(Although I think had I primed the foam with resin before the galss was added and/or been warmer it would have made it less likely to delaminate so easily.)

Not really hard to see the problem here in hind sight Phill.

you mixed 50:50 resin.

Lost 10-20% of that into the peel ply
another 10-20% into the foam.

That left you with a resin:cloth ratio of about 30:70.
