How do you remove white spots in the paint in a car?

In the face of weak adhesion of white spots, first use a rag to wipe off the dust and foreign objects with little adhesion around the white spots, and in order to avoid damaging the car paint, use plastic film and other items with relatively small hardness to gently scrape off the white spots.

The reason is that black cars are generally in a bright black state, and when the light hits the black paint, it will produce mirror reflection, especially at night, the black car paint makes the car look very translucent and high-end.

However, this sense of luxury is based on the condition that the paint is clean, and once the surface of the paint is stained with dust or paint, the reflective effect of the paint is instantly reduced. And because the dust is generally light white, it adheres to the body and forms a huge contrast with the black paint, at this time, the car not only loses its luster, but also becomes particularly dirty.

Here's how to remove white spots from black paint:

1. Decontamination wax;

2. Fast-acting decontamination wax;

3. Shellac sticky remover;

4. Alcohol wipe;

5. Car washing mud.

Among them, car wash mud is the worst choice, car wash mud is actually very easy to use, if there is surface sap, when the hand touches the yarn paper, use car wash mud to get it all in a few clicks, and there are a few days of rainy days without washing the car paint surface There is a Tuotuo's color markings, like oxidation, decontamination wax, shellac can not be washed off at all, with car wash mud slowly a little longer can be removed, but only for this small white spot car wash mud is useless, because of not giving up, with car wash mud kept rubbing on the small white spot, but afterwards left a lot of dark lines, At this time, I don't dare to use scratch wax, which will leave a foggy piece after using the scratch wax, and it can't be covered after hitting the platinum wax.

The method is as follows: 1. Decontamination wax; 2. Fast-acting decontamination wax; 3. Shellac sticky remover; 4. Alcohol wipe; 5. Car washing mud. In fact, the reason why there are white spots on the black car paint is very simple, that is, because the black car paint is not resistant to dirt.

Since black cars are generally in a bright black state, when the light hits the black paint, it will produce mirror reflection, especially at night, the black car paint makes the car look very translucent.

1. Car washing mud.

Most of the rust spots are only found on the surface of the car paint, which can be scrubbed with car wash mud. Car wash mud has an abrasive effect to remove stubborn stains from the surface of the car body. For the white car paint rust spots, you need to wet the car body first, and then use car wash mud, the car wash mud should be soaked soft, and the rust spots on the car should be evenly rubbed and wiped back and forth to keep the body wet.

2. Polishing. If the car wash mud can't remove the rust spots of the white car paint, it can be removed by polishing, and the polishing can also remove minor scratches on the body, but you need to pay attention to the polishing strength.

White paint maintenance.

1. a car cover. If the car is often left outdoors and not in use, you can buy a car cover, and when you are not driving, you can use the car cover to cover it, which can also protect the paint surface of the car to a certain extent.

2. Shaded place.

The paint surface of a white car is prone to oxidation and yellowing, so when parking, you should also find a shady place and do not let the sun shine directly on the car, so as not to turn the paint of the car yellow.

There are four methods of derusting the surface of automobiles: manual treatment, mechanical treatment, chemical treatment and flame treatment.

1. Manual processing.

Manual treatment mainly uses shovel blades, wire brushes, abrasive cloths, broken hacksaw blades and other tools, relying on manual knocking, shoveling, scraping, brushing, sanding methods to remove rust, this is the traditional rust removal method of lacquer workers, but also the most simple and feasible method, there is no restriction on any environment and construction conditions, but because the efficiency and effect are too poor, can only be applied to a small range of rust removal treatment.

2. Mechanical rust removal method.

The mechanical rust removal method mainly uses some electric and pneumatic tools to achieve the purpose of removing rust.

Commonly used power tools such as electric brushes and electric grinding wheels; Pneumatic tools such as pneumatic brushes. Electric brushes and pneumatic brushes use the rotation of special circular wire brushes to remove rust or oxide scale by impact and friction, especially for surface rust, the effect is better, but it is difficult to remove deep rust spots. The electric grinding wheel is actually a portable grinding wheel, which can be moved at will in the hand, and the high-speed rotation of the grinding wheel is used to remove the rust spots, which has a good effect, especially for the deeper rust spots, its work efficiency is high, the construction is high, and it is easy to use, which is an ideal rust removal tool.

However, care should be taken not to penetrate the metal skin during operation.

3. Sandblasting and shot blasting treatment.

Sandblasting and shot blasting are the same as the previous method of removing old paint film.

4. Flame treatment method.

The flame treatment method is to use a gas welding torch to burn a small number of deep rust spots that are difficult to remove by hand, so that the high temperature can change the chemical composition of the rust oxide to achieve the purpose of rust removal. With this method, care must be taken not to burn through the metal surface and to prevent the thermal deformation of a large area of the surface.

5. Chemical treatment method.

The chemical treatment method is actually a pickling and rust removal method, which uses an acidic solution to react with metal oxides (rust) to form salts, which are separated from the metal surface. Commonly used acidic solutions are: sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid.

During the operation, the acidic solution is applied to the rust part of the metal and let it slowly react with the rust to remove it. After the rust is removed, it should be rinsed with clean water, and neutralized with a weak alkali solution, and then rinsed with clean water and wiped dry and dried to prevent rust soon.

The pickled metal surface needs to be roughened or phosphated, mainly to increase the adhesion between the metal surface and the primer.

When diluting concentrated sulfuric acid, the sulfuric acid should be poured into the water of the container slowly, and stirred constantly, and the reverse operation should not be reversed, so as to avoid the sulfuric acid liquid splashing out and hurting people.

Car wash mud can be washed off.

Generally, rust spots appear on the car, all because the car was accidentally scratched and the paint was rubbed off. Then the car was exposed to the sun and rain before rust spots appeared.

When encountering rust spots in the car, you first need to use fine sandpaper dipped in water for sanding. Note that those who are not good at the level should polish it on a small scale.

Once sanding is complete, apply primer. Primers can act as a very good barrier.

Once the primer has dried, apply a touch-up pen.

If you're in a hurry and don't have a ready-made primer or touch-up pen on hand, you can treat it with white nail polish or corrective fluid after sanding.

As a special reminder, the small dots on some white cars that look like rust spots are not necessarily rust spots, they may be asphalt, or other dirty things.

Theoretically, it shouldn't be a rust spot, or a large gum or something.

It is recommended to buy a bottle of gum cleaner, Dr. Turtle or something, about 30.

Friends of the new Suo Ba full of "rust spots", was flickered by the whole car polishing, did not solve, and finally I suggested buying a bottle of gum cleaner to wipe it off with a spray.
