I can't translate products to USA brands, but I've used epoxy and urethanes-
and I feel urethane has a place in boats. Not saying hulls or wet areas,
but there are plenty of other parts which have moderate strength
requirements, need to be moisture resistant, and are subject to some
movement. Urethane in a cartridge is convenient, gap filling, possibly
dearer than equivalent volume of epoxy, easy to remove the squeeze-out.
Easy clean-up ( except for the brown marks on my hands when I decide I
won't bother to wear the disposable gloves ..... ). For example, my new
engine cover was ply glued up with AV515 urethane. It didn't need the
strength of epoxy, and it was easier to clean up the squeeze-out than epoxy.
It's horses for courses.

Everyone on this NG is aware of the typical adhesives, but I would like
to
alert those who may not be familiar with the 3M 5200 product. This is
the
ultimate adhesive and not necessarily just where flexibility is
required.
This stuff is incredibly strong. It is next to impossible to separate a
glued joint with 5200 without destoying one of both of the components.
It
adheres to everything I've tried steel, aluminum, plastic and wood of
all
kinds. It is waterproof and works through huge temperature change unlike
many adhesives. The dissadvantages are cost, shelf life and long curing
time. As a not, do not use as a sealer, it may work sometimes in that
department, but it is primarily an adhesive.

5200 will NOT bond to copper and does not resist diesel.

None of the urethane adhesives will bond to copper and only SikaFlex 291
can
be used for diesel.

The above straight from application engineering for both 3M and Sika.

As far as glues, etc are concerned, consider the following:

Resorcinol is required for white oak.

Epoxy is the glue of choice for everything else.

After that, it's all down hill.

If the cost of epoxy is too big a nut for you to handle, maybe you should
look for another hobby.
