Ron,
Several years ago I cast some clear parts (antique auto lenses) in a
clear product that I had gotten from MCP Systems. The pieces are still
clear and surprizingly have not yellowed over time. Give Mike Wells a
call at 800-627-0222.

Question
What is the best polyurethane material (manufacturer) for casting clear =
parts?
What are some special processes required over traditional polyurethane =
castings? (e.g. heating RTV, heating materials, etc.)
Any particular issues with silicone (tin vs. platinum cure)?
Any information is appreciated.
