Used to make my own molds and 1 year later and molds are still 100%.... Getting some more soon and its easy to use

great product! This stuff sets up fast, so make sure you are prepared ahead of time so you aren't rushing. If you want more open time use the slow 15 or 30 options offered as those will give you more than enough time to work out the process. The demoed time is super fast so thats the biggest benefit I get out of it but the silicone is super strong and tear resistant for longer lasting molds.

Moldstar fast and moldstar slow are my standard silicones for casting leaves and flowers. Light aqua is the slow version and blue is the fast. The fast works well if I'm in a hurry or know the material will whither before I can complete the process. My concern however is what happened when I ordered this product through Amazon Prime, via River Colony Trading. The product I received is not moldstar fast, but Onyx fast, A plastic resin. Lesson learned, ordering this product through Amazon is a bit of a trial and error. I would have left this as feedback on the seller's page. But it appears the seller has all negative reviews erased from their profile. Included are pictures I've made with Moldstar slow as a first layer and moldstar fast for the rest. Light green is the slow and blue is the fast. Also included is what I received from Amazon, via River Colony Trading.

This stuff is good dries fast I would say. This amount is good only for small castings for big casting ull need maybe Like 3 orders i was able to get. 2 molds Both mayb 7” inches long By 4” inches tall By 2 width Expensive but good so for small casting really good I would buy this again Mix Half and half of. Each container Mix it done pour. All set

This stuff works great and is very easy to use. I've actually purchased several sets of it. And had no problem making it work. I did have an issue with the package leaking, but I think that was Amazon's idiot driver who threw it over my back gate instead of walking to my front door. You do have to be quick since this is the fast setting, so be sure you have everything ready you want to pour on. It is messy to work with so put something down under it. Comes out a bright blue color.

I had never used any silicone and never made any molds before. I chose this to experiment with because it looked simple. Turns out it was extremely easy to use. It didn't even need degassing, which was nice because I don't have a vacuum chamber. The only issue I had was that I wanted a food safe silicone. Even though the listing said it was food safe, the manufacturer says it is NOT food safe.

I make dice molds for resin out of this and wasn't sure if the softer shore value would work well. It makes great molds- and they are lasting as long and better then the 20 shore. I usually use the Mold Star 20-which also works great for molds- but the 16- easier on the hands for sure!

When pouring the mold silicone over light objects, keep them secured. I have spent probably an hour cleaning up the edges as it floated about. But the detail is perfect love this
