Is the repair mark obvious when using a touch-up pen?

Using a touch-up pen to repair car paint scratches can yield decent results, but there will still be some color difference. Additional information is as follows: 1. Paint may peel off: There is indeed a possibility of paint peeling when using a touch-up pen for repairs. This is because the paint coating process used in car manufacturing is far more complex than simple application—not only are the paint materials different, but the coating process is also very rigorous. Many vehicles require high-temperature baking to dry the paint film. The higher cost of repairs at a 4S shop is due to the use of original factory paint and an attempt to mimic the coating process, ensuring better paint fusion and preventing subsequent peeling. If a touch-up pen is used directly, peeling may occur, especially if the steps are incorrect—such as failing to clean the car surface, applying too much paint, or exposing the car to excessive heat. The paint may peel off, and the car could later develop rust. 2. Limited application area: The repair effect of a touch-up pen is also quite limited, suitable only for very small and minor scratches. For car owners who want to avoid peeling, self-spray paint can be a better option. The advantage of self-spray paint is that it can evenly cover the car surface. When applying, maintain a slightly greater distance and use multiple layers until the new paint blends seamlessly with the original car paint, thus preventing peeling.
When I used a touch-up pen to repair car scratches, I realized that the visibility of the repair completely depends on the technique and preparation. If the paint color doesn't match or too much is applied, it can look very obvious because excess paint builds up and forms raised areas. The first time I tried it without experience, I ended up with noticeable color differences and an uneven surface. Later, I learned to first clean the scratched area, smooth it with fine sandpaper, then choose a pen that matches the original paint, apply thin layers, letting each dry completely before adding the next, and finally polish it lightly. This way, the scratches become almost invisible. The key is to test on a small area first to avoid mistakes. The whole process is quite tedious, but it saves money—professional spray painting is flawless but much more expensive.
The touch-up pen repair marks can sometimes be quite noticeable. In my opinion, this depends on the size and location of the scratch. If the scratch is in a recessed area of the paint or is small in size, it won't be easily detectable when handled properly. However, for large flat surfaces or deep scratches, there might be uneven color or slight color differences after touch-up, especially when viewed under sunlight. My suggestion is to always choose a high-quality pen and perform a color matching test. Clean the surface and dry it with a soft cloth before applying thin layers—avoid rushing with thick coats. Also, control the working environment; avoid humid or dusty conditions to prevent impurities from mixing in. Paying attention to these details can make the repair results closer to professional standards.
