## Questions & Answers

**Q: Can i use with plastic? or do i need a release agent?**
A: Urethane foams are adhesive and will stick / bond to many surfaces. We recommend Ease Release™ 2831 to release urethane foam from most surfaces.
If the release application is particularly difficult (example; releasing urethane foam from urethane rubber), we recommend an application of Universal Mold Release™ followed by an application of Ease Release™ 2831. WARNING; Do not use Universal
Mold Release by itself, or any other silicone based release agents. This will collapse the foam.  You MUST perform a small scale test to determine if the release agent you use will work properly with the plastic you are casting against.

**Q: Would this work well for filling a plaster body cast intended to make a dress form for sewing?**
A: I thinking would. It is pretty "squishy " so if that's okay with you then I think it would work well.

**Q: Hi, do you also have smooth on flex foamV or 6?**
A: I am not Amazon and I have not worked with 6 (Pillow soft) but I have a sample of it. The Smooth-On web site says they make sample kits for both products and they are both similar to 3 in that they are measured by volume. The big difference is that they expand less.

**Q: What is the Shore hardness of the resultant foam?**
A: I could not find a Shore Hardness for the Foam (and yes, I know what I was looking for) but since it is their most expansive foam I imagine the number to be quite low. I am not even Shore Hardness applies to foams.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing
*by  on Reviewed in the United States February 4, 2024*

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.

### ⭐⭐⭐⭐⭐ YAY SQUISHIES!!!!!!!!
*by  on Reviewed in the United States December 29, 2016*

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

### ⭐⭐⭐⭐⭐ Making squishys
*by  on Reviewed in the United States August 10, 2025*
