    Great casting mold material

    Posted by Keith van brunt on Sep 19th 2020

    I have had trouble creating molds for casting small 1/8 inch stars created from dowels. This product worked great as the molds were durable and allowed me to slide the star shaped stick out of the mold after curing for +24 hours.
