I'll look into contact cement. Gene also suggested that. Cost is not so
much an issue but shelf life after opening is. The usual rubber cement
is toast only a few months after opening.

It also has to become a pliable connection because those cuts are on the
side walls. Ever since moving to tire liners plus thich tubes plus thick
tire surfaces I don't get "regular" flats via running surface punctures
anymore.

A useful tip for storing cans or bottles of such materials (including
paints, as well) is to store them upside down.


Good point. At least I always make sure to turn them upside down for a
little and then right them again. That way any possible break in te seal
will (hopefully) remain "gunked".


That way, any slight imperfection in the seal around the lid will fill
with the glue, paint, or whatever, and dry to form a perfect seal,
which will preserve the contents.


Except that continued upside-down storage without a catch basin can
result in a nasty surprise when coming back from a vacation.


If you store it right side up, only the vapour will be seeping out of
any imperfections, and the contents will dry out.
The only downside is that it can get difficult to open, if the seal
was particularly bad to start with, as the glue or paint will stick
the lid on rather firmly. But that only happens in the case of a
container in which the contents would have dried out anyway, so you
haven't lost anything.


I got used to the fact that PVC cement, various glues and whatnot can
require a vise and sturdy pliers to open if it hadn't been used for a
few months. No big deal.
