How to Repair Scratched Car Paint?
3 Answers
Scratched car paint can be repaired using fine polishing wax, which works by rearranging the molecular structure of the surface paint to fill in the scratch with surrounding paint. Here is some relevant information about car paint scratches: Function of car paint film: Car paint should have good mechanical properties, fullness, and high gloss. It should also possess strong adhesion, high hardness, and scratch resistance. Additionally, it must have excellent weather resistance, scratch and wear resistance, gloss durability, and resistance to gasoline, alcohol, acids, alkalis, salt spray, and other chemicals. Precautions: Avoid repainting unless absolutely necessary. This is because the original factory paint includes an electrophoretic layer, which is absent in repainted areas. The lack of an electrophoretic layer can lead to poor adhesion, noticeable color differences, and other issues. Moreover, the original factory paint has more advanced application techniques and is of much higher quality than repainted areas.
If the car paint gets scratched, I can try to repair some shallow scratches myself. First, clean the scratched area thoroughly to avoid dust interference. Go to an auto parts store and buy a touch-up pen that matches your car's paint color, then apply it evenly over the scratch. Wait for it to dry completely, then gently polish it smooth with polishing wax to restore the surface. The entire process is inexpensive, costing just a few dozen yuan, and is suitable for small-scale scratches. If the scratch is too deep and exposes the metal, DIY repair might make it worse and lead to rust, so don’t force it. When parking, keep a safe distance from branches and stones to minimize the chance of scratches.
Repairing car paint scratches is something I frequently encounter in repair work. For shallow scratches, you can handle it yourself, such as using a scratch repair kit: clean the area, apply primer, then polish, and it can basically be restored. However, deep scratches that reach the underlying layers require professional treatment in a spray booth. Technicians will sand the area smooth, apply filler, spray paint, and bake it dry to ensure color and gloss consistency. The entire process starts at around one to two hundred yuan, depending on the area. If left untreated, rainwater can seep in and cause rust, expanding the damage. It's recommended to develop a habit of regular car washing and use high-quality car wax for protection to reduce the risk of scratches.
