It might be worth looking into vinylester for the same reason. It has similar mechanical properties in terms of elongation. And I suspect thinning with styrene monomer would be better than thinning epoxy with acetone, as the material properties should change less.
I can see if I can dig up a reference in my ASM handbook.
Polyester isn't as good, as it is more brittle. Which is why it sands nicely.

Joel Shine, the moderator of this section of the forum, can give you good advice. His business specializes in boat kits with wood/epoxy construction. Done right, it's a good, economical construction method. Or you could post on their forum and ask for advice there ( http://forums.bateau2.com/index.php). There are some good guys over there with experience in wood/epoxy that may be helpful.
