Nah, the foam isn't going to work for this part. It's too slow, bendy, soft, messy, nasty, dumb.

Also, I just don't like it. Several attempts at making various parts with it over the last 5 years, much disappointment.

Working the rigid foam is easier, faster, more precise.

The rigid foam your using, is it like styrofoam insulation? Will you be coating it or covering it with anything?
Exactly - rigid foam insulation. (Not styrofoam... more dense. I'll get the name off it later.) I started shaping the parts last night, and it's much better to work with than the bendy, soft, messy, nasty expanding foam.

I'll be coating it with 2 part epoxy (doesn't eat foam).

I'll post up pics of my progress later, after today's session.
