Love this product
Use it all the time, it is perfect for molds, especially if you want to see what you're casting while you pour. Great flexibility for release and it lasts for many casts.

Advertising is wrong
Link shows use equal amounts but it's by weight not volume according to directions inside box. I had purchased for a large project and the scale wouldn't go passed a certain weight so I had to pray it's work. It is pretty expensive. I used nearly both bottles which are smaller than appears in photo to make flower pot mold and tray. I would recommend using its for smaller projects. It is very thick. I had to cut mold to remove original pot I used to copy.
