I have two sheets of "rubber" -- ea approx 6x12" -- that I would like to
bond together (face to face) AS IF they were a single sheet. I.e.,
6x12" but thicker.

"Rubber cement"!

But, last time I used this was in grade school and I don't recall
using it for *rubber*!

Nor do I recall it as being a particularly strong bond! OTOH,
I (belatedly!) understand that such an adhesive needs to be flexible
(at least in some applications -- mine) and not brittle!

I'm concerned primarily with shear loads, vibration, temperature
extremes (-30F -- +130F), moisture, etc.

Does "rubber cement" have these characteristics? Was my childhood
exposure to it just driven by some *other* "advantage" that it
had, back then (cheap, safe, etc.) -- considering the uses a
kid would have for it wouldn't tend to need "strength", durability,
etc.

You want contact cement . Try to get the solvent based , the latex stuff (at
least in years past) is junk .

My experiance has been that contact cement softens and fails at higher temps.

Try superglue on a sample. I have had good results with it for several rubber
type compounds.

There is a product called "last glue" - very much like superglue, but
designed for bonding "O"ring material etc. I've never had any luck
with "crazy glue", but this stuff is FANTASTIC.. Bonds virtually
anything to anything and is not a "brittle bond"

Would be interesting to know how thick the sheets are, how much
bending/flexing
is needed and what's the consequence of failure.
Off the top of my inexperienced head, wouldn't vulcanizing be a better
choice than trying to glue something that's flexing?

Half a square foot of rubber sheet can't be all that expensive.

How thick are these sheets? Maybe you could try sewing them together.

Clare's suggested product - a new one on me - but sounds good.

My first thought was the rubber cement used for patching inner tubes.

Also - an old web site was once dedicated to gluing -

I've used this stuff for closed cell rubber pipe insulation. It works for all kinds of rubber stuff like rubber sheet insulation. Johnstone Supply and other HVAC supply houses sell it. ^_^

Visited a larger, well stocked hardware store this morning. I.e.,
they have a "glue aisle". After reading labels, selected what *I*
thought would be the best product.

Sales droid, unaware of my selection, then selected the same
product.

Tried this on returning home. Perfect! Those pieces will never
be coming apart, now! Though product claims it should cure for
many *days* (WTF?!).

Having *finished* the job, read the label more thoroughly and note
that it calls itself a "contact adhesive". (sure dries *fast*, though)

Thanks, again!

I used to use "Plyobond" for a lot of that kind of use, years ago.
Not sure if it is still available. Found it was tougher than Lepages

Nicknamed "bitch-a-thane" ...Window Wrap® Butyl is a self-adhering,
self-sealing 25-mil flashing tape for sealing around windows, doors,
and building joints. With proper application, Window Wrap® Butyl will
prevent water leaks, air infiltration and reduce noise. Window Wrap®
Butyl consists of a butyl rubber adhesive which is laminated to a
polyethylene film. Flexible at low temperatures; stays pliable to
maintain a tight seal. Black film surface. Adheres to most building
materials including plywood, OSB, house wrap, concrete and most
metals.

Once it was mistakenly overlapped and stuck to itself -- just cut
another piece

Tough stuff. Expensive, too.

You can buy plastic sheets (don't know about rubber o_O) over the
internet, which is better than buying them at a retail outfit.
Especially when the lady at the register gets on the PA and sez: "Can
anyone in bedding check the rubber sheets, king size, please!"

"contact cement"

IMNSHO, things like rubber cement and contact cement are basically the
same solvent(s) at different concentrations and with different amount of
thickeners.

I recently needed to bond some rubber, and not having anything
appropriate, I used an already opened can of plasti-dip (which has a
very strong solvent stink). The rubber stuck to itself very well, but
in the future I would like to do some experiments and try to figure out
which specific solvent(s) are the best to use for rubber.

We already know that tetrahydrofuran is the cat's pajamas for vinyl (and
PVC) applications, now we just need to figure out what rubber wants.

It will depend on what kind of "rubber" it is - - -many kinds of
synthetic rubbers, and different concentrations of natural rubber
mixed with them - -

This is true; for my application, the rubber in question was a section
