I've thought about that, but how is it for creep? My impression is
that UF and epoxy are better in this regard. But maybe that's

SFWIW, For the price of Gorilla Glue or equal, you can add maybe 10%
and get epoxy.

There is no comparison between epoxy and Gorilla Glue.

Thanks, Lew. I wonder what the trade-offs are between UF and epoxy?
Sounds like you are a "fan" of epoxy, but there are always tradeoffs.

Lew LOVES epoxy (and must have stock WestSystems). He suggests it for
virtually every fix where an adhesive is used. Since he works on boats,
its
a natural choice. For the rest of us, we get to use several diffrent
glues.
And his love of epoxy may be well founded--in its many formulations it
is wonderfully flexible. But I still believe that there are tradeoffs
in selection of any construction material or technique, and I'd like
to see some discussion to form the basis of an informed choice.

Cagle, in "Handbook of Adhesive Bonding", a well known engineering
reference, recommends UF or RF over epoxy for wood-to-wood joints exposed to
weather. I don't remember why now and my copy is not readily accessible.
However he was writing over 30 years ago and the available epoxy
formulations may have improved since then.

Personally I generally use Titebond or PU for the convenience, but if it's
mission-critical indoor and I've got a good fit I go for the UF and
mission-critical outdoor the RF.

OTOH, I've got an assembly I'm going to glue up with T88 epoxy tomorrow, the
reason being that it's outdoors, the temperature right now is going down
into the high 30s at night, and T88 will cure at that temperature
(eventually) while UF and RF aren't rated to cure below 70 and the rest not
below 50.
