Silane for resin/silane for epoxy
Curious to know if anybody has ever used the 3/4 glass from thayercraft they have listed for resin rather than the smaller, narrower glass listed for use with epoxy.
What is silane? Is it simply a wetting agent or similar?

Looks as though it does strengthen Jim
From the link David provided :Finishes are put on glass fabrics to allow a strong bond between the resin and the glass. If you take a sheet of glass and put resin on it, let it cure then try to peel it off it will easily come off, or chip off. Finishes like Volan or Silane act as intermediaries between the resin and the glass. Volan has been around a lot longer than the Silanes but I think is still one of the best finishes. Volan is generally the softest finish with the exception of some Silanes.

All of the above is correct. I don't think silane could be called a wetting agent in the same sense as soldering flux, it's only purpose is to increase bonding strength between epoxy and fibre. If it does help with wetting, that's only a fortunate side-effect. I have not researched this aspect, so can't really comment if and how much effect it has on wetting properties. All of the fabrics that I am aware of are treated with silane or some equivalent stuff.
