2oz at a minimum. I usually lay up the center sections of my wings with 3 layers of 2oz cloth, so I have pieces laying around to use for the firewall.
Bob,
Speaking of glassing center sections, when you use multiple layers of different width (as I think you are saying you do), do you put the widest down first and then work to the narrowest one or the other way around?
