Method for repairing car scratches with a touch-up pen: 1. First, use 1000-grit sandpaper to completely remove rust, dirt, and grease from the paint surface. Use very fine wet sandpaper dipped in water to gently sand away rust spots, ensuring thorough cleaning to prevent rust from spreading; 2. Fill the scratch with putty in multiple layers; 3. Use masking film to cover other areas to avoid overspray; 4. Open the touch-up pen, shake it well, and connect it to the spray can; 5. After securing the touch-up pen, begin spraying the first layer; 6. After ten minutes, spray the second layer; 7. Wait another ten minutes for the previous layer to dry, then apply the third layer; 8. Once the repair is complete, if the temperature is below 20°C, you can use a hairdryer to speed up the drying time between each layer.

I remember last time there was a small scratch on the car door, and I fixed it with a touch-up pen. The whole process needs to be done step by step: First, thoroughly clean the scratched area with water and a soft cloth to ensure there's no dust or stains; if there's grease, add a bit of neutral detergent to scrub. Second, if the scratch is a bit deep, use ultra-fine sandpaper (like 2000 grit) to lightly sand it smooth, remembering not to press too hard to avoid damaging the primer. Third, shake the touch-up pen well, drop a bit on an old cardboard to test the color match—this step is super important, don't skip it! Only apply it after confirming the color matches, just a thin layer is enough, don't pile it too thick or it will bubble. Fourth, wait 15 minutes for it to dry before applying the second layer; if the color difference is significant, apply one more layer. Finally, use a polishing compound to gently buff the surface smooth. The whole process requires patience and attention to detail, but the result is almost invisible and saves money, making it perfect for minor daily scratches.

The key to touch-up pen repair lies in thorough preparation and precise color matching. Before each repair, I always note down the VIN to check the factory color code, ensuring I get the right pen. Cleaning the scratch is crucial—wipe it with a damp cloth and let it air-dry for half an hour; otherwise, the paint won't adhere well. Hold the pen steady when applying, lightly tracing along the scratch direction without smudging. Prioritize thin layers, letting each dry completely before adding another to avoid buildup. After repair, check for color discrepancies—if uneven, buff lightly with micro wax. Avoid using the car until the paint fully cures. These small techniques ensure long-lasting results far superior to haphazard application.

For minor scratches, a touch-up pen is super convenient: just clean the scratch and apply the pen directly. Ensure the surface is clean and dry, shake the pen well to mix the paint. Apply by gently dabbing along the scratch a few times, keeping the layer thin without over-covering. Check the coverage after drying, and apply another layer if needed. Simple and time-saving, small issues can be fixed in half an hour.

I used to overlook the impact of weather, but later figured out some tricks: in summer when it's hot, the paint dries quickly, so I apply thin layers quickly; in winter when it's cold, avoid touching it after application and wait longer. Cleaning scratches is fundamental—wipe with a damp cloth, let it dry, then proceed. Before painting, test the color in a hidden spot to avoid mistakes; after painting, let it sit for an hour to cure, then lightly sand with a soft cloth to blend into the car body. In my experience, this method is highly effective for dealing with everyday minor damages.

Fixing scratches requires more than just a pen; you'll need some tools: prepare a wet cloth and cleaner to clean the surface, and use sandpaper for deep scratches. Before painting, ensure the scratch is smooth and dust-free; apply the paint steadily, starting from the finer areas, and wait for each layer to dry completely before adding the next. After completion, don’t rush to wash the car—wait a few days and use wax polish to blend it in. Be careful not to apply too thickly, as buildup can look unsightly. These details ensure a more natural finish.
