Since I live in an apartment and have a toddler at home, I have to be weary of what kind of materials I use. I know that latex has ammonia and that it is obviously not good to breath and or unpleasant to smell.
I was wondering about urethane rubber. Also are there any casting plastics that I could use that won't stink up the house or require a respirator?
The project I'm working on is a batman helmet cowl in case it matters.
Any comments are greatly appreciated
