I use 4oz S-Glass. It is strong and light. I roll it out onto the hull the night before so it can warm up with the rest of the space before glassing. I trim it with a two inch overhang. It conforms more easily to the boat shape if there is not too much dry glass overhanging the edges. Here the glass has been wet out. Get the space warmed up, with the resin near the heater, and it is easier to get good transparency and prevent blushing. All fill-coats will be applied to the outside of the hull during the same day for a chemical bond.
