Is it a Substantial Crack or a Small Scratch?
In case your window has a chip that looks just like a bull's-eye, a B.B. chip or a flowered chip, then an epoxy resin could be a fairly easy quick solution to save you money, which may either be done by a repair technician or by yourself, at home, with a window repair kit.
Whenever you can run your fingernail across the crack and it doesn't get snagged, and if the chip is around 1-inch, then a lower viscosity window resin can be employed in the repair process, which means if you're comfortable restoring your windshield yourself, an at home repair kit will be all you need.
When you've got spider web cracks or any surface area damage bigger than an inch, you'll presumably need to replace your entire window to prevent the glass from splintering more. If you're uncertain of your auto glass repair needs, call Chevrolet Cadillac of Bend at 541-693-5105 and schedule an appointment to have our certified GM mechanics take a look.
