I was able to use some wood flour to thicken the epoxy and then spread it over the area. Once I covered the area I put the foam core over it and weighed it down with various objects. It's hard as a rock now and has the same shape as the bow. Once that was good I taped/epoxied the edges and then layed a piece of cloth across the whole piece of foam (with extra to go oveer the sides) and I am pretty sure I could jump on the bow now but I'm still going to put in some vertical supports while the boat is upside down. I don't want to have to flip this thing again.
I'll try to grab pictures of the work for you guys. I should be finished with the glass work this weekend.
