Cheers,
Dave Leonard Thanks Dave.  To make the radiator ducts, I was actually thinking of doing this.  I figure I can wrap the core in plastic, tape the mouth of a kitchen garbage bad around the inlet side of the core, open a hole in the bottom of the bag, then fill it with foam.  My thought is that this will leave me with a nice ball of foam to be shaped.  Can anyone think of a better approach? Thanks,Rusty (I sure won't use expanding foam from the spray cans again)
