When someone replaces your windshield, and doesn't care about your car, bad things can happen. Errant blades, improper removal methods, carelessness, all can lead to scratches on your pinchweld. These scratches, if not treated properly with industry specific primers, will eventually rust and cause premature failure of your windshield installation. Make sure your windshield is replaced by someone who cares!
When an installer scratches your vehicle, they need to take the proper steps to primer and prevent it from rusting!!
