If a novice can try to reconcile a couple of opinions here, I think
that everyone is correct.  The older guys involved in manufacturing
and production didn't care for hot glue because it was not great to
work with.

They were not concerned with restoration.  The restorers like it
because it makes it easier to take things apart to restore.  So they
are both right, it just depends on where you are coming from.
