been working fine, however in order to get the wax to a very runny state,
we must heat it up considerably, which causes the wax to loose some of its

John,
I may be able to help you with the fine detail, although I don't have a
material that is water thin. I have developed a proprietary polyurethane foam
material that has excellent surface detail, low weight, very good structural
strength, and can be burned out of investment cast shells. The material and
process, called AccuCast(TM), has been used to successfully make patterns in
aluminum and silicone rubber molds.
Please contact me directly, via email or telephone, to discuss details of your
requirements.
