Review: 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!
Review: Anything by smooth, Reynolds is an amazing product. Silicone mold, making material life, casting silicone or their platinum silicone for silicone mask making best products on the market hands-down

## Questions & Answers

**Q: Can I use Epoxy Resin in this mold?**
A: Yes. It works perfect, and picks up the slightest detail from the original piece the mold is made from.

**Q: I ran out this, if i add another batch of mix will it stick together and make one solid mold? or will it seperate?**
A: It will stick together unless you use a release agent. I accidently forgot the release agent when making my 2 half mold and had to cut my model out and start over.

**Q: Can i make a silicone foot glove with this product?**
A: This material is not designed for lifecasting. It is best used in a pour on mold application of an inanimate model. Body Double silicone is rated for skin contact.

**Q: is this a flexible mold, meaning can I  make reusable molds with it?**
A: This will be used to make on form mold that can be used to cast several duplicates of the same pieces. Very flexible and durable. The details in your subject will determine how many times you can reuse it. I used a 2 piece mold and was able to cast 40 pieces from the same mold.

### ⭐⭐⭐⭐⭐ Review
*by M***O on 18 January 2019*

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.
