Looking in Bunnings I see we have Gorilla Glue which is pretty expensive. Is there anything else which works well for joining foam to foam? I tried a polyurethane construction adhesive and got a dissolved mess from the solvent, on test pieces.
For sticking the PMF we have good old waterproof PVA which is our version of Titebond 2 I think, so that's easy and cheap to get.
Cheers!
