingly it lasted the whole time I owned it-it was at least as strong as the Ford aluminum casting!
Prep is so important, but good epoxy is awesome.
I currently have a thread discussing long cure epoxies like JB Weld. Very timely. I have JB Marine Epoxy at home.
JB Weld can withstand 550 F when fully cured.
This cannot be overstressed!
grab a drink and a sandwich.
E-28 gas tanks are prone to rust toward the end. I developed a process using the 1lb tubes. I repaired several using JB Weld Most of the tanks had a drain and they were easy to siphon, so dropping the tank was simple. I put a gallon of water in it and sealed up the inlets and outlets. Then I went to town with a knotted wire wheel, and took away to bare metal the merest bit of rust. The sides and the top where the damp dirt collected had many pin holes clogged by the rust they made, Grind that away, roll the tank over and watch the drips.Too many for spot repairs, a 4" putty knife worked the best. The process was long, I worked on it after supper for a week. A new tank was 250$ plus shipping and I was under employed at the time. I probably broke even. The desired result was an interior that didn't smell of gas and it worked every time. It works even better with aluminum too. Just follow the directions. Happy New YR
