Well your next step is to resin and fiberglass the helmet to harden it, you should put 2 or 3 thin coats of resin on the outside the helmet, but you should put less resin on the detailed parts so the resin wont cover it up.You have 2 options for the inside of the helmet. 1. You fiberglass the inside with resin and fiberglass cloth. 2. You RONDO the inside of the helmet. I like to fiberglass mine because it makes the helmet very light when you have it resting on your head. RONDO is like resin but hardens like cement on the inside. If you choose to fiberglass it, it may take a little longer to fiberglass it than RONDO it, but it's worth it, so i believe on my preferences. Anyway this is a very nice start for your first pep. Who were planning on making the helmet based off of? Mickey? Romeo? Rookie? Or Buck? Be sure to keep me informed i wanna see your progress
