How to Repair Car Glass Scratched by Wiper Blades?

[BrantleyLee]

There are two types of windshields: tempered glass and laminated glass. The repair method depends on the type of glass. Here is relevant information: 1. Tempered Glass: Tempered glass is prone to shattering, so it cannot be repaired and must be replaced, but laminated glass can. Additionally, not all cracks can be repaired; generally, damage with a diameter of no more than 5mm can be repaired, while cracks exceeding 20mm are not recommended for repair. 2. Laminated Glass: Small circular cracks can often be repaired by yourself. Laminated glass consists of two or more layers of glass with one or more layers of organic polymer interlayer film in between. Through special high-temperature pre-pressing (or vacuuming) and high-temperature, high-pressure processing, the glass and interlayer film are permanently bonded into a single composite glass product.
