Easy 1:1 measuring ratio. And a very durable final product. Casts so detailed i sanded the Master Form and all the cast pieces were ready for paint immediately.

This product was so easy to use, this coming from someone who has never used similar products before. I had no issues at all. Bubbles if any, were small and few but did not affect the mold. I took away one star because clean up was horrendous. I followed instructions of using warm water and soap and that created a huge sticky oily mess much like Vaseline that i just couldn't get rid of. I had to use acetone to undo what warm water and soap did. I later found out, just wiping the stuff off with toilet/kitchen roll (tougher paper) paper worked. I finished off with just running my tools under water and wiping it dry.

I had problems with this. I made a small trinket bowl and it ended up with bubbles on the rim. Tried to make a few pieces and followed instructions. The silicone rubber did not cure. Not happy at all. Very expensive product and a waste of money. Will not be buying this again.

This produces a nice flexible silicone that has a long working time. Be careful that you use plasticine that is compatible with this rubber. The Prima plastilina I used didn't quite qork and it inhibited the cure slightly.

I do like their resin, molds not happy with
