Maybe I'm missing something, but when welding costs only $.50 per pound of welding rod...and adhesives cost, well, much more than that, I just don't get the advantage of using a high dollar epoxy on steel.
Now, that said, I do understand there there are advantages to bonding modern aluminum panels, because welding AL is more costly than welding steel. And, all of the modern plastic panels must, of course, be bonded. My 2005 Jag has many bonded panels, but the whole body is AL...apples to oranges comparison to our steel TR's.
Asside from the technical aspect, it just makes financial sense to weld a steel body.
