What are the methods for dealing with car scratches?

Methods for dealing with car scratches vary depending on the situation: 1. Scuffs: Apply a coating agent matching the car body color to the scratched area, ensuring even treatment across the entire body; 2. Minor scratches: Use water-soaked sandpaper to sand in straight lines along the same direction, remove rust spots and clean, then apply primer. After the primer dries, sand it smooth with water sandpaper and use a touch-up pen for coloring; 3. Small scratches: Wipe in straight lines until the scratch disappears, then polish with a compound and apply wax; 4. Deep scratches without primer exposure: Use a fine brush tip to apply touch-up paint, then apply fine wax after the paint dries; 5. Deep scratches with primer exposure: Wash and dry the car, apply rust remover to the scratched area, wait 10 to 15 minutes, then wipe off the rust remover with tissue paper.

Oh no, my beloved car got scratched! Last time it was scraped in the parking lot, I handled it myself. For shallow scratches, first use toothpaste on a damp cloth and polish in vigorous circular motions. Remember to wash the car first, otherwise sand particles will make the scratches worse. For deep scratches that expose the primer, apply touch-up paint to prevent rust. I keep a bottle of matching paint; shake it well before applying and apply three to four thin layers. However, for large areas, it's better to go through insurance and take it to a repair shop—they have professional paint booths, and the results are much better than DIY. Remember to take photos of the license plate, full scene, and details at the accident site, and file a report within 48 hours without delay. Scratches on plastic parts can wait, but if metal parts are exposed, deal with them immediately.

The treatment for car paint scratches depends on the severity: For minor scratches that haven't reached the primer, buy a polishing compound and apply it yourself. Don't believe online remedies using essential oils as they damage the clear coat! For scratches exposing the metal layer, immediate action is required: 1. Clean and dry the scratched area; 2. Gently sand rust spots with 800-grit sandpaper and water; 3. Apply filler putty and let it dry for a day; 4. Apply three thin coats of touch-up paint with 30-minute intervals; 5. Once dry, sand smooth with 2000-grit wet sandpaper and soapy water. Finish by waxing to conceal the repair. Remember that post-repair paint has poor durability—choose a touch-up pen with UV protection for outdoor parking. Plastic parts like bumpers don't require urgent repair.

From a cost perspective: Minor scratches on the bumper can be ignored, but it's recommended to treat scratches on metal parts that expose the primer. A paint repair at a 4S shop costs about 600-2,000 yuan per panel, while regular repair shops charge 300-800 yuan. Small dents can be fixed with a suction cup repair tool purchased for just a few dozen yuan. If you don't have sufficient scratch insurance coverage, DIY solutions are more cost-effective: Light scratches can be 80% concealed with scratch wax, while exposed white marks can be covered with a touch-up paint pen kit (around 80 yuan, including sandpaper and filler). Key points: Avoid rain for 24 hours after touch-up! Don't wash the car for the first three days! Money-saving tip: For minor damage on non-critical areas like mirrors or lower door panels, consider accumulating them and repairing all at year-end.
