Can Car Polishing Remove Scratches?

Car polishing can remove scratches, and its functions include: 1. Smoothing and brightening the paint surface; 2. Effectively removing dirt and corrosion; 3. Restoring the cleanliness of the paint surface. The steps for car polishing are: 1. Wash the entire vehicle with a cleaning agent; 2. Sand the scratched area with water sandpaper; 3. Use a machine grinder with coarse polishing compound to rough grind the marks left by the water sandpaper; 4. After rough grinding, add polishing compound for fine polishing; 5. Use a mechanical polisher with a mirror-finish treatment agent to remove swirl marks left by the coarse polishing compound; 6. After polishing, wipe off the polishing compound, apply wax to the polished area with a cotton cloth, and use a dry cotton cloth to remove any excess wax.

As an ordinary car owner who drives frequently, I find that car polishing is quite effective for dealing with scratches, especially those superficial minor ones, like the fine lines visible on the body under sunlight. Essentially, polishing involves using a machine and abrasive compounds to gently remove a thin layer of the clear coat, gradually making those scratches disappear or fade, restoring the car's shine. However, the key lies in the depth of the scratches: if they're only on the clear coat without damaging the underlying primer, polishing works wonders. But if the scratches are too deep, like those caused by hard objects exposing the color coat or metal, polishing might be ineffective and could even thin the paint further, making it more vulnerable. I've had several polishing experiences with great results, but I've since learned to inspect the car's body for scratches after each wash—handling minor issues myself with DIY tools and leaving severe cases to professional shops for evaluation. Overall, polishing is a good solution, but overuse can accelerate paint wear and affect the vehicle's value. Regular waxing or coating can help prevent new scratches.

As a DIY enthusiast, I've done polishing at home several times to remove scratches! If you have a polisher and the right polishing compound, you can tackle those shallow scratches—like fine lines from a careless washcloth swipe or minor parking lot scuffs—by polishing, as it levels the surface a bit. But before polishing, I must remind you to check the scratch depth: light ones are okay, but deep ones might expose the primer and become more noticeable after polishing. In practice, I usually test a small area with a soft cloth first to see the results before working on the entire car. When using the polisher, choose the right speed and pressure—don’t go too hard, or you might leave swirl marks or burn the paint. I’ve also found that adding a protective layer, like a ceramic coating, after polishing can extend the results and prevent new scratches. Park in safer spots to avoid debris damage. However, for deep scratches, don’t rely solely on polishing—consider repainting for a proper fix.

From my observation, car polishing can indeed address scratches, but with limitations. Polishing is effective for surface scratches on the clear coat, restoring smoothness by mechanically removing the damaged layer. Deep scratches (such as those penetrating the primer) are ineffective and may worsen the problem. The key is to assess the scratch attributes: minor marks can be treated with polishing compounds, but professional tools are required to avoid self-inflicted damage risks. I recommend consulting a technician for evaluation, as improper use can lead to uneven paint surfaces or loss of protection. Combining other preventive measures, such as avoiding hard objects when parking, can extend the paint's lifespan.
