Is Car Scratch Repair Effective?
2 Answers
Car scratch repair is relatively effective. There are several methods to repair car scratches, such as using toothpaste, nail polish, touch-up paint pens, and car paint scratch repair agents. Different methods are adopted according to the severity of the scratches, and they can be quite effective. Below is relevant information about car scratch repair: 1. For minor scratches where the damage is on the surface layer of the paint, complete repair can be achieved through waxing. Use a compound to treat the area, wiping in straight lines, and then apply wax—first coarse wax, followed by fine wax, moving in the same direction from the inside out. This method can almost completely remove fine scratches. Of course, a more cost-effective method is to use toothpaste for repair. Gently apply it to the shallow scratches and wipe with a soft cotton cloth in a counterclockwise motion. After several applications, not only will the scratches be reduced, but it will also prevent air from eroding the damaged paint. Emergency products for scratches that haven't reached the primer: fine wax and touch-up paint pens. 2. For slightly larger scratches, a touch-up paint pen can be used as an emergency solution. Touch-up paint pens are available at general automotive stores. The owner can provide their car model and official color name to purchase a touch-up pen with the correct color code. Before use, shake the paint inside the pen well. Apply the primer like nail polish, and you can add a certain amount of thinner to the pen to ensure smooth spraying. Carefully spray the area that needs repair, and after the touch-up paint dries, apply fine wax. Emergency products for scratches that have reached the primer: scratch and rust remover and spray paint. 3. For more severe scratches where the color of the underlying primer is visible, the location of the damage must be considered. Generally, parts like the bumper, rearview mirrors, and some wheel arches are made of engineering plastic and won't rust, so whether to repair them depends on the owner's preference. However, if these severe scratches appear on other parts of the car body, paint repair is necessary. Otherwise, even a small break in the paint can cause the steel to start rusting, and by then, even repainting may not prevent rust. The owner should first wash and dry the car, apply rust remover to the scratched area, wait 10-15 minutes, and then wipe off the rust remover with a tissue to prevent further rusting.

As an automotive enthusiast who has driven several cars, I can confirm that car scratch repair is indeed effective, but it depends on the situation. For superficial scratches that only affect the clear coat, using a polishing compound can effectively remove them with noticeable results – the car regains its shine. For deeper scratches that reach the paint layer, localized respraying or touch-up pens are needed, and the repaired area becomes nearly invisible unless inspected closely. I've tried DIY repairs myself, spending just a few dozen yuan on tools to get the job done, though professional equipment is required for flawless results. The key is timely repair, as rainwater corrosion can worsen the paint damage. As for how long the repair lasts, it depends on the materials and craftsmanship – quality products can maintain the repair for one to two years without noticeable changes. I've also observed that regular car washing and waxing can prevent new scratches and preserve the repair results. In summary, it's effective but not guaranteed to be 100% perfect, especially for older car models which may not be as durable as newer ones.
