Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked in a shaded area to avoid direct sunlight.
Clean the windshield surface around the crack with glass cleaner.

2. Assess Repairability

If the crack is smaller than six inches and not located in the driver's line of sight, proceed with repair.
If larger or in the line of sight, consider full windshield replacement instead.

3. Repair the Crack

Tools Required: Windshield repair kit, razor blade, suction cups, soft cloth.
If using a repair kit:
1. Follow the manufacturer's instructions included with the kit.
2. Position the suction cups around the crack as directed.
3. Inject the resin into the crack using the applicator tool provided in the kit.
4. Allow the resin to cure as specified (usually under UV light or sunlight).
5. Once cured, use a razor blade to remove excess resin and smooth the surface.

4. Clean Up

Wipe down the repaired area with a soft cloth to remove any debris.
Dispose of any materials used properly.
