I'm working on a homemade cardboard helmet using wizardofflight's templates. I had no luck at all using the cardboard dome, so I used a bowl I found at the local dollar store for it. Problem is, the bowl had a decorative set of dents the entire way around it, in rings. Also, it sits a bit low in the helmet itself. To try and cover the dents, I used a low of newspaper and white glue (along with coating the outer joints) to form a better dome. My question is this:
Is there a substance that I could easily use to coat the top of the helmet so that if can be formed/sculpted into a smooth dome prior to priming and painting? Sort of like a silicone gel, or a thicker gel that hardens well. I don't really think epoxy will do the trick on this one.
Also; what type of material is recommended for the T-visor? I've seen the dark green faceshield at http://www.rjsafety.com/EH21.html recommended, but is there another fairly simple material to use? I looked at using a green/smoke binder tab, but it isn't translucent enough and blurs everything, which doesn't make me too eager to use it. By the way, on the pictures, the piece in front of the visor right now is only there to hold the front roughly together while everything sets properly, it's only taped in place.
Thanks in advance!
