To make the area repaired with a touch-up pen smooth, follow these methods: 1. Use fine sandpaper to smooth it out; 2. Polish it with toothpaste. A touch-up pen is a tool for repairing car scratches. Simply choose the right color that matches the original car paint and apply it to small scratches or areas where the paint has peeled off to repair the damage. Precautions for using a touch-up pen include: 1. For minor scratches, only a touch-up pen is needed—no sandpaper is required; 2. Do not unscrew the cap when the pen is placed horizontally or upside down to avoid paint leakage; 3. Store it in a cool place out of reach of children; 4. Avoid contact with skin or inhalation of volatile gases.

I have a little trick to share since I often deal with minor scratches on my car. The unevenness after using a touch-up pen is mainly due to uneven coating, so you'll need fine sandpaper and a bit of patience. First, lightly sand the repaired area with 1200-grit sandpaper dipped in water—don’t press too hard to avoid damaging the base coat; just sand until it feels smooth. Then clean the area thoroughly, ensuring no dust or grease remains—wiping with alcohol works even better. When applying the touch-up pen, avoid thick layers; instead, apply two or three thin coats, letting each layer dry completely (about 5–10 minutes). Once dry, lightly polish the area by rubbing in circles with a soft cloth to remove any burrs. If you're still unsatisfied, add a layer of clear leveling compound or car wax to enhance the shine. The key is to take your time—don’t rush the process, or you might make it worse. With a bit of practice, you’ll find DIY car repairs quite reliable and cost-saving.

When unevenness appears after using a touch-up pen, the first step is to check if the surface is clean, as residual dirt can cause uneven paint application. I recommend wiping the area clean with a cleaner first, then using your fingertips to feel the height differences and identify areas that need attention. Next, gently sand the raised areas with a fine sanding pad or sandpaper, being careful not to overdo it to avoid damaging the paint. After sanding, apply a leveling compound to fill in minor depressions, then use the touch-up pen once it has cured—applying thin coats multiple times is key. After drying, the polishing step is crucial; I achieve a smooth finish by using an electric polisher at low speed. Remember to work in a cool, dry place, as high temperatures can cause the paint to shrink and harden quickly, making repairs more difficult. Finally, regular inspection and maintenance can extend the repair's lifespan and ensure overall paint consistency. This method is suitable for small-area repairs, but for extensive damage, consulting a professional is advisable.

As someone who drives frequently, I handle minor paint scratches myself. If the touch-up pen leaves an uneven surface, the simplest method is to lightly sand the raised areas. Prepare a piece of fine sandpaper, spray some water to moisten it, then gently rub back and forth in small sections without applying too much pressure. Afterward, wipe it clean and reapply the touch-up pen, adding a thin layer and letting it dry before applying a second coat. If it feels tedious, adding some polishing compound and manually buffing can save a lot of effort. Throughout the process, pay attention to cleanliness and patience, and avoid working in dusty areas to prevent particles from sticking. Small repairs save money and time, but safety comes first—ensure the paint surface is smooth and doesn’t obstruct visibility before turning on the headlights at night.
