I could use your help guys.
I spent about 60 hours sculpting a shock trooper helmet. I bought a really expensive silicone and it worked great. I messed up because I didn't make any locks or keys. So It wouldn't fit into the fiberglass jacket. Never the less my first attempt failed miserably and my awesome sculpt was ruined. not by the moulding process but something else happened.
My question is. What is the BEST way to make a helmet from start to finish? Is vacuum forming a good way? I want to make a really sturdy helmet and I don't care how many steps are involved. Any help would be much appreciated.
