When stones chip the car paint, the following methods can be used for repair: 1. Toothpaste Repair: For minor paint chips on a new car, toothpaste can be used for repair. Toothpaste has a polishing function, similar to applying a layer of wax to the car, which provides a good repair effect. However, toothpaste repair is only effective for minor damage and has little effect on deeper scratches. 2. Touch-Up Paint Pen Repair: A touch-up paint pen can be used to cover the chipped paint, making it less noticeable. However, there is still a certain gap compared to the original factory paint (color difference), and the durability cannot match the original paint. 3. Note: If the stone has chipped through to the primer, metal sheet and paint treatment are required. However, this paint job is best left to professional workers, as car painting requires professional baking techniques.

I often encounter situations where stones chip the car's paint, and handling it is quite simple. The first step is to find a safe place to park and inspect the damage. Use a clean, damp cloth to gently wipe the affected area to remove dust and small debris, preventing further scratches. Then, apply a thin layer of wax to temporarily protect the surface from rust and corrosion. I usually keep a touch-up pen in my car that matches the paint color, which works well for small chips—quick and hassle-free. For prevention, I installed a clear protective film, especially on the front bumper, costing around 300 RMB, but it significantly reduces the risk. When driving, I also maintain a safe distance from heavy vehicles or construction zones where stones are more likely to fly. Leaving paint damage untreated for too long can lead to rust spots, severely affecting the car's appearance and resale value—something I care about deeply, so I always address minor issues promptly.

As someone with car repair experience, I'd say dealing with stone chips requires assessing the severity. For minor chips, simply clean the surface and use a touch-up pen (costing around tens of RMB) that matches your car color—it dries quickly in shade. For moderate damage, lightly sand before painting to prevent bubbles or peeling. For severe cases exposing large areas of primer, professional auto shop respraying is recommended (starting around 150 RMB) for durable results. Prevention-wise, I recommend regular waxing to enhance paint flexibility and slowing down on gravel roads to reduce impact. Timely treatment is crucial—don't wait until rainwater causes metal rust, which leads to costlier repairs.

I fixed this issue myself by buying a $30 touch-up paint kit and it worked perfectly. After a stone chipped the paint, I immediately wiped the car body clean to prevent stains from embedding. Following the instructions, I applied a thin layer of paint and waited for it to dry thoroughly—the result was great, but choosing the right color is crucial to avoid noticeable scars. For small dents, a bit of wax can also be used to fill them in and prevent rust. If left unrepaired, the paint damage will worsen, look unsightly, and lead to rust, which devalues the car, so I never delay fixing it.
