' The skins are stiffened and sealed with laminating (thin) epoxy on the inside. I rub off as much as I can with paper towels. Enough remains to stiffen and seal the inside surface. Each stab skin gains about 1 gram of epoxy from this treatment. '
Hi Matt,
Would you consider .2oz carbon veil on the inside instead - is lighter than absorbed epoxy and adds more tensile strength across the grain. It would help with confidence re the sanding of the sheets .
