pepakura casting issue

[starfox64]

i started messing with it and got everything folded and glued
now im trying to figure out how i want to shape it
i found a type of foam used to shape car interiors that can be sanded to shape and casted over
i was wondering if anyone has tried this method or if im a pioneer

i'd be interested in hearing more about this.

never heard of that before, seems hard or are your just carving the helm out of foam like NAS did with the GOW armor and you would use the Perpakura as a reference
