Pits/holes in glass around edges

I use lbt100 spray for the co2, when I tried it with my ss laser, it didn’t work out too well… My communications with them was it was made for co2, not ss led type lasers…
I think both Cermark and LBT100 are about the same type/kind of spray.
Can you scrape it off? That would indicate it isn’t bonding to the material properly… Have you used it before with good results?
