I'm intending to make a cowl loosely based off this design.
Meaning, I'm intending to do a 2 piece helmet and collar style cowl for comfort and flexibility.
I'm not sure if I want the final pieces to be made out of silicone, urethane rubber or something else. Whatever I decide on to use as the final material will impact how I go about creating the molds and what not.
Has anyone had any luck on slush casting/brushing in silicone in a mold and not using a core?
Any ideas or input?
