Thanks bro. Gonna try to Urethane them Saturday if I have time. Also waiting on ink for our printer at the moment. I think I have totally decided to do a scout helmet but I may continue making the ODST helmet afterwards.
I actually have a friend who made the every part of the armor except the helmet. He used real metal on most pieces, and we just added a metalic coating that was olive green. It looked a little darker than the real halo armor. Remember have fun when doing it!
