Does anyone know why I am getting these pits, or random holes in the image and around the edge of my image in the glass?

      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?
