The old foil-wrapped stuff had a short shelf life, which didn't always keep it from being sold - there were enough roll-off's to make tape illegal for racing (at least in Canada).
If a restored bike is merely on display, why glue at all?
I'm guessing that the 3M product you mention is actually an automotive
trim adhesive; 3M's "FasTack" - a quick-setting glue - was too. It
worked very well, except that the solvent ingredient in Fastack
sometimes negatively-affected the bond between the casing and the base
tape (e.g. Wolber's) and you'd get a roll-off despite having the base
tape firmly glued to the rim....

The adhesive might stick, while the foam between came apart, and leave
you with the same outcome I just mentioned.
Gluing a tub isn't hard: try a few 'dry runs' w/o glue, stretching the tub in the process, and then apply the glue sparingly with a dope brush in successive layers (letting the glue dry in between), which minimizes clean-up (or eliminates it, once you've gotten a little practice).
