Will touch-up paint dry in 20 minutes?

Touch-up paint will not dry in 20 minutes, and the relevant explanations are as follows: Introduction: During winter, even in a high-temperature room at 50-60 degrees Celsius, it takes several hours for touch-up paint to dry completely. Preparation work: When performing vehicle touch-up painting, 4S shops typically advise owners to leave their keys and, accompanied by the owner, record the vehicle's mileage, fuel gauge reading, overall condition, and external scratches. The owner then confirms and signs the record. Additionally, they will remind the owner to remove any valuables from the car. Nowadays, most standard 4S shops are equipped with surveillance cameras, allowing owners to review the footage in case of lost items.
I've used touch-up paint pens to repair car scratches many times. It usually takes about 20 minutes for the surface to dry to the point where it won't transfer color when lightly touched, but this doesn't mean it's fully cured. In high temperatures with good ventilation, like in summer, it might dry faster, but it takes longer in damp winter conditions. Even when the surface seems dry, avoid washing the car or exposing it to high-speed wind immediately, as this can cause bubbling or peeling. I recommend waiting at least an hour before using the car to be safe, and it's best to leave the repaired area in a well-ventilated place after application. Additionally, choosing a high-quality touch-up pen can speed up drying—some fast-drying types are available—but it's crucial to read the product instructions carefully to avoid compromising the finish for the sake of speed.
