Review: What a SURPRISE - This dries slow as expected being zero shrink silicone. It dries in about 8 hours. I have other putty that dries in 30 minutes, but the end product gets pretty hard and not really flexible. Let's Resin may be slower but it gives far better results. Flexible, strong, and most importantly, it doesn't get sticky after sitting for a month or two after molding. I have found it easy to use and clean up. I think this product is a beter value than most for the money as I tend to need les to get the same results.
Review: Cool new hobby! - It's great stuff! If used wisely you can make quite a few molds for small items. One pound is plenty enough for jewelrymakers and most hobbyists. It's easy to mix, easy to shape, and easy to mash onto items to mold them. It's a very forgiving material that allows mold-making to be a casual hobby. It doesn't stick to skin very much, and it's easy to scrape and clean up even with bare hands. After mixing the putty, you get about 3 minutes of normal working time and then maybe 5-8 minutes to fix mistakes. You can also use a nonstick material like burnished wood to flatten areas and fix edges when necessary. Today is my first day using it and I've made 5 molds throughout the day. I found that an exacto or scalpel knife blade is outstanding for trimming the excess material from these molds. Use your thumb to push/roll the excess away from the mold cavity, then slice it off. This thin, folded rubber won't resist your blade at all so you can make amazingly precise cuts. In my photo I showed how many grams it took to make each mold. (I found that a good rule of thumb is to make the backing have 2-3x as much mass as the initial layer. Use pinches to blend the layers into one solid mass.) Since taking the photo, I've filled every mold with more of the silvery epoxy. Can't wait to see the results! The first two molds, I poured epoxy into them within 20 minutes of demolding the original items. Through time, I will research this material more and try to answer the following: 1. How much heat can it take? 2. How does it work with mold release spray? Overall, it's super fun and well worth trying! UPDATE: A few days later, I have an answer for the 2nd question. Mold release spray hardly seems to make any difference. But I also have some advice. You should wash and dry these molds before using them for the first time. If you don't, the oils from the silicone putty might get into your epoxy. This is especially noticeable for small or thin items. The epoxy items cast in these molds were flexible like a gummy. After a few days they did fully harden, but it was a bit nerve-wracking to wiggle them out of the mold without bending or breaking them. I imagine this leftover silicone oil is also why people have problems with UV Resin. So, wash the molds!

### ⭐⭐⭐⭐⭐ This silicone putty was so easy to use.
*by K***D on January 15, 2026*

It worked just as described and was very easy to use. The putty dried pretty quick and was very easy to remove. The mold held together nicely. The container size gives you plenty to work with and you should get multiple uses out of it unless you are making a large mold.
