If the objective of this process is to get a one-shot "silicone rubber model",
then I would suggest that you create a wax mold and pore RTV silicone rubber
into it. Then after it has cured melt the wax mold away.

Greg Pettengill I do not know if it is true, but I imagine that
there are scientists
greg_p@indirect.com who, by following the paths of the so-called
"cold" intellect
(602) 375-2922 -possibly without being aware of it- are plumbing
the depths of a
                          mystery rather than searching for the solution to
a problem...
