4hw.com.cn: a lot of friends love their cars. A little bumps and scratches will be very painful. However, in rainy days or after washing the car, you should pay attention to the problem of car rust. Then how to prevent the car from rusting? Let's teach you some tips on how to prevent the car from rusting.
1. Frequently check the humidity at the place easy to accumulate water.
Sludge is easy to accumulate in some spaces such as the underbody and the floor in the car. If the owner does not clean it in time, the moisture will be hidden. Therefore, for the inner and outer edge of the wheel hub, the bottom corner of the door and the trunk, the key hole of the door and the movable part of the wiper frame, etc., it is necessary to check frequently, keep the drainage holes of the door and the body unblocked, check the humidity of the interior covering, such as the carpet, etc., and prevent the floor parts from rusting.
2. Watch out for minor scars.
The paint surface is often rusted. In addition to the common collision and scratches, the small stones springing up from the tires when driving will hit the paint surface, which will also make the paint surface appear small peeling spots. After a long time, small rust spots will appear. And these small scars are easy to be ignored because they are mostly in the inconspicuous place. Therefore, we should regularly check the car body, engine compartment cover and all around the car body. Once found, we should go to a professional beauty shop in time for treatment.
3. It's better not to cover the car.
When the vehicle is parked outside, in case of windy and rainy weather, the interior layer of the car clothes will repeatedly draw the car paint, especially if the wind sand blows into the car clothes, countless small scratches will be scratched on the car body, and the paint will be blackened after a long time. In addition, do not use a duster or rag to clean the sand on the car body directly after the sandstorm. Instead, wash it with clean water. It is also to prevent the sand on the duster and rag from scratching the paint surface.
4. Make sealing glaze for soft paint surface.
Some vehicles with soft paint surface may also cause fine entrainment marks when sand particles hit the vehicle body during high-speed driving. For this kind of automobile, the body can be sealed with glaze, which can form a network of solid protective film, improve the hardness of the paint surface, and the effect can be maintained for about a year. And coating can achieve similar effect. In addition, the chassis can be armored or plastic sealed at the bottom of the vehicle, which can protect the chassis from acid rain and corrosion, prevent the original protective layer from cracking and falling off, and prevent the impact of small and medium stones on the chassis when driving.
5. The touch up pen can handle scratches.
If the rust is not very serious, the rust spots can be removed by gently dipping a very fine water sandpaper in water. However, random grinding without direction shall be avoided, and the same direction shall be polished in a straight line. When it is completely wiped, apply a layer of primer. If it is a new scratch, the primer can be applied directly after wiping. After that, if the vehicle is equipped with a small tank of original paint, you can wait for the primer to dry, and then grind it with sandpaper, and apply the original paint on the primer. If there is no original factory paint, you can buy a touch up paint pen and use it for coloring. Although this kind of treatment is not as effective as going to the beauty shop, if it is a small or inconspicuous scar, it can also prevent the rust from expanding and aggravating.
6. The toothpaste can temporarily prevent rust.
When a new small scar is found, smear the toothpaste around the scratch. Don't forget to paint it again after the rain or the car wash. In general, this method can reduce the scratch mark, and also can simply play a role of isolation, prevent rust, no problem in a short time. Especially white paint, the most obvious effect.
