Bent glu-lam red/yellow cedar for outdoors

I had posted earlier about a large 6x6x19' (10' radius) bent laminate
beam project, using 1x6 lumber stock.

Since then, I have managed to find a reasonable price on green 1/4"x6
red and yellow cedar, which will bend just great without having to
steam them.

Now I have to figure out what glue to use, and any other treatments to
be applied to the finished beam.

This will be for outdoor use (Pacific Northwest rain!), and I want to
show off the wood as much as possible.

Best glues I've heard of so far would be Titebond II and Gorilla Glue.
I don't know about sealants or stains.

Any tips or suggestions?

Thanks,
Dave

Creep resistance of the glue is very important for curved laminations,
as is long open time and a truckload of clamps. I would use West
System or other marine epoxy. More info:

I second the use of slower setting epoxy.

Epoxy joints don't like being clamped really tight , sometimes I use
masking tape for clamping curved shapes , it works great

Not too sure about using epoxy (or anything else) on green wood,
Gorilla glue is activated by moisture so may stick better, probably
has some give to it as well, it's pretty rubbery.

Once dry?...finish with a Sikkens product, or epoxy coating. I live
on the western slope of the Cascade mountains, I have a Lindal Cedar
home....you understand...:)
