i just picked up a used 1999 acura, during the test drive the windshield was fine just dirty. I picked it up and it had the standard swirls on the paint including buffer holograms as deep enough to fit my fingernail in across my whole windshield it isnt anoying its a safety hazard. Im calling the dealership in the morning but i was wondering if anyone has any ideas of what i should say / do. You can fix swirls on paint but im pretty sure this glass is unrepairable.
