    • Worked perfectly!
Size: Pint Unit
Nice and soft and tough. I've never used this before and it came out so well. Was like a soft mattress topper feel.

    • Amazing
Size: Pint Unit
What I liked is this product did exactly what I was hoping it would do. What I didn't like was that you have to work very fast because of how fast it sets up. It just means you have to be very organized before you mix the product. I used this product on a vintage car steering wheel horn pad that the original foam had split and separated from the horn pads structure. ... show more

    • Great for making squishies
Size: Pint Unit
Buying squishies and repainting them or buying unpainted ones and painting them yourself is cool, but making your own is even better. I use silicone baking molds, candy molds and ice molds to cast mine and have had great results. This starter package will make a LOT of squishies. It is easy and the company's web site has great videos explaining everything. BE SURE to pick up lots of paint stirring sticks at some place that sells house paint because you will need them. This is great stuff an easy to use. Just know that once you mix the two parts (A & B) together you have have 30 seconds of so to get it in the molds. This is very different from acrylic casting which has a much longer pot life. ... show more

    • Read directions
Size: Pint Unit
Needs to be done in a warmer environment and be sure you mix it plenty before you pour it in. When I did it right it worked great. The only problem I had was not doing exactly as the directions said

    • Please read!!!!!!
Size: Pint Unit
This is not for the faint of heart. It is toxic and very very unforgiving. Please watch YouTube videos and read their site for help. It’s insanely sticky, so use silicon forms where you’re pouring. Measure!!! Use a scale, it makes it so much easier. 1A:2B or .575 difference. 10 grams A = 17.3g B. This is insanely important. Very unforgiving. Yellow bottle is the hardener…. Too much yellow it’s too hard or doesn’t expand. Too much blue bottle it doesn’t stay expanded and looks weird. Mix until 35 seconds and your shoulder is on fire. When you combine the chemicals after measuring exactly, mix immediately and use a timer. Mix until your shoulder burns. Really really really mix. Minimum 35 seconds, then pour. Lastly, it doesn’t like cold. Has to be 72+ or it doesn’t fully expand. This is all listed on the website and 100% accurate. Measure - mix - warm - remove after 25 min. It’s a great product and has a lot of uses if you can do the above. ... show more

    • YAY SQUISHIES!!!!!!!!
Size: Pint Unit
So my 9 yr old is all about squishies. This product was very very easy to use. However I will warn u. Def wear gloves. And don't let it get on counters, sinks etc. very hard to remove. Also I saw in other reviews to get quick release. I didn't get that and it was very hard to get out of silicone molds. Also when we did it in a plastic container or cup it didn't stick as bad and bottom came out much smoother then silicone molds. The only thing I did have trouble with was the measuring part. Didn't understand the measurements that came with it. So it was a lot of trial and error. Also when we closed containers the B container got stuck like crazy glue stuck. So it's very fun craft to do with ur kids. Just needs better instructions on how to use. I will definitely buy again ... show more

    • Garbage, no 15x not uniform results, waste of time and money
Size: Pint Unit
I've tried multiple times now, and always end up with maybe 4x expansion, voids, a skin that has separated from the core foam. This occurs every time, regardless of mold, technique, temperature etc. I've bought this kit 6 times for 6 different projects, and it's not worked any of the times. Not getting any more of my money that's for sure. ... show more
