No, because the surface layer of the paint protection film has a self-healing coating that can automatically repair scratches. Minor scratches that are hard to avoid during normal vehicle use can quickly disappear without leaving marks under sunlight or with the car's own temperature, so polishing is not necessary to remove scratches. Here is some relevant information: 1. Benefits of car covers: Car covers can protect against wind and sand, rain and snow, prevent exposure to the sun in summer, lower the interior temperature, and protect the paint. 2. Drawbacks of car covers: The inner side of the car cover is made of flocked material. If there is fine dust on the vehicle's surface, the cover can act like sandpaper under the wind, rubbing against the paint surface from all angles. Although it may not be noticeable at first glance, under strong light, the scratches on the paint surface can become very obvious.

I recently applied a paint protection film (PPF) to my beloved car, thinking that polishing could remove minor stains. However, after applying polishing compound, the surface became hazy, and the self-healing coating was worn off, making it impossible to repair. Later, consulting an expert, I learned that PPF is not suitable for polishing because polishing agents contain abrasive particles that can strip away the protective layer of the film, causing permanent damage. Now, I simply use warm water and neutral car wash soap or specialized cleaners, which actually work better. Remember, the PPF itself is a protective shield—minor scratches will heal automatically with heat. To keep it looking brand new, simple maintenance is enough. Don’t make the same mistake I did by overcomplicating things. Saving money and peace of mind is key. Thanks to this lesson, my PPF has lasted three years and still looks great.

As someone who's been involved in car care for a long time, I find polishing PPF (paint protection film) completely unnecessary. The self-healing properties of PPF material mean that polishing can damage the surface layer, potentially causing yellowing or cracking. For daily cleaning, just use a soft cloth with water or professional cleaner; for deep scratches, it's better to replace the film entirely. While polishing the paint makes sense, doing it to the film just creates problems. With proper maintenance, PPF can last five to six years without fading, saving money and protecting the paint—why take the risk? The simplest methods are the most reliable.

After applying the car wrap, I wanted to polish a stain but accidentally damaged the film. Don't make my mistake, because polishing can deactivate the self-healing coating and increase driving safety risks. Especially at night with insufficient light, a dull wrap can impair visibility. Now I use a mild car wash solution to maintain cleanliness, letting the wrap self-repair minor issues. Prioritize safe driving—if the film has problems, seek professional help immediately. Protecting your car means protecting yourself. Keep maintenance simple.
