One last comment; fiberglass isn't much lighter than thin steel panels. Glass
and resin are heavy and typically thick. The Al panels are a plus. "Carbon
fiber" is really carbon fibers set in a resin. The advantage is that carbon is
light and there is very little resin because the panels are super thin and
therefore, light. Two cents please.
