I want to make a silicone cast of a hand for a project
At craft/art supply stores you could buy EasyMold or similar at DickBlick
This kit and refills are available @ Amazon.com
If you want to go to the store, then in Toronto, Curry’s has silicone for sculpture
If you must have PlatSil Gel, then it’d be best to buy it direct from the manufacturer at PolyTek
