Honestly, it helps the sealant stick better.
Finished setting up a storefront window. Walked away for five minutes. Heard a crash like a car backfired. The whole pane was in tiny cubes on the floor. No one was even in the building. What causes that?
I mean, lasers are fine, but after twenty years, my mark is just as good. Maybe it's just me, but I feel more in tune with the glass this way.
I was installing a decorative glass panel in a cafe, and this little girl pointed at it with a big smile. Her mom told me she wants to be a glazier now, which totally made my day. Do you ever get surprised by who notices your work?
