I have used it. It works! Requires sunlight to cure. I have found the cure to be somewhat unpredictable, but when you do it right it leaves a clear, hard, durable finish. I emphasize that I have only used it a few times. A little goes a LONG way. Rub it in with a paper towel and leave it in the sun. When cured, you can tell because there is no slickness. It is buffable and sealable. You can definitely see the difference in those areas where it has been applied. My only wish is that I had a little better control over the cure process.
