First time customer, Will definitely buy more.

First time customer. I have almost no idea what I am doing but it still worked out. The product came in a timely manner, was easy to mix, set up as expected, did not stick excessively to my forming mold and released final parts easily.

Cast-a-mold 25T

Excellent product, my only issue is the offered container size. I think it is offered in the quart and gallon size. Since this product has a shelf life and a quart is too small and a gallon is too much. Wish a half gallon size was offered.

Excellent detail and flexibility.

I used this to mold skulls and tusks and the most fine details were captured. I am a taxidermist and highly recommend this product.
