Ernest,
I cannot get my mind around your layup of the top of your cowl........You
used the nylon for peel ply (just where you would make additional lay-ups or
all over the top lay-up??)........Also just what was the function of the sleeping
bag ??.....I presume it was under the 2 mil vacuum bag....What was between
sleeping bag and the sticky resin ??............<:)
