Mike,
The molds were perfect, polished smooth as glass, but I had no experience spraying gelcoat so I didnt do it.

At the time, I was looking to pull hulls out as quickly as possible and decided I would worry about it later.

For a brief moment I toyed with wood veneer, http://www.rockler.com/rockler/images/Walnut-1.jpg
and also toyed with leaving it clear coated carbon, but was talked out of both ideas because epoxy softens when it gets too hot and both finishes would have gotten hot in the summer sun.

My thought was that the wood veneer would actually add strenght to the hull as well as provide a finished surface. But then the wood veneer would have to be clear coated, and that would add weight, so I discarded that idea.
