Has any body here ever used pink wall plaster to make a fibreglass mould? I'm using the blue foam used in model making and taxidermy, then sealing it with PVA and fibreglassing over the top. At this point I'm only looking at making one so I don't need a reusable mould. Whats the best thing to use as a release agent to put on the plaster mould when I come to laminating the new part?
