Hi Boba,
Can't give you a brand name but what it is, is a Urethane foam. The ridgit stuff your probably familar with for shaping stuff to make molds from. It also comes in a flexable form and all varying densities in between. The stuff I have in mind forms a skin on the surface. When I watched it done more than 10 years ago, it was poured into a closed mold with a small openning for excess to ooze out. I think you need to be reasonably accurate with volume when pouring though.
Talk to you local plastic molding companies and I'm sure they'll lead you in the right direction.
Here is a link to a Perth company I'll be talking to when I get to that stage.

Also, how much is carbon cloth over in your neck of the woods?
I feel I'm getting robbed here having to pay $80 metre!! I've been through 15 metres [as well as 5 metres of kevlar] so far and now looks like I still don't have enough.
