Do I need to remover rear window?
I have an Alfa Romeo Giulia (2019) that I bought seconde hand from another country. On both the right (first picture) and the left (second picture) I have rust under the paint. I want to repair this rust but I'm afraid of removing the rearwindow (700 euros for a new one). I can not see any rust under the estethic seal. Is there a chance there is no rust onder the rear window or is the chance slim to none?
