I think I'm not going to get enough of the heel to conform to the mold unless I vacuum bag it or make a two piece mold.
It'll be easier for me to make a two piece mold. I can just layup some fiberglass on top of what I've already made. What I want to know though, is should I first layup some gelcoat and then also coat that with wax and pva? This would take up some space between the two molds so there will be room for the carbon. Or will the carbon compress enough that I can take two identical molds and sandwich it between? I suspect it won't be a great fit that way.
