Automotive glass is generally transparent. When the glass cracks, air will enter it. This contact between air and glass causes light to refract, so we can see cracks in clear glass. If not repaired in time, the air will further open the cracks during driving, causing the cracks to become larger. Therefore, once cracks are found in the glass, we recommend going to a professional auto glass repair shop to repair them as soon as possible. This prevents cracks from expanding and maintains the integrity of the glass.
Be careful when gradually filling the cracks (the cracks are complicated and it is difficult to inject glue). The details of restoration are complex and experience is key. If the glue is not fully injected, cracks will remain and the effect will be poor.
As for whether it is reliable, it depends on the size of the crack. If the crack is just a little bit but not too big, it can be repaired directly without any problem.
But there are some special situations to consider.
1. The crack is a bit big
The traces of this kind of crack repair will be a bit large, so it needs to be considered appropriately.
2.Exceptionally long cracks

Scratches on the glass can be removed by grinding, but they are limited to small and shallow scratches. It is best not to be within the driver's line of sight, because the glass is lost during grinding, and large areas may affect the line of sight, so for safety reasons It is recommended to choose direct replacement.
First of all, you need to do a simple cleaning process on the car glass to prepare for glass polishing. The specific method is to wrap the glass to be repaired with tape in advance. The purpose of this is to prevent the car from being stained during the polishing process. The next step is to clean the glass glossy paper. Pay attention to it carefully to avoid the presence and adhesion of dust. Note that before polishing, use a marker to circle the parts to be repaired on the back of the glass to avoid shifting and causing a certain impact on the glass.
Finally, you can use glass polishing paper. The order of its cutting ability is green (for deeper scratches), water red, blue (often used for light scratches), brown and white.
Use moderate pressure during specific operations, and be level with the surface of the tray and glass. If you used 35µ glass green sandpaper in the first step, you must use 10µ (blue) glass sandpaper next. After that, you can use brown and white glass sandpaper to restore the original clarity and transparency of the glass surface.
It should be noted that when starting polishing, the polishing disk must be placed flat. After turning on the machine, it should move back and forth slowly. After a few seconds, a white slurry will form. Continue polishing until it is dry and throw away the slurry. The luster that the glass should have is enough.
There are also simple ways to repair car glass scratches. You can also choose to use glass repair agent or professional crack repair tools. The effect is much better than glass repair agent, but it requires professionals to handle it.
Of course, if the scratches on the glass are deep, it is recommended to choose a more reliable and reputable beauty shop for beauty treatment.
If you replace the entire piece of glass just for a small crack, it is not only wasteful, but also really not worth it; if you ignore it, the wind pressure will make the cracks bigger and bigger, which will not only affect the appearance, but also pose a threat to safety. At this time, auto glass repair would be an ideal solution. Automobile glass is a kind of double-layer laminated glass. When it is hit by an external force, if the force is not enough to break it and only produce cracks, the middle gluing layer will separate due to air entry and atmospheric pressure. If you continue to drive, the cracks will appear. The area will become larger and larger, affecting visibility and driving safety. Auto glass repair treats glass cracks or small wounds. The operation time is short and will not affect daily use of the car.
How to repair windshield cracks:
1. Use a vacuum syringe with a needle-like structure to remove the air from the glass wound.
2. Fill the cracks with glass repair agent (liquid colloid).
3. After repeated pumping and pressing treatment several times.
4. Use ultraviolet light to illuminate up, down, left, and right for two minutes each to allow the repair fluid to solidify.
5. After the machine is removed, there will still be a small gap in the center of the wound. At this time, drop in a repair agent with a higher concentration, cover it with a glass piece, irradiate it with ultraviolet light and dry it with a blade. Smooth the surface, apply polish, and polish with a cloth.
