Sorry but here's something to prove you wrong, the mask is hard as hell, it is paper mache right, but it is very f***ing strong, to the point that it causes irratation on the skin if you strap it on too tight, I mainly paper mached it for two reasons:
-I f***ed up from the start by using disolvent glue
-To prevent warping
and now it is damn hard, I was thinking about casting it but I don't know how to cast it and what it would be like, I mean, it's a hollow mask, how am I casting that without getting stuff inside thus losing it in a block of silicone? what do I do? I don't want to resin it mainly cause I don't want to waste money on something I can do with paper mache and secondly cause it is dissolvent and I would cry to see my effort fall apart, I was also considering bondo.
