Curious, have you done much layup work?

If I had to dream up the most difficult glass project I could come up with, a rifle stock would probably be it.

Tight radiuses, near right angles (you can't do true 90 degree angles)...

I think even a expert at layup would have difficulty wrapping something the shape of a lower. It would be much easier with a chopper gun- but that isn't in the cards unless you have a shop nearby.

I would use very light cloth because of the geometry- and get the build from multiple layers of epoxy resin, even adding a filler to increase build.

If you use regular styrofoam, acetone (proper safety procedures) will dissolve the foam out after the glass cures.
