Hi there! First of all, congratulations for your awesome build! I bumped with your post while searching for others, and couldn't stop reading and enjoying!
Please, let me ask a question. I've made a Mk VI EVA foam, PVA coated. Now, I'd like to try something different. I'm building in this moment 2 cardboard, fiberglassed helmets, and loved cardboard! Now, I'm thinking in using cardboard in another armor.
The question is: how you strenghten the inside? I got the idea, in your first posts, that you glassed the bucket, but how about the chest and back, for example? Sorry, I couldn't understand if you glassed them or not. Additionally, what you think about rondoing the inside, withouy fiberglass?
Thanks and best regards. Awesome build!
