Hi Jose,
Yes, I used #2113, a 2.3 oz material for re-enforcing on the bottom, 2 layers crosswise to the canoe. 2113 has a breaking strength of 195 lbs in warp and 75 in fill, it's layed so the 195 lbs is across the canoe.
There is also 2 full layers of #7516, a 2.85 oz material with a strength of 205 lbs warp and 145 lbs fill.
The bottom has a "combined" strength of 560 lbs lengthwise to the canoe and 680 lbs across, the sides are 290 and 410 respectively. This is per side, in and out.
Std "6" oz is 220 lbs by 220 lbs.
As for the wetout, yes, the 2113 is difficult.
I also used it on the last project, 4 layers in and out. I use a nylon brush to wet the cloth, working the resin in a bit at a time. I used System 3 Clear Coat, as it's the least vicious resin I could find. Only mix about 4-6 oz at a time, as it changes properties before you can get it all on, and then it doesn't wet out very well, it has to be fresh.
If I could come up with system to roll the resin on and then lay the glass, that would probably wet out much better and use less resin. I used too much resin on this wetout, it's very easy to put on too much with the light cloth, I went to wetting 2 layers at once to reduce the floating.
The cloth conforms to the hull OK with a little rubbing at the "off" angles, like std cloth does, it just takes a bit more work.
As for Thayercraft, yes, they have very good prices. I bought a roll of each weight for just a little more, maybe $50, then buying what I needed from other sources. But now I have enough glass for several more projects.
Also, what I got was very nice material, full rolls in unopened manufacturer's boxes. It is a bit old however, so keep it sealed, I think I read some place that the coating they apply can "evaporate" off if it's exposed for long periods of time, ie, greater then a year say.
AND he shipped me the glass almost the same day I called the order in and billed me later and excepted a personal check for payment.
He only sells either full rolls or small pieces though, the small pieces mainly on e-bay.
