There have been a lot of posts about engraving glass lately......and Marty was kind enough to post the link to the JDS YouTube channel.....one of the videos showed a demo of "glass laser tape"........I did a search on here, but I got about 4,000 results........So, has anyone used it? If so, does it work better than the dish soap technique? Does it work like a mask in that you can paint fill the engraving?
