Richard,
This Alumilite appears to be similar to (maybe supplied by?) the product and process sold by Dow Corning. About fifteen years ago I tried the D-C molding materials and had very good success with them. The give clean smooth surfaces, flow well into details and if you use the correct compatible products as per the instructions, they perform as advertised.

One note :: when I was trying it, the Dow product I was using recommended a vacuum evacuation of air just prior to pouring. It increased the density and strength without compromising the flexibility. I don't see that (unless I missed it) in the Alumilite instructions or spec's.

cheers, good luck and have fun !!

EDIT :: the shelf life on the D-C raw product was very short (a year or so as I recall), so buy the smallest amounts that are economical for your purpose, and be ready to use it.
