Will there be any impact if the car paint is not repaired?

It depends on how deep the scratch is. If the scratched paint reveals multiple layers, meaning the metal part is exposed, then you should go to a 4S shop for repainting as soon as possible to prevent the metal from rusting. If only the primer layer is visible, it's not a big deal—it's just a cosmetic issue. The primer layer also serves to protect the metal. Extended information: Car painting: Car painting refers to applying a layer of paint to the car's surface to protect it. Car painting typically uses baked paint. In automobile manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. Car painting process: applying putty, sanding, painting, etc. Composition: The composition of car paint. Car paint generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives.
My neighbor recently ignored the peeling paint on his white sedan, and it turned into a nightmare. The exposed metal where the paint chipped off let rainwater seep in, and within three months, rust started spreading. The rust spread like an infection, growing from the size of a fingernail to the size of a palm, rough to the touch. The peeling paint near the chassis was even worse—hidden from view until rust had eaten through, leaving flakes of metal that could be picked off. The mechanic said such severe rust requires cutting out and replacing the steel panels, costing seven or eight times more than a simple paint repair. The biggest loss? When trying to sell the car now, buyers spot the rusted frame and immediately slash the price by 5,000—total regret. So don’t delay—fix minor damage early.
Last year, a piece of paint on my car's bumper was scraped off, and I didn't bother to fix it since it didn't affect driving. However, during a recent car wash, I discovered that the area was covered in rust spots. The car wash attendant warned that if left untreated, the entire bumper would need replacement. The exposed metal, lacking paint protection, was directly corroded by road salt, acid rain, and especially winter de-icing agents. Deep rust can compromise the structural integrity of the car body—I've seen an old car in our area whose door frame rusted through, causing the door to warp and fail to close properly. Moreover, rust can spread like ink bleeding on paper, contaminating surrounding paint and expanding the damage. A visit to the paint shop revealed that repairing the rust now would cost three times more than a simple touch-up would have. If only I'd spent 200 yuan to fix the scratch back then!
Car paint damage must be addressed promptly – I learned this the hard way. Last year, a pebble chipped off a sesame-sized spot of paint on my car door, and within two months, it developed a rust blister. When metal is exposed to humid air, it oxidizes rapidly. Once rust forms, it not only looks unsightly but also compromises the structural integrity of the steel panel. Paint damage on the chassis or suspension components is even more dangerous, as these areas frequently come into contact with water, accelerating rust formation. A repair shop once showed me a rust-eaten car frame that had become as thin as paper. Nowadays, a touch-up pen costs just over ten yuan – a simple dab can seal off the exposed metal from air and prevent rust. If you wait until rust appears, the rust removal process alone will cost an extra 500 yuan, not to mention concerns about color mismatch after repair.
