Adhesive to fit a board-foam sandwich for fresh water pump

Yep PU glue which I have since used for all sorts of things, gap filling joint between aluminium and wood FI. Did you get the foam offcut I sent BTW?

Thank you, and yes, thank you.

Be careful with PU glue, I had a bottle explode, it felt like it had gone off as it was rock hard. It made a hell of a mess. Now I always squeeze out some of the air, so I can tell if it has expanded.
