One thing that attracts me to foam factory glues is that they are non toxic. Also a longer cure time than hot glue. Your project will not be "instant."
The 3M90 spray adhesive used in many insulation installations is very toxic and the spray can is labelled with a death warning. Fast cure time, your project is "instant" but VOC's may take time to outgass.
The hot glue had a very fast adhesion, and I had a few melt outs with the foam. Harder to work with larger pieces. Results were " instant."
I will let you know how the foam factory glues perform in my project.
