I have no idea how to describe it...it goes around the full perimeter of the glass...looks like someone used a 2" blade of some sort when they were putting in the new glass. It feels like it's something that should come off...I tried a little rubbing alcohol, nothing.
They did a crappy job on the inside of the glass...the black glue is wavy and not even Just another reason that I'll be pulling it and putting a new base gasket at some point.
Hope you can see it in the pics.
