No problem. I don’t use any PVA bags directly on my foam. After shell is
ready for lamination, mix needed amount of sealing resin (siegelhartz)
with a few drops of acetone (this will thin the sealing resin enough to
not allow tear drops forming). Paint over foam form, after drying, sand
lightly with water-paper (without the water). If you don’t intend
removing the foam, laminate directly on the foam. If you do intend
removing the foam, place PVA bag on now and continue as usual.
