With respect to having too little epoxy in
the layup, we had some repairs that were
done by someone else on our control surfaces.
Apparently peel ply was used without wetting
it out. The resulting glass was white in appearence,
and in places, could be peeled off, almost as if it
were peel ply. I believe that dry peel ply starved the
layup of epoxy. We ended up having to wet the layup
out again, with wetted-out peel ply, to get the edges
to stick.
In my opinion, if peel ply is used, wet it out, do
NOT leave dry peel ply on a layup.
