Haven't tried it myself Amervo, was just passing on from experience in my industry. I will back out of this discussion gracefully at this point, but will add a note received yesterday from one of my largest commercial subtrades for what it is worth.
I have a few light scratches in mine and will give it a try next month or so and post my results..
Response: "You can use jewelers polish or cerium oxide to polish out light scratches, but it takes a while esp in tempered glass."
