Thinking out loud here... the carbon being porous could be laid between the skin and foam on a foam core wing. I love the polyurethane glues for skin attachment. The PU glues should foam right through the carbon and bond everything. With the tissue on top this should be a supper strong skin.
Thank you

Ken,
I am personally not using carbon veil at all. Matt K had done it both ways. He has put it under the balsa skins on foam core wings and has also applied it on top of the balsa sheeting with silkspan applied over the carbon. He does this for strength from the carbon and the silkspan gives a smooth paintable surface.
