What Materials Are Used for Car Glass Polishing?
2 Answers
Car glass polishing generally requires polishing liquid or polishing powder. The main component of polishing materials used for glass polishing is cerium oxide. The polishing powder used for glass polishing is usually cerium oxide polishing powder, while the polishing liquid is a water-soluble polishing agent that does not contain any sulfur, phosphorus, or chlorine additives. Both materials have moderate hardness, enabling fine polishing of glass with excellent results. Below is an introduction to car glass polishing: 1. Before polishing, it is necessary to clean the surface of the glass to remove any impurities to avoid secondary damage during polishing. Then, apply the polishing liquid to the polishing machine for polishing. It is important to ensure that the polishing force is even, the applied pressure is appropriate, and the grinding is slow and precise to guarantee the desired effect. 2. If the glass has deep and large-area scratches, polishing is not recommended for repair. Deep scratches require greater polishing force, which increases the wear on the glass at the scratch site compared to other areas. This can thin the glass, causing visual distortion. Especially during nighttime driving, incoming vehicle lights can easily form halos, interfering with visibility and affecting driving safety.
I'm a regular at auto detailing shops. For glass polishing, cerium oxide polishing paste is typically used, which works well for removing light scratches. When operating with a polisher, first clean the glass thoroughly, lightly sand deep scratches with fine sandpaper like 2000 grit, then apply the paste and polish in a rotating motion. You'll need a buffing wheel and a soft cloth for finishing—don't forget safety goggles to protect against dust. Be careful not to polish too frequently, as the glass can thin and become prone to breaking. Daily driving habits like avoiding gravel can help reduce scratches.
