There is a resin for rotocasting available in San Francisco...it would mean a trip out there. I will eventually need it for my General Ursus helmet...I will use the leftovers and try to replicate those ape-o-naut helmets, and just have someone else vacuu-form the glass part of the helmet. I would need to make sure the base of the helmet sculpt is large enough to fit over Zira's hair...or just re-do her hair entirely...perhaps that would be the way to go...but someday I will get this done.
