Avoid Sudden Temperature Changes
Rapid temperature changes can increase stress around an existing crack. On cold mornings, warm the vehicle gradually rather than directing maximum heat immediately onto the damaged area. In hot weather, avoid blasting an extremely hot windshield with very cold air.
Drive Smoothly When Possible
Potholes, rough railroad crossings, hard curb impacts and slamming doors can flex the vehicle body and add stress to damaged glass. You cannot eliminate road vibration, but avoiding unnecessary impacts can help while you wait for service.
Keep a Chip Clean
For a small chip, keeping dirt and moisture out can improve the conditions for a professional repair. Clear tape may be used temporarily if it does not interfere with visibility. Replace it if it becomes dirty or wet.
Do Not Put Household Adhesives Into the Crack
Superglue, nail polish and other improvised fillers can contaminate the break and may make professional repair more difficult. A windshield repair system uses specialized resin and controlled preparation, not household glue.
Park in a Moderate Environment
Shade or a garage can reduce thermal cycling when temperatures are extreme. Do not force a cracked windshield through a car wash or pressure wash before it is evaluated.
Schedule Repair Before It Becomes Replacement
A small repairable chip can become a replacement if it spreads or reaches an edge. If the damage blocks the driver’s view or the glass appears unstable, avoid driving until it can be handled safely.
