Awesome thank you for the advice! Yeah I bought a dust mask just for the fumes of the epoxy + hardener, which helped but it didn't completely block out the smell. I'll see about getting a respirator when I get more time and money to buy more supplies. Where do you get your stuff and what method do you prefer? Any experience with making polyurethane molds? Sorry for rifling off questions but I don't know anybody that has any experience with this stuff so I'm just going off what I've read about. Like I said in the OP, my final goal is to re-make my open mouth grill of carbon fiber so if that gives you an idea of the path I'm trying to take.
