Fiberglass vs. Fabric

Thanks, I did layer up the other side and was quite suprised of the
stiffness. So far every piece will be flat, then cut to size and
glassed together, so it seems to be working out. Unfortunatley it's
been just under 70 deg. around here and especially in my basement so I
bought some 2 inch foam and a small heater. I made a make/shift oven to
help cure the fiberglass. I happen to have a remote thermometer inside
to watch the temp. It's been working out great.
