Fair enough. This eplains.
This being said, I have used both peel ply and Dacron. Dacron is
definitely harder to remove, but that is not much of a concern. The
surface they leave may be pin hole free, but not exactly smooth, since it
is a negative of the canvas structure, and canvas is not really flat.
I suppose when you make a wing, you would still have some sanding to do
even if you use peel ply. What we would really need would be something
that leaves a gel coat quality finish. At the company I worked for before,
we were producing carbon fiber Unmanned Air Vehicles. The parts came out
of the mold fully finished. Even the camo was there. They painted it on
the mold, somehow, before they laid the fibers.
Just a thought.

The purpose of Peel Ply is to absorb excess epoxy thus reducing the
weight of the lay up. A second advantage of the Peel Ply is the smooth,
virtually pin hole free surface it leaves. A lot of folks also use
Dacron cloth for this purpose. It does not remove as easily as peel ply
so some experimenting may be a good idea. I have heard if you use Dacron
that you want to remove it before the full cure of the epoxy.

I bought some BID fiberglass today in a shop in Paris that sells all
sorts
of composites mainly for artists and designers. I was also looking for
peel ply. The guy had never heard of it. When I explained the purpose,
he
showed me rolls of rigid plastic sheets (looking like old overhead
projector slides). He said that's what his customers use when they want
the cured surfaces to be smooth.
That puzzles me. How come we don't do that? Is it because they fear
trapped bubbles less than we do, or what?
