Not boat related, but I'm making a plug to make a mould for one of my RC planes. I'm taking one of my smashed up EPP foam airplanes which is just a flying wing, no fuselage or tail. Think B2 bomber. I'm currently sheeting the foam with 1/16" thick balsa, and was planning on using thinned out epoxy over the top of that to kinda firm things up a bit once the whole thing is sheeted, then fairing and sanding from there. Then it would get painted and buffed out. What should the final paint be? Does it really matter as long as its a smooth surface that will release the part, (with wax obviously).

Just a project for the winter, and I've been thinking I could make one stiffer and lighter if it were just a hollow carbon shell. Won't hold up to impacts like the foam one does, but a stick built balsa one doesn't do to well in that respect either.

This is one that is just the foam with some carbon stringers a in it for reinforcement, wrapped in quite a bit of packing tape and then covered in monokote.
