This product sounded like a great idea. I tried unsuccessfully to use it. First of all, it was almost impossible to get any of it to come out of the tube. Then, when I managed to get it out, it was difficult to shape it in any way. And it never really dried. Two days later, it was about the same consistency as when I first put it on. This product is not a solution to the problem of ill-fitting rings. However, Amazon did refund the purchase price when I told them that the product does not work.
