Mask latex or foam latex or foam
This is my first run at this type of thing. I usually only do the animatronics at the place I work and we just buy the rest. I've carved out my clay, a giant snake head, and I will be putting plaster of paris on it tonight. Next I need to understand the next step. I've been watching the tutorials, 3 each month, but it seems the instructors (who are awesome by the way) assume you already know what each of these are. If this works out, I will also want to make masks and other characters. I'm not understanding the media to use. How do I now whether to use foam latex or an RD-407 latex or should I use one of these for the outer part and just use pour foam to give it strength and a place for me to attach the mech to.
Thanks for the help.
