Window tinting - rear glass 2000 Hardtop Corvette

On the 2000 hardtop Corvette rear glass there are alot of these little
black dots at the top of the window. The tinter said that the tint
would not stick and it will look bad.

Has anyone had this problem on their hardtop and any recommendations
as to who and how it should and could be tinted?

One person suggested getting some solid black tint from the area of
the black dots and then regular tint below that.
