The treatment method for rusting the automobile chassis is: 1. Raise the car, wash the chassis with a high-pressure water gun, and first apply the engine external cleaning agent or engine degreaser to remove the oil sludge and sand bonded on the chassis; 2. Blow out the water in the gap with a water blow gun, and wipe the water dry with a towel; 3. When preparing to spray the anti-rust treatment layer, first cover the tire and exhaust pipe with masking paper and tape; 4. Spray the chassis anti-rust materials to the chassis in turn; 5. The coating is partially repaired to ensure that the stronger the shading, the better; 6. Remove the surrounding masking objects, clean the surrounding non-sprayed parts with a special detergent, and wait for the air to dry.

One. Be wary of small scars. In addition to common collisions and scratches, the tires bounce up small stones on the paint surface when driving, which will also make the paint surface peel off small spots, which will produce small rust spots after a long time.

Therefore, it is necessary to regularly inspect the car body, engine compartment cover and the surrounding area of the body, and once found, it is necessary to go to a professional beauty shop in time to deal with it.

Two. Check the humidity of places prone to water accumulation. While the vehicle is driving, it is inevitable to encounter rain and snow or pass by muddy and waterlogged roads, and some voids such as the bottom of the body and the floor of the car are prone to accumulate sludge.

Therefore, the inner and outer edges of the wheels, the bottom corners of the doors and trunks, the keyholes of the doors and the movable parts of the wiper rack should be checked frequently, and at the same time ensure the smooth drainage holes of the doors and body parts, and check the humidity of the covering in the car, such as carpets, to prevent rust of the floor parts.

Three. The soft lacquer surface is used as a sealing glaze. Some vehicles with soft paint may cause fine coercion marks when wind and sand particles hit the body during high-speed driving.

In this case, the body can be sealed glazed or coated, and the chassis can be armored or sealed for the bottom of the vehicle to protect the chassis from acid rain and corrosion, so that the original protective layer is not easy to dry out and fall off, and it can also prevent the impact of small stones on the chassis during driving.

Four. It's best not to cover the car jacket. If the vehicle is parked outdoors in windy and rainy weather, the inner layer of the car coat will repeatedly whip the car paint, especially if the wind and sand blow into the car coat, it will draw countless small scratches on the car body, and the paint will be black for a long time.

In addition, do not use a duster or rag to clean the sand particles on the car body directly after the wind and sand, but should rinse with clean water.

Five. The touch-up pen can be used to deal with coercion. If the rust is not very serious, you can use very fine water sandpaper dipped in water to gently grind away the rust spots, 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. If it is a new scratch, wipe it off and apply the primer directly. If the vehicle is equipped with a small can of original paint, you can wait for the primer to dry and then smooth it with sandpaper, and apply the original paint to the primer.

If there is no original paint, you can use a touch-up pen to color.

Six. Applying toothpaste can temporarily prevent rust. If you notice a new small scar, gently rub the toothpaste in a circle and apply it to the scratch.

Apply it again after rain or car wash. This generally reduces scratch marks and simply acts as an insulating barrier to prevent rust, with white paint being the most noticeable.

The solution to rust on the car chassis is: polish it directly, and choose some better anti-rust and waterproof coatings to repair it. Anti-rust and waterproof is a kind of compound coating based on rubber, wax, mineral oil and non-ferrous metals, which can effectively control the formation of rust spots on the metal surface.

The automobile chassis is composed of four parts: transmission system, driving system, steering system and brake system. The role of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. The drive train is generally composed of a clutch, a transmission, a universal transmission, a final reducer, a differential, and a half shaft.

Step 1: Raise the car, rinse the chassis with a high-pressure water gun, first apply the engine exterior cleaner or engine degreaser, remove the oil sludge and sand bonded on the chassis, or use special sandpaper to polish off the original anti-rust layer.

Step 2: Use a water blowgun to blow out the water in the gap and dry the water with a towel.

Step 3: When preparing to spray the anti-rust treatment layer, you must first cover the tires and exhaust pipes with masking paper (mostly newspapers) and tape, especially the sensors and shock absorbers on the car body.

Step 4: Spray the chassis anti-rust material to the chassis in turn, spray at least 3 layers, with a thickness of about 3 mm (the national operating standard is 4 to 5 layers of material).

Step 5: Partial repair of the coating to ensure that the greater the opacity, the better.

Step 6: Remove the surrounding masking and wash the non-sprayed parts of the perimeter with a special detergent and wait for air to dry, about 4 to 5 hours. According to reports, the entire chassis rust prevention process takes about 7 to 8 hours.

The chassis is the part closest to the ground, and it is particularly seriously affected by road conditions. During the driving process, it is affected by sand and gravel splashing, uneven and convex road support, rain and snow rust, and the service life is greatly shortened. When I held it up during maintenance, I saw that the chassis had been rusted. In the rainy season, acid rain.

The accumulation of stagnant water, combined with the salt contained in the air, makes it easier for the chassis of the vehicle to rust.

To prevent rust on the chassis, the owner should try to air dry or blow dry the chassis after washing the car.

The chassis armor is sprayed with a layer of polymer of about 5 mm at the bottom of the car, and after solidification, it protects the chassis like armor, which can effectively prevent rust.

1.If the overall embroidery of the chassis is serious, it can only be scrapped, and if it is only partially corroded, it can be welded and repaired.

2.It is recommended that the owner can come to a professional beauty shop for anti-rust care, and the anti-rust material should be evenly applied to the coating during the care, and only wait for natural air drying after all the completion is completed.

3.It is believed that every driver does not want their vehicle to be scrapped early, so if the above preventive operations can be done well, the use time of their vehicle can be increased.

