This is 5.7oz carbon fiber cloth that is applied using a plastic called 16-30. No resin used here. In general, resin is an awful material to use. Resin is soft. 16-30 is dense and what we use in studio molds for helmets and costumes.
I was watching your site but you took the helmet stuff off and seemed to be focusing on MG's and trooper items. It's nice to see the helmets and the webley.
