Review: Easy to use as it's 1-1 parts A & B. I use it to cast durable, flexible cosplay accessories and armor pieces when possible. It's as thick as you pour it, but it is more rigid than the 20. I've used both and like both. SmoothOn is by far my favorite. It's a little more than another brand I've used in the past, but the quality and ease of use is worth the extra. So, in my opinion, the value s worth the money. It's not clear, one part is a tan color and the other part is clear, but if you want color, you will have to add it. I've used UVO exclusively for this along with mica powders. However, if you want a super shiny finish, brush the mica onto the mold-trust me. This works as it should. That said, if you are using this to cast a mold piece, be sure to use mold release. I had a little left and wanted to mold a small 3D printed piece. It did not come off the piece. Also, this seems to start to cure faster than Vytaflex 20, which is great for me. If you have anything that is not flat or has a lot of curves or is a mask or hat, etc, you will have to rock and roll it until it starts to cure so that the urethane doesn't pool in all the dips and hollows. It took a long time to do the front and back of the WW armor top-and I had to do more than one pour. SmoothOn is my go-to for realistic and flexible armor pieces. The photos of the bracers are my test pieces with Vytaflex 30. And the armor top was made from Vytaflex 20. I will be recasting the armor top with 30 so that it is a little less stretchy, and so that it won't feel flimsy on the thinner pieces. I had a hard time figuring out the best urethane to use for my projects, but the company is actually pretty helpful with that. 10/10 recommend.
Review: This stuff was super fun and dead easy to use (it doesn't get much simpler than a 1:1 mixing ratio). I didn't use a mold release agent, but my mold peeled out just fine. Your mileage may vary. I would definitely buy this again.

## Questions & Answers

**Q: what is the volume per 1lb ?**
A: VytaflexÂ® 30 yields a specific volume of 27.3âcu. in./lb.. https://www.smooth-on.com/tb/files/Vytaflex_Series_TB.pdf

**Q: How many do I need to make a mold box that is 5" x 5"?**
A: Think of the mold as a three dimensional box.  You need three measurements.  Length x width x height.  5” by 5” by ??   How tall is the  box? How thick are the walls of the box?  

For my project, I needed more.  I would calculate your needs and add one extra.  You can always have extra mold, but if you do not have enough, it’s hard to add more mold later.

**Q: The product says it has a shore 30A hardness. however, the description says 20A. Which one is it?**
A: It is 30A hardness.

**Q: Is this good for making mold to cast animals in concrete? Does it require a mother mold? If so, what type is best? What size mold will this make?**
A: No this is good for CASTING pulls. you wanna use moldstar 30 to make a mold of your object...than once you pull the object from the mold you can use this to make rubber casts...if you want something more hard i would suggest Resin.

*by M***W on 15 September 2017*

A little slow slash humidity sensitive to cure, hard to tell if thoroughly mixed, if you think it's mixed mix 5x longer (clear and color resin can be hard to judge when mixed)or it could be slow and or patchy. You have the wait time...so much wait time. Sturdy however would buy again.
