I got it tinted the other day and this guy totally does not know how to tint the rear window. Everything looks good except the top part of the rear window. Seems like the tint is not sticking. Is this a problem that can be fixed by another tinter?

 

That sounds like bad work to me. Take it back. Duh.

 

Many coupes have the dot matrix at the top of the rear window, where the tint will not fully stick to. Some people have that part of the tint removed, and some do other little tricks to that area.
