the board I did unsealed hasn't bubbled (yet), but it was bagged - could be the reason.
Maybe.
Not sealing won't cause it to 'bubble' but causes the laminate to 'drain' as the resin tends to sink into the foam (as it is pourous) particularly with the lighter density stuff.
This results in a laminate full of 'air' and potential pin holes causing water leakage.
I am talking about hand laminating here not bagging.
