The guilty parties.
We'll be gluing lauan to oak.
Everything all glued--two pieces of each glue type glued to the edge of
the oak, and one of each glue type glued to the face of the oak.
Two test pieces were glued with each glue, and the glues were allowed to cure for about 50 hours.
This should be plenty long for all of the glues except for PL Concrete--it needs at least a week.
However, I've used this glue a lot already, and have a high degree of confidence in it, so I wanted to see how it would hold up if it wasn't allowed to fully cure.
In this picture, you can see that I pulled each type of glue apart with some pliers, and as expected, the glues holding the plies together failed before the PL glues did.

Next I left the remaining glue joints to soak underwater for 7 full days to see if a good soaking would weaken them.
