Just to clear up my mind .... Are you saying that if you paint PVA release agent onto a layup on V/E or P/E resin it will make it dry better??
V/E does have drying problems, it stays tacky for some time, Does PVA help this. ++++++++++++++++++++ PE and VE resins exude a gum to the surface (surfaces?) when curing - this is the perceived tackiness (that takes ages to dry out). I once used a high quality PE that had reportedly been "de-gummed" and it was very nice to work with and sand, like fast curing epoxy. A US manufacturer for model airplane products (K&B) also offers something similar that I have used. The big difference is in how the cured resin will sand, the gum quickly clogs up the paper and that is a real pain. I am also interested in the comment regarding PVA as a potential solution, but what are we talking about - PVA wood glue? PVA water soluble release agent? PVA wall paint? Steve J
