From this first site I got a good price on Carbon fabric with great service

From this second site I got 3.2 fiberglass(they call it 3.1) Satin weave (4HS) that drapes and shapes easily, with great service and price. With this E-glass, I will use multiple layers, more glass and less epoxy will hopefully equal reasonable strength and weight.

Has anyone used 3 - 4 layers, sand into the top layer and then use fill/skim coats to smooth it all out? Thanks - Chris

: I used Raka's 3.25oz tight weave on my last boat - open cockpit Eider from
: Shearwater - fun boat. I was concerned about weight because I wanted be
: able to throw it on the roof rack by myself. The 3.25 oz worked like a
: charm. The tight weave is a bit more difficult to wet out - but you will
: get the hang right away. I would highly recommend a sealer coat of epoxy
: on the wood before you glass. You can pretty much tell the parts where I
: glassed on wood vs. epoxy. I had problems getting the fabric saturated on
: the try wood sections.

: The 3.25 oz takes very little epoxy to saturate and only 1 to 2 fill coats to
: get a level finish. The stuff appears to be extremely strong too. One day
: my brother, myself, and two dogs - probably close to 600lbs were paddling
: on a lake submerging her just about to the deck. We scraped over a
: submerged rock going about 6 knots and we had nothing but a scratch into
: the epoxy to show for it. I was pretty worried about strength since I
: built her out of Home Depot 1/8" Luan. But I put a layer of glass on
: both sides of the flat panels before stitching - then another layer inside
: and out and yet another on the bottom. She is light -
