+x UpsettiSpaghetti - 4/21/2019 6:28:36 PMHey, Im sculpting this half mask and then making a brush up silicone mould with fiberglass jacket and then using fast cast for casting. Im not sure if its better to mould it as one piece or should I divide it into three sections. Also what silicone is best for brush up mould? Thank you for any help/advices.
