Is the Car Paint Scratch Remover Really Effective?
2 Answers
Scratch removers can only eliminate very minor and shallow scratches; deeper scratches still require polishing for a solution. In fact, the effect of car scratch repair fluid is similar to toothpaste, offering decent results for minor scratches on the car's paint surface. However, for deeper scratches, car scratch repair fluid is largely ineffective. Below is an introduction to car paint layers: 1. Electrophoresis Layer: During car manufacturing, the entire body is immersed in an electrophoresis tank. The electrophoresis layer directly adheres to the metal body, serving to prevent rust and enhance the paint's bonding capability. This layer is crucial for rust prevention. 2. Primer Layer: The primer layer acts as a bridge, providing better adhesion for the next layer of paint while protecting the electrophoresis layer and improving rust resistance. Additionally, it plays a vital role in the smoothness and impact resistance of the paint. 3. Base Coat: This is the colored layer, responsible for the vibrant hues seen on cars. Many manufacturers now use metallic paint for the base coat. 4. Clear Coat: Applied as the outermost layer, the clear coat enhances the paint's glossiness and protects the base coat.
Last time my car door got scratched by a roadside branch, I followed the trend and bought a viral scratch repair cream. Only after using it did I realize it's not about whether it's a 'magic tool' or not—the key lies in the scratch depth! For hairline-thin white marks, using an abrasive repair cream in circular motions can indeed polish them away, similar to how toothpaste works. But if you can see the black primer layer in deep scratches, applying the cream is like putting foundation on a wound—it becomes glaringly obvious under sunlight. What's worse, some low-quality products contain strong solvents; my neighbor's white car actually turned yellowish after use. Now I handle scratches in three steps: drag your fingernail sideways across it—if it catches, it's a real scratch needing touch-up paint; for rough-feeling superficial scratches, buy reputable brand abrasives for manual polishing; for anything over half a centimeter, go straight to professional respraying to avoid rust penetration costing more later.
