I need help, I got a B.A.R.C. Trooper helmet only to find out it's thin fiberglass. I paid $XX.XX for it, I got it from SF,and it looks good from the outside, so I'll keep it and try to build it up from the inside.
My question is what is the best way to do this, everything I have looked at looks like it will deform the helmet when I try. I'll post photos soon.
