Is Glass Scratch Repair Fluid Effective?
2 Answers
It is most effective when used indoors, as only then can the best repair results be achieved. Below is more information about automotive glass: 1. Classification of automotive glass: Automotive glass mainly falls into the following three categories: laminated glass, tempered glass, and zoned tempered glass, which can withstand strong impacts. Automotive glass is categorized by its location into: front windshield, side window glass, rear windshield, and sunroof glass. 2. Manufacturing of automotive glass: Automotive glass is manufactured by heating the glass in a furnace to near its softening temperature, then rapidly transferring it to air grids with varying cooling intensities for uneven cooling. This process creates different stress levels between the main viewing area and the peripheral areas of the glass. Generally, glass produced this way is zoned tempered glass.
Last time I had a small scratch on my car window, I bought some repair fluid to try it out. The effect was okay, mainly for superficial scratches. After applying it to fill in the scratch, it became less noticeable, but deeper ones didn’t work as well. When using it, I had to make sure the glass was clean and the temperature was suitable, otherwise it was hard to handle. The downside is that the repaired area might oxidize and turn yellow over time, requiring reapplication. For daily driving, it’s best not to wait until there are multiple scratches—address minor ones early, otherwise visibility can be seriously affected during rain or at night, which is quite dangerous. Overall, it’s a cost-effective and convenient DIY solution for small issues, but for major scratches, it’s better to go to a professional shop. Also, when washing the car, use a soft cloth to avoid hard objects damaging the glass and prolong its lifespan.
