Remove the wax film layer, oil film, and other foreign substances from the surface of the paint, clean the scratched area with a wax-removing cleaner, and then let it dry. Use appropriate sanding materials to sand the scratched surface layer. Apply a polishing compound soaked with water, keep the polishing pad surface parallel to the paint surface to be polished, start the polisher, and stop the polishing process when about 95% of the scratches are removed. For any remaining fine scratches or swirl marks left from the sanding and polishing process, perform paint surface restoration. After paint surface restoration, apply wax treatment and repeatedly wipe until the paint film is smooth and shiny.
As an ordinary car owner, I often encounter minor scratches on the car body. When shallow scratches appear, I immediately take action to repair them to prevent them from worsening. The specific method is to first find a shady spot to ensure the paint surface is cool, then clean the scratched area with water and a soft cloth to remove dust and impurities. Next, apply a dedicated scratch repair agent, such as polishing paste from popular brands like Volkswagen, which works quite well. I gently massage the area in circular motions for a few minutes with a fine sponge, applying it evenly without using too much force to avoid damaging the paint. Afterwards, I apply a layer of car wax to protect the repaired area and prevent new scratches. This method is simple and easy to do, and I've used it several times myself. For example, last month there was a scratch near the door handle, and after treatment, it was barely visible, saving me the cost of professional repairs. By the way, developing this habit is beneficial for long-term paint care, especially during rainy seasons or cold weather, as timely treatment can prevent corrosion.
I prefer to handle minor scratches myself with practical steps to ensure effectiveness. First, thoroughly clean the scratched area with a slightly damp microfiber cloth. If the scratch is shallow, apply a scratch repair solution available at supermarkets and gently polish it to fix the issue. For deeper scratches, consider lightly sanding with fine-grit sandpaper dipped in water, but be careful not to over-sand and damage the paint layer. After the operation, seal it with wax; I recommend liquid wax for quick absorption without residue. I've used this method—it's cost-effective and quick, especially suitable for people like me with limited time. Avoid working under direct sunlight as high temperatures can make the paint brittle and affect the repair. Related tip: Avoid parking near branches or hard objects to prevent scratches, and regular waxing can significantly reduce the likelihood of scratches—a good habit for average car owners.
