This solution worked well for me. I was able to line the inside of my oversized rings easily. I applied up to three layers using the nozzle to guide the gel over the lower area of the ring. One thing that was hard for me to understand was the instruction to keep the ring vertical for 24 hours after application of the gel. The gel is stiff enough for you to place the ring upside down resting on its top without having it run down the sides. So, I placed the ring with the stone side down on a soft cloth to protect the stone, which kept the ring in a vertical position. This let the get set and dry. I have not had any problems with the gel slipping off the ring. It works very well, and another side benefit is that the gel adheres a bit to your skin, so the ring doesn't twist around your finger either.
