How to Remove Poorly Applied Car Touch-Up Paint?
2 Answers
Method for removing poorly applied car touch-up paint is to use a professional automotive paint cleaner. Preparation: Prepare a bottle of professional automotive paint cleaner. Professional cleaners can easily remove small touch-up compounds without damaging the car paint. Wiping: Use a cloth to gently wipe off the small touch-up compounds on the car paint surface, paying attention to the wiping pressure. Finally, the small touch-up compounds in the car paint will be cleaned off. Automotive paint mainly consists of four layers: the first is the electrophoretic paint, whose main function is rust prevention. The second is the primer, which resists UV rays and stone chips and provides a base for the color paint. The third is the color paint layer, primarily for aesthetics. The fourth is the clear coat, which gives the car body a glossy finish and resists stone chips.
I recently dealt with the same issue in my own garage. The key is to gently sand the touch-up area with 2000-grit wet sandpaper, keeping the surface moist to avoid overheating. After smoothing out any uneven spots, switch to 5000-grit sandpaper for fine polishing. Then, use polishing compound with a foam pad on a polisher, moving in steady circular motions – this step requires extra patience as uneven pressure can create new scratches. Finally, wipe clean with a microfiber cloth. If the base coat isn't exposed, this treatment should restore a smooth finish. If the damage has reached the primer, it's better to have it professionally repainted at an auto body shop.
