Can touch-up paint be leveled by polishing?

Touch-up paint cannot be polished because the applied paint lacks hardness and will simply come off during polishing. Below are detailed explanations: 1. Light scratches: For light scratches, prevention is key. It's best to protect the paint when it's still new. Apply a layer of mirror glaze to the car's surface. Mirror glaze primarily consists of high-molecular polymers and works directly on the paint surface. After cleaning the car body, use a polishing machine or manual operation to vibrate and press the mirror glaze into the paint, forming a protective net-like film that significantly enhances the paint's hardness. 2. Severe scratches: If the car's scratches have exposed the primer, localized repainting is necessary.
As someone who frequently works on car paint, let me talk about whether polishing can level touch-up paint. Touch-up paint refers to small area repairs, like spraying a bit of paint to cover scratches after a scrape. Polishing involves using a machine or manual sanding to smooth the paint surface. To be honest, it can level the paint, but it might not be 100% perfect. The key lies in the paint thickness and technique—if the touch-up paint is sprayed too thick, polishing might only remove surface roughness, while deeper unevenness would require sanding first; with good technique, light polishing can blend the new and old paint seamlessly, making it look brand new. Having repaired my car several times, I've found that polishing after touch-up works well for small scratches—it saves money and effort. But for larger damage, it's better to go to a professional shop to avoid color mismatch or over-polishing that exposes the primer. Choosing the right polishing tools is also important—manual polishing is laborious and slow, while an electric polisher is faster. Don’t forget to apply wax to protect the new paint. Overall, it’s quite effective for minor flaws, simple to do, and enhances the car’s shine.
As a young car enthusiast who loves tinkering with vehicles, I've tried touch-up painting followed by polishing to smooth out scratches, which I found quite interesting. Touch-up painting involves spraying a thin layer over minor damages, like applying a small patch to the car, while polishing is about buffing it to a smooth finish. The results can be decent, especially for light scratches, but it depends on the situation. I once used a polishing compound bought from a supermarket for a DIY job—my arms ached after grinding for so long, but the paint did end up looking much shinier. However, upon closer inspection, there were still slight uneven spots, probably because I rushed to polish before the new paint had fully dried. For beginners, I'd recommend not going too hard—just gently polish a few times to avoid stripping the primer. In terms of tools, an electric polisher is far superior to manual polishing, saving both time and effort. If you're unsure, it's best to visit a professional shop—their advanced equipment can usually achieve a perfectly smooth finish. Overall, touch-up painting and polishing are great for minor daily maintenance, making the car look much cleaner, but don't expect miracles for major issues.
