Review: Read the directions and move fast! Works great! - good product but you got to be quick in doing what you need to do with it! I mean QUICK!
Review: Amazing isn't a strong enough word for this product - Amazing isn't a strong enough word for this product. It takes detail, fine fine FINE detail very well. First introduced to this product at Gencon, I have used it in multiple builds, it has been used on stage, and exceeded expectations time and time again. I've used 325 for props but it's also been used to create items for daily use. It has a pretty solid sheer when mixed correctly, and it takes color very very well! I have yet to find a product by Smooth-On that has failed to deliver! Easy to use, can be adapted to serve multiple uses, and when I've contacted Smooth-On they have had people who are actually familiar with their product, and make intelligent suggestions from experience. Both the product and the Smooth-On seller here on desertcart are rock solid On the pictures look closely at the unfinished silver of the Corvo mask I built, the fake tool marks I made in the monster clay transferred perfectly to the final cast. In the second build progress shot, you can see where the copper wire was being bent to fit the piece. The sheer of the 325 took the abuse without issue. The final shot was part of another build, and I happened to mask off half for paint. You can see in the shot how the 325 looked before and after paint and the fine detail that was caught. I did not make a single cast in a vacuum environment, these were all straight mold casts using Oomoo 30 and Smooth Cast 325

### ⭐⭐⭐⭐⭐ kicks fast, cures hard. Satisfied with the results.
*by K***. on April 6, 2019*

This stuff kicks fast, so make sure you've got all your molds ready before you pour. Its fairly good at self degassing, but to be sure, try not to stir too vigorously when mixing so as no to introduce a lot of air to the mixture. As it sets fast, this stuff works great for including chunky glitter, gold leaf, or inclusions, avoiding a lot of unwanted sinkage that you'll get out of longer-setting resins. Worth the money, although when poured clear, cures with a slightly yellowish tint. Not ideal for crystal clear pours. I'd love to try Crystal Clear 202 some day.
