I weighed out the resin to give a 50/50 resin glass ratio and applied with a roller.
Followed this with peel ply etc and put between to panes of plate glass with 3 layers of bricks on top.
Once fully cure the laminate just peeled off the foam as I took the peel ply off.
(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.
