Review on 🎨 PVA Water Based Mold-Release Agent: Ideal for Epoxy, Polyester, Vinyl Ester, Resin, Gel Coat, Polyurethane Foam. Sculpture and DIY Projects Made Easy - 8oz Spray or Brush-On Film by Dawn Fischer

I bought this PVA because I was out of part PVA #10 and needed something quick. The cork was prepared with partial wax for mold making, the flanges were unwaxed and slip tape was applied to the seams, the gaps were filled with Shavan's plasticine. Pva sprays well. However shortly after applying the tooling gelcoat the PVA started to rise on all areas that had been waxed with partial paste, lifted on flash tape and also on clay. I've spent a lot of gelcoat, a lot of time, and now I'm praying that I can remove the gelcoat without damaging the expensive connector.
