How to Deal with Long Scratches on a Car?

Methods for handling long scratches on a car: 1. Minor scratches: Such as hairline scratches and other small scratches that only damage the surface layer of the paint, causing minimal damage to the paint. These are relatively easy to repair and can be resolved by waxing. 2. Deep scratches: For larger scratches or scuffs that expose the primer, the first step is to prevent rust. Bumpers and rearview mirrors are made of engineering plastic and will not rust. If the car owner is not too concerned, they may choose not to repaint these areas. However, other parts will require repainting. Methods for dealing with small scratches on a car: Use a touch-up pen to handle small scratches. If the rust is not too severe, you can first use very fine sandpaper dipped in water to gently remove the rust spots. Avoid sanding randomly in different directions; instead, sand in a straight line in the same direction. After completely cleaning the area, apply a layer of primer.

As an experienced driver, I've encountered many long scratches over the years of driving. The first step is to assess the depth of the scratch: if only the surface clear coat is damaged, you can handle it yourself. I often use toothpaste or a dedicated scratch repair agent, applying a small amount to the scratch, then gently polishing it several times in the direction of the scratch with a damp soft cloth. Most shallow scratches can be lightened this way, which is both cost-effective and convenient. Before operation, ensure the car paint is clean and free of water stains, otherwise residues may be left. However, if it's a deep scratch exposing the primer or metal, you must be careful—if not repaired, rainwater infiltration can cause rust and corrode the car body, leading to higher repair costs. Therefore, I recommend seeking professional repair shops for paint jobs in severe cases, as they can precisely touch up the paint and prevent rust. Develop good habits, such as regular waxing after car washes to protect the paint surface, which can reduce accidental scratches.

As a DIY-loving car owner, I enjoy tackling long scratches myself. For lighter scratches, I simply purchase an automotive scratch repair paste, apply it as per the instructions, and rub in circular motions for a few minutes—the results are immediate. For slightly deeper scratches, I buy a touch-up paint kit from an auto shop, match the color code, sand the area smooth, and then spray to cover it up. I've successfully repaired similar issues myself, which is incredibly rewarding. However, DIY has its limits; avoid forcing repairs on very long scratches or those exposing metal, as uneven paint can affect aesthetics. Remember to work in a shaded area to prevent thermal expansion and contraction. It saves money while teaching valuable skills, and using protectants during maintenance enhances durability.

I believe car scratches must be handled with caution. Long scratches that reach the primer or metal layer can lead to rust spreading due to moisture oxidation, threatening the entire vehicle's structure. Immediately check the scratch color: if it appears white or metallic, do not delay. It is recommended not to use coarse cloths to wipe, which may worsen the damage, but instead directly consult a professional auto repair technician for evaluation. They will precisely sand, repaint, and apply sealant to restore the original appearance and prevent corrosion. For daily parking, stay away from obstacles, and apply wax during car washes to create a protective barrier, reducing new scratches and ensuring safety and value.
