Yeah, I thought I'd covered it to be honest. A good coat of PVA, a decent layer of tile grout bonded with PVA, and a few layers of paint. Must have been some pinholes in it somewhere.
The surface is unaffected so I could live with that, and it dries lovely and clear (the lighter discolouration is from a previous PVA pour test), but my main concern was that if it ate the foam like that, what would it do to a plastic model half submerged in it! :flushed:
