Everywhere I used 30NF (sometimes with questionable results and long dry times) I could have used epoxy for the same price.
I try to do all gluing before sealing or finishing, especially for wood and wood glue. Where I did not want glue splotches spoiling the wood finish, I either masked extensively or scrape/sand very well before staining.

And CPES as a primer? That seems to be the wood boat regimen.

Someone else chime in with a different experience, but I've tried to glue plywood to both extruded and expanded polystyrene foams with TiteBond II, and it certainly did not work.
On the other hand, I've tried different polyurethane glues and foamboard glues, and they worked well. The polyurethane glues required a light misting of the foam; the foamboard glues required several hours of clamping pressure and lots of air drying time.
Sure made me wish I had a 4x8 vacuum bagging system
