Gray Matter molding silicone rubber

Discussion in 'Fish Taxidermy' started by BigShotshells, Feb 13, 2017.

  1. Back in the 1980's I was molding fish with a product called "Gray Matter" that was sold by Peter Wilson in Connecticut. It was a superior product that would cure against a damp fish and would self-level at about 1 mm. You would then apply a thin flash coat of plaster, followed by a heavier layer, to produce the mold jacket. It wasn't a heavy duty, production type of silicone where you could crank out dozens of castings but it worked perfectly for one-of-a-kinds or small runs.

    Does anyone know if this material, or something similar, is still produced? There may be a different version out there in another color or something but I'm not finding it. Did a search of the forums but couldn't find any previous mentions.

    Thanks, Dale

    Ha! I use to use this stuff a lot casting fish heads, and I loved it! Still have molds that are in perfect shape over the years. It has a strength and texture unmatched still today! My only problem is that there isn't any more steel head to mount and use my Grey Matter molds for :-\
