Review: This stuff is like trying to mix slightly softened taffy. It's SO THICK!! It literally hurt my upper arms to mix for 3 mins. And you better be fast to pot this stuff cause it cured fast. If you dont have a vaccum chamber, you must have a pressure pot. You have to have one or the other to get rid of the bubbles. Both would be ideal because the pressure pot still didn't get rid of them all. Thankfully they weren't so bad they affected my dice.... looks like most of the bubbles were what got stuck on the surface. So do not buy thinking the fridge method will work. You cannot let this sit and hope it will degas on its own. Other than that, its SUPER clear, and sturdy. I will get many dice out of the molds. Recommendation: Mix, then immediately put in a vaccum chamber for 5 mins. Then immediately pour, then right into a pressure pot. Even pouring it, its so thick, makes more bubbles. But waaaaay less then pressure pot alone. And I had it up to 40 psi. Will buy again...when I have a vaccum chamber.
Review: The silicon is great quality, you definitely get what you pay for but it is incredibly thick and because of both parts being the same color, its very hard to tell when fully mixed so you end up stirring this thing a ridiculous amount of time and switching hands every ten seconds as your wrist gets sore. However the end result is great, but if you don't need it to be clearish i would go with one of their cheaper opaque silicons since those also tend to be easier to mix. Because of the thickness it is also pretty impossible to pour in a thin strand but i was able to put mine in a pressure pot to relieve almost all the bubbles, the only ones i got settled where it was exposed to air while curing and not near the actual piece it was curing around. I saw someone say the pressure pot method wouldn't work but i tried it anyway and got excellent results. Maybe I just got lucky though so take it with a grain of salt

Pro tip: check the lot number first four digits. Month and year manufactured. The product I got was less than 2 months old (that's a good thing). Only thing I wish I had was a vacuumed chamber. This is rather viscus stuff so be ready. Ensure what you are casting/casting in is not going to react with the silicone. Once all those boxes are checked you should have zero issues. Smooth on products are awesome to work with and they have an amazing QC team if you end up with issues.
