Well...to be more specific. They seem to be out near the edge. I am working an 8" piece of plate glass and the scratches (or sleeks) are all in about the outside 2 inches. They do run in multiple directions so they are happening during the session.

What is the difference between a "sleek" and a scratch? The initial scratch I am sure about, it was one straight line with a corresponding line that cut through the middle where I changed direction with the the tool. It was obvious even before the surface dried. That is the one I went back to correct the first time. All of the later "scratches" I have seen and somewhat more subtle.

What I am seeing now are small scrapes. They are not visible directly or when the glass is wet. They show when the surface is dry and held at an angle to the light source. Generally I need to moisten the surface with a breath of air to intially see them.

I am describing them as scratches becasue I don't know any better (this is my first mirror).

Thanks,
Dave
