So if I did want something more rigid, then the 300 would still be good on the foam? Like on some pink insulation or something like that? Instead of doing the fiberglass resin thing?
Out of curiosity, what happens to it with out PVA as a primer? It just peel off, or does it mess the foam up while cuirng?
