Double stick tape and spray adhesive are both EXTREMELY bad for prints. They'll cause the prints to deteriorate far earlier than 50 yrs.
I'm tempted to report this as a troll. Do you have any evidence whatsoever for that statement? Any data or experience? Or did you just say it because you felt like it?

I'm really tired of people saying that if you don't make prints the way they read about in the Word According to Ansel or something, that your prints will spontaneously crumble in a dramatic burst of accelerated aging at some point in the future (when they don't have any evidence to support that claim).

I, like the OP, an actually interested in REAL information about wet-mounting and adhesive-mounting solutions, and am interested in REAL data and information so that I can make choices about materials. It doesn't help when people just parrot the standard tribal wisdom and wives tales of what is or is not "OMG ARCHAIVAL!!!!!"
