Yes. This location is a few inches forward of the engine water intake. It was covered with the soft black layer and had soft glass underneath so it had to be ground out.
Some of the black layer is hard Some is hard and over solid glass, some is soft over solid glass and some is soft over delaminated glass.
I'm leaning towards the theory that it was repaired more than once. That would explain the normal glass at the deepest layer and the blue glass near the surface. Still donn't know what the black layer is.
Plywood sounds unlikely but maybe if they used a plywood form to cover with glass.
