Review: Quality product from smooth-on - Worked quite well and was super easy to use as a putty. Dries to be extremely stiff and strong. Super easy clean up. I wish I could afford to use it more often, however I can't really justify the expense. If it's exactly what you need for a project, though, it might just be the ticket. I used it for a sturdy mold shell over a silicone "glove" type mold.
Review: So glad I discovered this product! - This stuff is amazing! I usually use Apoxie Scuplt, but needed something lighter weight for my current project. This fit the bill perfectly. It takes a bit longer to set up for carving details into it than Apoxie, but once I got the hang of it, it’s pretty similar. It cures just as durable, but remarkably lightweight!

### ⭐⭐⭐⭐⭐ There is a learning curve! But fantastic.
*by T***N on October 19, 2023*

I am pretty crafty and make all kinds of props, statues, models, toys and who knows what else. I have used many different products including three kinds of epoxy clay. This one is by far my favorite it is super soft and a bit sticky which can work in your favor, and very light weight which is good for larger projects or delicate ones. I like to let it sit for a few minutes (no more then five) before working with it I feel this helps with the workability. Water is also your friend it smooths out really well. I have used this from small doll props to a massive pumpkin head for a costume and I only got the trial size it's lasted for about six projects (the one in the photo took less then half of each part). Would highly recommend!!!
