Will the car paint rust if it falls off, and what should I do if the car body paint has rust spots?

If it's just scratches, it won't. If the primer has been rubbed off to reveal the iron sheet, then the paint must be touched, otherwise it will rust.

Go to a car detailing shop or 4S shop to do partial touch-up or repaint. Maintenance of car paints:

1.Before, during and after the use of the vehicle, the dust on the vehicle body should be removed in time to minimize the adsorption of dust by static electricity on the body.

2.Rinse promptly after rain. After the rain, the rain stains on the car will gradually shrink, so that the concentration of rainwater acidic substances will gradually increase, and if the rain stains are not rinsed with clean water as soon as possible, the topcoat will be damaged over time.

3.When washing the car, it should be done after the engine has cooled down, and do not wash the vehicle in the scorching sun or high temperature, so as not to leave traces of the detergent being dried. Usually use special detergent and neutral living water to wash the vehicle by yourself, and should not use alkaline laundry detergent, soapy water and washing spirit to prevent washing off the grease in the paint surface and accelerating the aging of the paint surface.

4.Use a clean, soft rag or sponge to prevent metal filings and sand particles from being mixed with the vehicle, and do not use a dry cloth, dry towel, or dry sponge to wipe the car to avoid scratches. When wiping, you should gently wipe from top to bottom in the direction of the water flow, and should not draw circles and wipe horizontally.

5.For some special traces of strong corrosiveness, it is necessary to remove them in time. In this regard, it must be cleaned with a special detergent, and it should not be scraped with a blade or eliminated with gasoline at will, so as not to damage the paint surface.

The face of the car is the sheet metal paint, and the main culprit of the rusty paint is the moisture hidden in the paint holes.

Solution: If it's just a slight scratch or rust, we can do it ourselves. Use very fine water sandpaper dipped in water to gently grind away rust, but do not grind in no direction, and polish in a straight line in the same direction.

Wait until it is completely wiped off and apply a layer of primer. New scratches were found and can be applied directly with a touch-up pen.

Workaround:

01. Car wash mud: Car wash mud is also called car wash to remove sludge, which can be used to scrub the surface of the body when washing the car.

02. Polishing: If the car wash mud cannot remove the rust spots of the white car paint, it can be removed by polishing, and the polishing can also remove slight scratches on the body.

03. Touch-up paint: If the above two methods can't go out of the white car paint rust spots, the car is really exposed to the primer, at this time, you can polish it a little, and then use a white touch-up paint pen to lightly point the paint.
