My dad's favorite glue was Aerolite 306, I used to use it a lot in the boat trade. Its a good glue & economical if you use enough of it. If you dont use it up & it goes past its use by date its not so economical! Its still used for aircraft construction & i like using it for wooden masts & spars as its UV stable.
In my experience UF glues have a lifespan of approx 30 years after which they begin to fail, damp conditions can accelerate this.
I have seen early cold molded with uf (laminated) boats & quite a few glued clinker ones that were suffering from general failure everywhere.
Then epoxies such as West & SP systems became the norm. More versatile & stronger but with the big drawback that they are not UV stable & will go gingery & fail if exposed to strong sunlight.
A couple of years ago I used a two part liquid UF glue from Glues Direct for vacumn bagging veneer, it was very good but the shelf life was 4 months before it went off so i wont be using that again in a hurry!
