No problem. I’ve used it personally and can attest to that it works as advertised, it is awesome. Added thumb grips to a glass lid for a cooking pot - it’s still there after 6 month of use including dish washing machine. It’s pretty much like working with clay, as mentioned it sticks to almost anything and is soft(ish) when cured.
There’s also a way to make your own with silicone sealant and corn starch. I’ve tried that too but failed miserably, couldn’t get the right consistency. (Lots of others have had success. I think I used the wrong sealant, just grabbed what I had at home)
