Scratched Glass Repair – Windshield Scratch Repair. This Alfa Romeo windshield was badly scratched from running windshield wipers without the wiper blades! There were grooves in the glass that were significant. As you can see, we did quite a bit of grinding the damaged glass down. However, we have a very neat, non messy, unique and aggressive system we developed for this very purpose. The glass was restored back to almost new but without the grooves, and scratches. If you have original classic car glass and wan’t it to look near perfect again, send it to us. We can give you details about shipping and insuring it.
