There are two kinds of automobile glass, one is laminated glass and the other is tempered glass. When laminated glass is laminated, there is a layer of PVB film between the two layers of glass, which will not be completely broken when damaged or broken. Even if there is a particularly serious impact, the glass will not fall off and remain relatively intact. No debris splashing, no harm to personal safety. Therefore, laminated glass is mainly used for the front windshield of automobiles. A small impact will only crack in a small area and the glass can be repaired. Tempered glass will quickly spread into countless small particles after being damaged, which is very easy to break into whole pieces, which is more convenient for passengers in the car to escape urgently. Therefore, tempered glass is widely used in doors and rear windshields.
There are slight scratches on the black glass frame combined with the front and rear windows of the car, which may be scratched or burned by the film pasting technician when pasting the film. This kind of repair can only be replaced, and the frame is plastic and cannot be repaired. If the glass is slightly scratched, you can buy a bottle of repair liquid from Taobao and repair it yourself according to the process. The glass is badly scratched. Look around for shops that repair automobile glass and ask them to polish or repair it.
