Rust often appears on the surface of car paint. In addition to common collisions and scratches, pebbles bouncing off tires during driving hit the paint surface, which will also cause peeling spots on the paint surface, which will produce small rust spots after a long time. These small scars are easily overlooked because they are mostly in inconspicuous places. Therefore, it is necessary to regularly check the car body, engine hood and around the car body. Once found, you should go to a professional beauty shop for treatment in time.

Tip 2: Check the humidity of water easily.

Vehicles will inevitably encounter rain and snow or pass through muddy and stagnant roads. Some gaps such as the bottom of the car body and the floor inside the car are easy to accumulate mud. If the owner does not clean it in time, it will hide moisture. Therefore, the inner and outer edges of the wheel hub, the bottom corner of the door and trunk, the key hole of the door and the movable parts of the rain scraper frame should be checked frequently, and at the same time, the drainage holes of various parts of the door and body should be kept clear, and the humidity of the car interior covering such as carpet should be checked to prevent the floor parts from rusting.

Tip 3: Seal glaze and soft paint.

Some vehicles with soft paint surface may also cause small scratches when sand hits the body during high-speed driving. For this kind of car, the body can be sealed with glaze, which can form a net-shaped solid protective film and improve the hardness of the paint surface, and the effect can be maintained for about one year. The coating can also achieve a similar effect. In addition, the bottom of the vehicle can be armored or molded, which can protect the chassis from acid rain and corrosion, make the original protective layer not easy to crack and fall off, and prevent pebbles from hitting the chassis during driving.

Tip 4: It is best not to cover the clothes in the car.

If the vehicle is parked outdoors, if it encounters windy and rainy weather, the inner layer of the car coat will repeatedly whip the car paint, especially when the wind and sand blow into the car coat, which will draw countless tiny scratches on the car body and cause the paint surface to be black over time. In addition, after the sandstorm, do not directly clean the sand on the car body with a rag or rag, but rinse it with clear water to prevent the rag and the sand on the rag from scratching the paint surface.

Tip 5 Do it yourself to deal with small rust spots.

For some slight scratches or rust on the car body, if the owner doesn't want it, it's not worth spending money on a car beauty shop. Then, the owner can do it himself and deal with it in some simple ways.

Tip 6 The finishing pen can handle small scratches.

If the rust is not very serious, you can first gently grind off the rust spots with very fine water sandpaper dipped in water, but don't grind them indiscriminately, but polish them in the same direction. After wiping completely, apply a layer of primer. If it is a new scratch, it can be cleaned and directly primed. After that, if the vehicle is loaded with small cans of original paint, you can wait for the primer to dry, then smooth it with water sandpaper and apply the original paint on the primer. If you don't have the original painting, you can buy a touch-up pen to color it. Although this treatment is not as effective as going to a beauty shop, if it is a small or inconspicuous scar, it can also prevent the rust from expanding and aggravating.

Tip 7 Toothpaste can temporarily prevent rust.

There is also a common toothpaste to deal with. When you find a new small scar, gently circle the toothpaste and apply it to the scratch. Don't forget to apply it again after it rains or washes the car. Doing so can generally reduce scratches and imprints, and can also simply play an isolation role to prevent rust, which is no problem in the short term. Especially white car paint, the effect is the most obvious.
