The crack repair of automobile windshield is only suitable for small cracks. First, prepare special crack repair tools.

1. Clean up the place where cracks need to be repaired before repairing, so as to avoid bad influence after repairing.

2. In order to see the crack clearly when repairing, an observation plate should be attached to the cracked inner glass.

3. Fix the suction cup base and align the center point with the crack.

4. Align the pressurizing device with the crack and fix it on the sucker base. After determining the position, unscrew the upper part of the pressure lever.

5. Pour the repair liquid into the top of the pressurizing device, and then screw the pressurizing rod back to the base.

6. Wait for about ten minutes for the patching solution to penetrate and solidify, and then screw out the pressure bar for one minute to exhaust the air in the crack.

7. Remove the repair device and observation plate, and scrape off the residual repair liquid with a blade.

Matters needing attention when traveling in foggy days:

1, if the fog is heavy, turn on the fog lights and low beam lights, and the high beam lights do not need to be turned on, which will make the driver's vision more blurred.

2. If you see the fog light on the front of the opposite vehicle, it means that there is heavy rain on the road ahead, or the fog is relatively heavy. At this time, if the owner prepares in advance, he should pay special attention to safety when driving.

3. Get into the habit of honking more, so as to warn the vehicles and pedestrians on the road and avoid traffic accidents.

4, don't drive along the side of the road, so it is easy to hit the car parked on the side of the road.
