I have a tail mold, now some questions

I was lucky enough to get a two piece cnc routed tail mold. Lots of curves in the outline. I've tried several things, but not having a cnc router to cut the cores, hand sanding isn't working well. While I can get close, and compress the foam with the molds during the build, it looks to me like the foam is compressing and then expanding a bit. So I'm not happy.

I thought I'd try bagging a thin piece of foam into each half of the mold, hot wiring it after it sets up and then joining them in the mold.

What foam can I hot wire, that also wont compress and expand? Is rohacell the only foam that has that wont expand? I understand if it dents that hot water wont cause it to expand.

Alternate methods would be considered, but I'd like to try this.
