Phenomenal stuff! Used to make a mold with Smooth on rebound 40. My first two coats without thi-vex leaked all over the table, last coat put just 3-4 drops in and stirred for a couple minutes and thickened it perfectly, last coat stayed put and didn’t waste material…excellently stuff!!!

WARNING: DOES NOT THICKEN Polycraft GP-3481F RTV Silicone. I added lots of drops to no avail. So I ended up having to do loads of silicone layers to compensate. I know it works with ither silicones, smooth-on silicones for example, because I've watched countless videos of it working (my reason for using it). Very disappointed, but now I know. Thought I might need a pipette, but product has handy dropper already. Easy to control quantity dripped with care. Easy to remove lid.
