What to do with the spots left after the car paint surface has been sprayed over 84?

Limescale spots on the surface of car paint:

Limescale spots and acid rain are the most common damage to the car surface. Due to the fusion of many corrosive substances in acid rain, the light will make the paint surface oxidized, lose its luster, and become dull; Heavy will cause pimples on the smooth surface. Black cars are fine, but white or light-colored cars will have black spots, and the car surface will turn yellow and cracks.

Similarly, the fruit or flower juice that falls from the tree. For these stains, as long as they are found in time, rinsed with clean water, and then waxed, the paint surface can be guaranteed to be as clean as new.

Nowadays, many car owners park their cars in underground parking lots. The water droplets leaked from some pipes and air conditioners have great corrosion to the car surface, and are easy to oxidize to form white spots, which are difficult to clean. At this time, it is necessary to use sanding paper specially designed for car washing.

Cost: 100-300 yuan for ordinary cleaning, 600-800 yuan for grinding.

Other stain cleaning methods on the surface of car paint:

Driving your car in the city is a great pleasure for car owners. However, you may encounter some problems when the car is in the middle of the car and after it is parked, such as a pile of bird droppings on the hood at some point, and some hard-to-wash asphalt on the body at some point, all of which can be more annoying. How can you clean the dirt in a timely and effective manner without damaging the paint and restoring the beauty of your car?

Guano. It is not uncommon for car owners to park their cars in the shade of trees for fear of exposure to the sun, only to end up with bird droppings. Guano is a kind of biological excrement, relatively speaking, the composition is relatively simple, not very corrosive, and easy to clean.

However, there are two types of processing. If you find it quickly, you can use water to tap it and wipe it with a softer rag or paper towel; If it is found for a long time, it must be treated with crystal wax and beauty wax.

Cost: If you need to wax, the cost is about 100 yuan.

Because there may be some hard particles in the bird droppings, such as undigested husks, etc., if you wipe them directly with a paper towel, it is easy to scratch the car surface. Therefore, it must be dissolved with water before proceeding to the next step of treatment.

Bitumen. In the hot summer, the asphalt on the road surface melts when it is heated, and it is easy to splash on the car surface. If the condition is not severe, you can use an asphalt cleaner to melt it on the dry asphalt and then dry it with a rag.

If the body has been exposed to the sun, due to the action of sunlight, the asphalt has penetrated into the inside of the paint surface and produced a corrosive effect, which requires a professional to judge the damage. Generally speaking, you will try it with polishing wax first, and if you can't remove it, you will need to wipe it with a professional car matte paper.

Cost: If waxing can be processed, about 300-400 yuan; If you need sandpaper for car washing, the cost is higher, more than 600 yuan.

1.Automotive paint films are invaded, adhered and stained by dirt and harmful substances in the air. 2.The pigments in the paints used are not resistant to acids, alkalis or mildew. 3.The car spray paint film is soft, viscous or has been used and destroyed, and there is foreign matter precipitation in the training process.

Prevention and control methods of automobile paint spots;

1.Choose paints with good stain resistance;

2.Avoid placing coated items near pollution sources such as acids and alkalis;

3.Do not use coatings that are softened, sticked, or precipitated by heat.

If the rusty car can be repainted, first remove the rust to prevent rust in the first trim, and then repaint

1.The surface of the body-in-white produced by the welding workshop has various oil stains, welding slag, dust, etc. The pre-treatment process is to treat these stains so that the body meets the requirements of electrophoresis.

At the same time, the body-in-white is phosphated to form a protective layer on the surface of the body to increase the adhesion, corrosion resistance and moisture resistance of the paint film.

2.The paint and varnish on the outermost side of the car are collectively referred to as topcoats, and paints and varnishes work differently. The base paint brings a splash of color to the interior of the car, showing the personality of the car interior, while protecting the intermediate coat and the electrophoretic primer.

The varnish layer has the functions of anti-pollution, anti-acid rain and anti-ultraviolet rays, which can better protect the pigment. The outermost layer of the car that we can touch is the varnish layer.

3.After the topcoat is sprayed, it is dried, dried, and cooled before entering the final quality inspection process for post-processing. Generally, polishing wax is used to polish the surface of the car, which can make the topcoat have a soft and stable luster.

Millions of car purchase subsidies.

1.Automobile spray coating film is subject to the invasion, adhesion and contamination of dirt and harmful substances in the air. 2.The pigments in the paints used are not resistant to acids, alkalis or mildew. 3.It is caused by softness, re-adhesion or precipitation of foreign matter during the use of automobile spray paint film.

Prevention and control methods of automobile paint spots:

1. Choose coatings with good stain resistance;

2. Avoid placing the coated items near pollution sources such as acid and alkali;

3. Do not use coatings that are soft when heated, sticky or precipitate foreign substances.

If the car is rusty, it can still be repaired, first remove the rust to prevent continued rust, and then re-paint:

1. There are various oils, welding slags, dust, etc. on the surface of the body-in-white generated in the welding workshop, and the pre-treatment process is to treat these stains to make the body meet the requirements of electrophoresis. At the same time, the body in white is phosphated, the purpose of which is to form a protective layer on the surface of the body to increase the adhesion of the paint film and the resistance to corrosion and moisture.

2. The outermost color paint and varnish of the car are collectively called topcoats, and the roles of color coats and varnish are also different. The base paint gives the car a colorful outfit that shows off the individuality of the car while protecting the middle coat and the electrophoretic primer. The varnish layer has the functions of pollution resistance, acid rain resistance, ultraviolet protection, etc., which can better protect the color paint, and the outermost layer of the car we can touch is the varnish layer;

3. After the topcoat is sprayed, it is dried, dried and cooled into the final quality inspection process for post-processing. Generally, polishing wax is used on the surface of automobiles, which can make the topcoat coating have a soft and stable luster.
