Lightly sand the scratched area with wet sandpaper to thoroughly remove dirt, ensuring complete cleanliness. After cleaning the dirt, apply the touch-up pen paint on paper to match the color with the car body. Wipe the area to be touched up clean with a cleaning pad. Unscrew the upper part of the touch-up pen cap and apply the paint evenly with the brush, applying thin layers—about 2-3 layers should suffice.

As a frequent long-distance driver, I've seen many scratches on the black plastic front bumpers, which can often be fixed with simple DIY methods. First, thoroughly clean the scratched area with warm water and a neutral detergent, then dry it and check the depth. For minor surface scratches, you can buy a specialized plastic polishing compound or repair agent from the supermarket, apply it evenly, and gently wipe it a few times—this usually covers the scratches well. I once used this method with good results and saved money. However, if the scratches are deep or involve cracks, avoid risky DIY attempts to prevent damaging the plastic structure—I tried sanding it myself last time and made it worse, ending up spending a bit at a professional repair shop for touch-up paint. When parking, be careful not to get too close to walls or corners, and regularly cleaning the front bumper can reduce wear buildup. Avoid performing repairs in high temperatures, as plastic can deform when heated—it's best to work during cooler times for a simple and safe fix.

Considering that plastic scratches may affect the overall safety of the car, I make sure to carefully inspect any minor damage first. Clean the scratched area with a damp cloth to assess the severity; superficial marks are not difficult to repair, and applying some specialized paste can alleviate them. However, deep cracks must be handled by a professional repair shop, where they use hot air or special materials for safer filling. I remind myself not to experiment with aggressive methods at home, such as heating tools, which can easily damage the plastic structure. After repair, applying an anti-UV coating protects the plastic from future aging. For prevention, be cautious to avoid parking in tight spaces that cause frequent friction. All treatments should prioritize safety, and timely action can reduce potential risks.

Through multiple DIY repairs of scratches on the front bumper's black plastic, I've summarized the specific steps: Clean surface dust and dirt to ensure dryness; For minor scratches, prioritize using plastic polish to wipe along the texture for coverage; For moderate damage, first use fine sandpaper for wet sanding to smooth the surface, then apply a repair paste to match the original color; For deep scratches, consider using a heat gun for localized heating to restore shape, but operate with caution. Patience is key throughout the process, and using clean tools prevents secondary damage. After repair, apply a specialized protective layer to enhance stain resistance. I personally conduct regular maintenance to prolong the plastic's lifespan. Avoid prolonged exposure to sunlight to prevent accelerated aging, and parking in open spaces to minimize accidental friction are key long-term maintenance tips. These methods are practical, easy to learn, and yield significant results.
