Love the new square 5 gal container with the included spicket very nice. And safer to ship too. Over the years I have had two round 5 gal 25T silicone leaking when they were delivered one where the lid had come off causing major leakage so really like the new containers.
I wish this was actually in a translucent color instead of a very opaque bright green. There is one mold I want to make that will literally require carving the original shape item back out of the silicone mold. (Meant to look more natural that way, like sticks instead of flat metal.) But I wouldn't be able to see the item inside of this silicone, so I can't use it for that purpose. However, the silicone is VERY strong, and doesn't bend, so it's going to be great for my two-part molds that really need to stand on their own later.
Good product overall. The detail recovery is exceptional.
I would like the tear strength to be a bit better, though.
Just made some great utahraptor and velociraptor claws.
I strongly recommend you vacuum degas it. But it can be used without this process it on low-detail models. Very flexible. long lasting, I've got some molds with over 40 castings and still strong.
