A rock hit the windshield and caused a very small chip the size of the head of a nail (or less). At what size does a chip need repairing? I scheduled a repair from a national windshield repair chain for tomorrow, but I'm having seconds thoughts because the minimum charge is over $120 after taxes and the repair job might look worse than leaving it as it is. My insurance company no longer offers the waived deductible for windshield repair. It's a very small chip, so the only reason to repair it would be to stop it from growing (if it even has the potential to grow).
