Robert,
The skins are just 2 layers of 200-gram cloth on most of the hull on each side of the foam. With the vacuum bagging the layers were compressed and the resin drawn through the lay-up but I understand your concern without vacuum bagging, a very thick resin, or a thick lay-up I could see it as a problem.
The resin with 407 in the picture was painted on the hull, carbon laid, squeegee, and next layer carbon lay-up, wetted out with straight resin, squeegee, and bagged.
I'm laying-up Saturday if you want to see the process extra help and thoughts are always welcome! We have a good time and grog for the crew once the work is done.
