1. Do not polish the car windshield
2. The crack exaggerator is sucked into the car at the back of the crack. The plastic screw is placed on the crack to enlarge the tear crack and the glue quickly enters the crack. The dilator is a product many years ago. At that time, there was very little car film attached to the sun. A slight inadvertent use of the dilator will increase the length of the crack and occasionally damage the solar film on the glass inside the car.
3. If the crushing point is in the black area such as pitting or rubbering or has stretched pattern and is in the main line of sight and the crack is too large, the main body of the damage exceeds 20mm, try not to repair it, and need to replace the glass.
4. Need to dry again, in the shade, without direct sunlight.
