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 Doris Tran

This product dries like a matt colour/texture chopping board. Not very smooth but good for separating the epoxy and washing the material off in one wash. I'm sticking with at least a 3 layer High Air Low product mist which works best. Adding a 50% dilution with water will increase the smoothness of the straightener, but will still dry to a matte finish. Maybe some Teflon additive or silicone will help to give it a shiny finish. I don't know, but it's a good opportunity.
