I was unable to find a difference in weight between a 2' x 2' sample of
each, this was using a postal scale accurate to .1 OZ. That said after
finishing, painting each system there might be some difference, but I would
think that it would be very small.

Good Luck

Doug, thanks. You said that the 1.4oz is close to fabric in weight. Is
that finihed weight
with the epoxy against finished weight of fabric all doped up?
