Gene; One coat brushed directly to inner surface. As long as the VE has = not had wax added or Air Dry no sanding needed. I have been watching the PVA thread and wondered why go to all the trouble when resin/material = suppliers all carry Air Dry which is especially made to eliminate the tackiness problem and is used for the final lay-up for a smooth slick surface that = is tack free. It just mixes with the resin after the hardener has been = added according to the manufactures proportions and works like a charm and = doesn't clog the sandpaper if later modifications or repairs are required.
