Rock chips can spread at any time. Statistics show that 50% of people that get rock chip damage to their windshields end up having to replace their windshield within a year of the damage occurring. Within two years of the damage occurring, 3 out of 4 suffer the same fate.
The cost to replace your windshield can be overwhelming for newer vehicles with advanced ADAS features that utilize cameras that are mounted to the windshield. Do not let a simple repair turn into a costly replacement.
