It will not rust after being repaired with a touch-up pen. A more effective method to deal with rust on the car paint surface is to first sand it clean with sandpaper, then use fine sandpaper with 1000 grit or higher to sand it again. After continuous sanding, repaint the area. If there is no rust on the paint surface and the surface oxidation is covered by the touch-up pen, as long as the coverage is complete and the galvanized sheet inside does not come into contact with air, it will not rust. A touch-up pen is a tool for repairing car scratches. By selecting the appropriate model that matches the original car paint color, you can perform the repair yourself. After applying the touch-up pen to small scratches or areas where the paint has peeled off, it conceals and fills in the scratches. The composition of the touch-up pen is generally the same as the original car paint.
I've used a touch-up pen to deal with minor scratches on my car several times. As long as you clean the area beforehand and apply the paint to cover the exposed metal, rust is unlikely to form. The key is to wipe away any dirt from the scratch and sand off any rust if present. When applying the paint, make sure to cover the area evenly without leaving gaps. For example, on rainy days, I usually wait for dry weather to do the touch-up and let the paint dry completely before driving the car. If you skip the cleaning step, rainwater can seep in and cause rust. A touch-up pen is a temporary solution, and in the long run, professional repair at a shop is safer. Remember these tips to save money and hassle.
