If treated with this adhesive do we know that it will last over a decade (and if so how much) without breaking down and or failing in some way?
Also, some good tubes were coated with VacSeal that IIRC is known to be ineffective...Can this apply to those CRTs too?

Well this is just alumina and silicate. It's hard to imagine it breaking down to any appreciable degree given that it is essentially just a "paste" of rock. I do think the biggest threats to a tube treated with Peltron would be water and the solutions of acids or bases, but I can't imagine anyone taking their 15G with them for a swim so that's kind of a moot point.
Of course a low humidity environment for a successfully sealed tube would be advantageous, but given the propensity of the ultor flange to rust, low humidity has always been ideal.
