The guys down my street who build log tables, beds, etc, use nothing but Gorilla, admitting that they had tossed everything else out (poured it into sawdust, let the lump set up, out everything went.)
I've not needed to glue up anything in my wood sculpting until the next project ( a pair of 75cm Ravens with add-on beaks). All these testimonials have me convinced.

Just a couple of considerations I shoulda mentioned when using Gorilla Glue. First, unless the missus doesn't mind you having black resin coated hands, wear gloves (I use the cheap latex ones which I buy even cheaper on ebay. A box of 100 lasts quite a while) & second as Gorilla Glue reacts to moisture when curing it's a real good idea to keep the nozzle sealed air tight when storing or you'll go back to use it & find you've got a solid mass instead of runny honey-like glue. Just saying.

apauly and others:
How well does Gorilla Glue hold up in carvings meant to be left outdoors in the elements?

I'd say it would be absolutely perfect & would not deteriorate at all. I base this on the experience & knowledge that one of my fellow wood surfboard builders (in Noosa, Australia) uses Gorilla on his Paulownia boards & as Paulownia does not absorb saltwater he doesn't even bother to seal them. Just a light oiling with raw linseed.

That's good news. Still doing outdoor summer things but hope to glue the beak blanks to the birds soon to post as a WIP. Gorilla glue it is.

AV Syntec (an Oz company) make a wood friendly polurethane glue that has over the past 10 years of so of outdoor exposure in my yard bench has proven much superior to Gorilla Glue in holding things together - I ran out of the local product & used Gorilla to finish, the Gorilla has failed but the local product is still going strong.
