Epoxy seal coat or just apply the glass over the raw wood? Previously, I've just laid the glass fabric over well sanded wood and worked the epoxy into the weave. On a few occasions, I've encountered areas where the wood is thirstier than others, and when I've come back to check I've noticed a few white spots that I've had to scramble to correct. So I'm wondering: if I seal the wood with a coat of epoxy (which would have the added benefit of allowing me to sand very smoothly before applying the glass), would that overcome the problem of uneven absorbtion? Would the glass adhere just as well to an undercoat of epoxy, or am I better off with the initial glass-bonding coat of epoxy being able to penetrate into the wood fibers? The extra time of applying a seal coat is not an issue for me; the only question is: what will produce the better result? Any advice?
