That is pretty much the technique as I know it. I use CA to attach the bezels. Then I add Micro Kristal Klear to the inside to simulate the clear glass. Use a toothpick or small brush to apply it and fill the inside of the bezel with a generous but even coat. It is milk colored like PVA, or white glue until it dries, then it is perfectly clear, as the name implies. When done correctly, it really adds a lot to the look of the IP.
