Rick, it's been a while for me, but the main issue I recall was expansion/contraction, with the envelope heating or cooling at a rate that the glue couldn't match, resulting in cracked tube or broken seal. It's been a long time though, so I really don't recall the particulars.
JB Weld is used on engines and other high temp applications as mentioned, so it would probably be fine. I run 810s as modulators and they do get hot, but I doubt it would be an issue. Sometime somewhere, YEARS ago, I had the formula used by RCA for this purpose. Maybe I'll find it during the move?
