It depends on the situation. For minor scratches, polishing may suffice, but deeper scratches will require repainting. You can use your finger to feel for noticeable grooves. If the primer is damaged, you'll need to apply putty and repaint. Below are detailed explanations: 1. If minor car scratches haven't damaged the primer, they can be resolved through polishing. Polishing is a method of car paint care used to remove oxidized paint and various contaminants from the car body, eliminate fine scratches, and address minor paint damage and stains. 2. Minor scratches from daily driving can often be handled yourself—some marks disappear after polishing, avoiding the need for extensive repainting. However, deep scratches exposing metal require immediate attention. Even small exposed areas can lead to rust on the steel panel, making rust prevention difficult even after repainting. Car wax won't help with large scratches; if repainting isn't possible immediately, cover the scratch with toothpaste to prevent rust. 3. If you have a touch-up paint pen, use it to repair the scratch by evenly applying it around the area. Once the paint dries, reapply car wax to easily remove any residue. Car paint coating involves applying a protective film over the paint to maintain its gloss and provide a physical protective layer.

Last time my car got a few scratches from tree branches on the front, so I drove straight to the repair shop and had the mechanic take a look. He said these shallow surface scratches can be polished out—basically using a machine with abrasive compound to buff away the top layer of paint, restoring it to near invisibility. But if the scratch is deep enough to expose the primer, polishing will only make it thinner and more noticeable. He suggested testing the depth by running a fingernail over it—if you can't feel a groove, it's safe to polish. He also reminded me that polishing can only be done two or three times max, or the factory paint will wear away. If you want to avoid repair costs, a scratch remover wax bought online for a few bucks can be a quick DIY fix. Just keep in mind that polishing may make color differences more obvious on light-colored cars, while it's less noticeable on darker ones.

I have plenty of experience with car scratches—my narrow garage often causes me to scrape against the walls. Superficial scratches can be completely fixed with polishing; it's similar to buffing out scratches on a screen protector. Just remember to wash the car first to remove dust, as polishing with particles still on the surface can create new scratches. The process involves spraying on a repair agent and using a rotary polisher to buff in even, circular motions. Applying too much pressure can damage the paint. For deep scratches, don’t bother trying to polish them out—any claims that they can be fixed that way are misleading. It’s better to just repaint properly. If the scratch is on metallic paint, polishing tends to work better, while solid colors may reveal the white primer underneath. Finally, I recommend applying a ceramic coating after polishing—it provides about six months of protection.

Just helped a neighbor deal with door scratches last week. Scratches vary in severity: those only affecting the clear coat can be restored to shine with polishing; don’t hold your breath if the base coat is damaged—unless you’re okay with color mismatch. Professional shops use a three-stage polishing process, combining coarse, medium, and fine polishing pads with compound. If DIY, opt for a DA polisher over rotary to avoid burning the paint. Post-treatment, sun protection is crucial as freshly polished paint is highly vulnerable. For older cars, don’t overdo it—thinner paint is more prone to re-scratching. Remember, plastic bumpers (front/rear) are more polish-friendly, while metal door panels require caution.

Whether car paint scratches can be polished depends on the specific situation. The most direct method is to shine a flashlight at an angle - any breaks in the reflected light indicate real scratches. Polishing shallow scratches is standard practice, working on the same principle as nail buffing. However, each polishing removes about 5 microns of paint, and factory paint is only about 100 microns thick total. I recommend polishing for cars under five years old, as older cars with severely oxidized paint will become increasingly dull with polishing. Scratches on curved surfaces polish best, while edges are prone to over-polishing. It's best to apply wax after treatment, as the oil film in the polish can protect for several months. A repair shop charging 200-300 RMB is reasonable, but deep scratches may require complete repainting of the panel.

As a car owner who has dealt with three scratches, polishing has its pros and cons. The advantage is that it preserves the original factory coating without needing a paint job, and after repair, you can't feel any unevenness—small scratches can be fixed in half an hour. The downside is that it's ineffective for deep damage, and excessive polishing can make the paint's swirl marks more noticeable. My experience tells me: check the scratch under sunlight on a clear day; if you see a white line, it means it's too deep. Plastic parts are more suitable for polishing than metal areas, and you don't have to worry about rust even if the mirror housing gets damaged. A reminder: only consider polishing for scratches that touch-up pens can't handle, and avoid automatic car washes for a month after polishing—the hard brushes can ruin the newly polished surface.
