Right I'm looking to make myself a helmet from halo for use in halo. Ive been over at the 405th forums (they make replica armour) but they weren't happy talking about airsoft because they thought they would get sued. Anyway what material do you think I should use? I've been suggested Smooth Cast 65D but the thread got closed before I could learn more and they seemed to not know too much about making an airsoft ready helmet. Anyway got any suggestions? I dont have a lot of money but will still like any expensive suggestions because the money situation may change in the future
