Alternative to molds, and maybe even cheaper!

This guy makes his molds out of 10 layers of fiberglass. im thinking ,aybe you can do this to a helmet and smoothcast the inside. Would this method work?

Sure it would work. You'd just have to watch out for the undercuts. Too many undercuts and you'd have to make a multi-piece mold or else your plug would be encased in fiberglass forever.

That's how the make boat hulls & custom car body panels... It's only good for flat or slow curving planes, & requires several coats of mold release, usualy wax. Armor simply has to many curves & shaping to do with a hard mold.
The main rule is this- A soft mold for a hard casting, A hard mold for a soft casting. The only real exception to the rule is casting soft urethane ( the stuff used for batman suits) in silicone molds.
