: I made the learning mistake of using 5oz polyster over 4oz s-glass
: for the exterior of a Chesapeake 16 s&g. I read that it was
: a poor mans replacement for kevlar in vacuum bagged applications
: so I went with that idea. For hand layups it soaks up TOO much
: epoxy. Pretty sure I added about 8lbs from that one layer.

I use a lighter weave polyester all the time and I find it very difficult to get any epoxy into the fabric at all. I wonder what polyester you used and how much the fabric bulks. Of course the polyester I use is the first layer in the layup and not one in the middle or on top, shouldn't matter though.