Summary. Hello <>

For the treatment of rust on the chassis of the car, there are the following methods:1Cleaning & Rust Removal:

First of all, the surface of the chassis is thoroughly cleaned to remove sediment and impurities. Then use a wire brush or sandpaper to wipe the rust off until the metal surface is exposed. Be sure to keep the chassis dry.

2.Anti-rust coating: After cleaning and rust removal, a special layer of anti-rust paint or primer can be applied.

These products are able to form a protective layer that prevents the chassis from rusting again. 3.Primed and painted:

If the rust of the chassis is more severe, you can consider a chassis rebuild. First, a primer is applied and then paint is applied to restore the chassis to its original color and shine. 4.

Regular inspection and maintenance: In order to prevent the chassis from rusting, regularly check the chassis for signs of rust and deal with it in time. Otherwise, keep the chassis dry and clean and avoid exposure to moisture.

For the treatment of rust on the chassis of the car, there are the following methods:1Cleaning & Rust Removal:

First of all, thoroughly clean the surface of the chassis to remove sediment and impurities. Then use a wire brush or sandpaper to wipe the rust off until the metal surface is exposed. Be sure to keep the chassis dry.

2.Anti-rust coating: After cleaning and rust removal, a special layer of anti-rust paint or primer can be applied.

These products form a protective layer that prevents the bottom tray from rusting again. 3.Primed and painted:

If the rust of the chassis is more severe, you can consider a chassis rebuild. First, a primer is applied and then paint is applied to restore the chassis to its original color and shine. 4.

Regular inspection and maintenance: In order to prevent the chassis from rusting, regularly check the chassis for signs of rust and deal with it in time. Otherwise, keep the chassis dry and clean and avoid exposure to moisture.

Chassis rust is caused by prolonged exposure to moisture or because of corrosion of the chassis caused by snow melting agents and chemicals used on the road surface. In addition to the above methods, the following points are also worth it:1

Prevent moisture: Avoid parking your car in a damp place and try to choose a dry and ventilated parking lot. If it must be parked in a humid environment, a waterproof chassis cover can be used for protection.

2.Apply rust inhibitor: Regularly apply some rust inhibitor or anti-corrosion Sailbi chain etching oil, which can effectively delay the rate of rust on the chassis.

3.Choose the right route for Huisui: Avoid roads that use a lot of snow melting agents, which can easily corrode the chassis.

Anyway, the chassis rust needs to be dealt with in time to ensure the safety and longevity of the vehicle. Regular inspection, cleaning, and maintenance are key to preventing rust in the chassis.

Under the front wheels, for example, what glue is used in the marking department in the picture above.

Glue with preservatives, pro.

Can sheet metal glue be used.

Yes, dear.

Now, in order to prevent the chassis from rusting, the chassis protection is done after buying the car, commonly known as chassis armor. If it has rusted, you can go to the auto repair shop for rust removal. It's also relatively simple, remember to do protection after rust removal. Don't worry too much.

There are two ways to deal with the problem of Mercedes-Benz E-class chassis corrosion. Traditionally, composite coatings can be applied to metal surfaces. One of them is a composite coating agent based on rubber, wax, mineral oil, non-ferrous metals, etc., which can effectively inhibit rust on the metal surface, and has the advantages of elasticity, alleviating the impact of gravel, sound insulation, heat insulation, strong adhesion, and long oxidation resistance.

However, due to the characteristics of the material and driving safety, it is not allowed to spray on the heat shield, exhaust pipe, oil pipe, braking system, universal joint and heat dissipation box. Another material is a translucent wax-based composite film, which has an activation effect and forms a chemical glue on the metal surface, which acts as a film on the metal surface and can block moisture contact. For the treatment of chassis rust, the first task is to go to a regular store with a professional construction site and professional construction technicians.

At the same time, after the armor is completed, the owner must ask the construction shop for the chassis anti-rust hand cover worker quality assurance certificate to protect their rights and interests. Regular stores basically promise 1-3 years of quality assurance, and the losses caused by bottoming out and other reasons during the period can be repaired free of charge. The steps to deal with rust in the chassis are:

If it rusts, remove the rust first. The way to remove rust is direct sanding. Then, choose a better anti-rust and waterproof coating for repair.

At the same time, it should be noted that the same type of paint is used to prevent rust from Bichang. When carrying out chassis rust prevention care, pay attention to the chassis care location chosen by the owner. Some auto repair shops use anti-rust materials that are low-end, and the uniformity of the coating when applied is unreliable.

Therefore, it is necessary to find a more professional car repair shop or 4S shop to achieve excellent results. Coating uniformity is extremely important in the process of anti-rust treatment of chassis. If the coating is uniform, the anti-rust coating will not fall, but if the coating is uneven, a large area of anti-rust paint will fall off.

After the anti-rust material is cared for, it should also be air-dried naturally, and it cannot be immediately driven on the road of the car to achieve a more effective effect.

Hello, the treatment method of rust on the automobile chassis is: 1. Remove the rust first: the way to remove rust is relatively simple, just polish the wax and rot, and then choose some better anti-rust and waterproof coatings to repair.

When carrying out anti-rust work of automobiles, it is best to pay attention to the use of anti-rust and use the same type of paint. 2. When carrying out chassis anti-rust care, whether the quality is excellent depends entirely on the chassis care place chosen by the owner, and if you want to have an excellent effect in this protection process, that is, find a 4S shop or a more professional auto repair factory to do it. 3. In the process of chassis anti-rust treatment, whether the coating is uniform is extremely critical, and there will be no anti-rust paint falling off in the case of uniform coating.
