So originally for my Films I was going to make a mold and slush cast my helmets. My budget is getting tighter and I no longer can buy the casting material. So I would like to ask if anyone knows methods used to makes helmets out of pep to a finished good copy. I don't mind building the model over and over again because it is really easy and fast. I saw someone use a paste like material and sanded it down but I would like to here others methods. Thanks!
