What to do if there are rust spots on the body of the car, and what to do if there are rust spots on

In addition to the common reasons, collisions, scratches, and long-term parking rust, there is also a situation that when driving, the small stones caused by the tires of the front car bounce off the point collision, which will cause the paint surface to peel off one by one, resulting in small rust spots. This is often overlooked, and the body, bonnet and surroundings of the car should be inspected regularly, and if found, they should be dealt with immediately.

In addition, places where the body is prone to water accumulation, such as the inner and outer edges of the wheel arc, the bottom of the door and the trunk, and the corners, are prone to rust over time. If the drain on the lower edge of the door is clogged or not smooth, moisture that seeps in during rain or driving will accumulate inside the door for a long time, and after a period of time, rust will start to grow from the inside out, and it will be difficult to deal with when you find it.

If the rust is not very serious, you can use very fine water sandpaper dipped in water to gently grind off the rust spots, wipe them off completely, and apply a layer of primer to ensure that the rust will not expand or aggravate. If it is a new scratch, it can be wiped clean and applied directly to the primer, and most vehicles are equipped with a small can of original paint. It's not pretty, but it's fine in a small place.

You can also buy a touch-up pen in advance, and after the primer is dry, smooth it with sandpaper, and then use a touch-up pen to color. Remember, the primer has the effect of preventing rust and increasing the adhesion of the topcoat, don't be lazy and apply it directly with a touch-up pen. Small bruises or inconspicuous areas can be modified in this way.

If you really want to be lazy, you can also use toothpaste. I put a tube of ordinary toothpaste in the car, and when I found a small new scratch mark, I applied a little casually.

If it's just symptomatic, it's to remove the rust spots and then add new paint;

But the key is how to cure the root cause;

First of all, why do rust spots occur? My personal understanding should be: after the protective paint on the surface of the car is scratched, the metal under the car is exposed to the air for a long time, and the surface is oxidized due to moisture, rain and other reasons, resulting in the formation of rust spots;

So the key is to look at your usual own maintenance, if as you describe yourself, 'love the car', then you should usually pay attention, when there are scratches, judge, if the scar is relatively deep, has exposed the bottom color of the car, then at least use a paint pen to make up.

Workaround:

01. Car wash mud: Car wash mud is also called car wash to remove sludge, which can be used to scrub the surface of the body when washing the car. It is a kind of paint that does not damage the car paint, can remove stubborn stains on the surface of the body, if you want to remove the rust spots on the white car paint, you need to rub it back and forth a few times more vigorously during use until it is clean.

02. Polishing: If the car wash mud cannot remove the rust spots of the white car paint, it can be removed by polishing, and the polishing can also remove slight scratches on the body.

03. Touch-up paint: If the above two methods can't go out of the white car paint rust spots, the car is really exposed to the primer, at this time, you can polish it a little, and then use a white touch-up paint pen to lightly point the paint.

04. Methods to prevent rust spots in white cars: wash the car frequently, do a good job of helping with car paint, waxing, glazing, coating, crystal plating, etc. Don't park under a tree.

Many trees secrete gum, which is difficult to handle when stuck to the car. There is also the need to wash the car immediately after rain, and 90% of the rust spots on the body are caused by the acidic substances in the rain.

What should I do if there are rust spots in the body paint? In this case, it is enough to go to the 4S store for a beauty treatment.

Rust spots on the surface of the car body are caused by fine iron particles – industrial scatters that float in the air – fall and stick to the surface of the car body.

This kind of iron particles adhere to the car body for a long time, due to the action of air and rain, the surface of the body produces rust spots, if the rust spots are not eliminated, it will even erode the paint, resulting in the corrosion of the base metal. Therefore, the rust spots on the surface of the body should be repaired and maintained.

According to the mechanism of rust spots on the surface of the body, it can be seen that doing a good job in the daily maintenance of the car, washing the car frequently, and keeping the body clean are powerful measures to prevent the occurrence of rust spots on the surface of the body.

Rust spots are caused by acid rain corrosion. With wax, you're done. Generally, wax is done once every 2-3 months.

Waxing is to get out of the sun and protect against ultraviolet rays. Rain, acid rain. After the car wash, there will be a lot of small scratches on the car paint.

Small dots. Dirt and stuff like that. Pay attention to maintenance.

Avoid car paint, you should pay attention when washing your car:

1. Do not wash your car under the scorching sun. This leaves dry water beads on the body.

2. Do not wash the car in very cold weather. Once the water freezes, it can cause the paint film to break.

3. Do not wash the car after the end of the engine is completely cooled down. This can cause the engine to age prematurely.

4. Do not add detergent indiscriminately. Laundry detergents, detergents and low-quality soaps are not allowed when washing. Because these detergents contain alkali, it may wash away the grease in the paint surface and accelerate the aging of the paint finish. Generally, no detergent is added when washing the car.

Rust under the seat: It is recommended to go to the 4S store as soon as possible for inspection and treatment. If rust is found, it should be removed as soon as possible and rust prevention treatment should be done to avoid further rust.

Here's how to prevent rust in your car:

Check the humidity of places prone to water accumulation.

For the inner and outer edges of the wheels, the bottom corners of the doors and trunks, the keyholes of the doors and the moving parts of the wiper rack, etc., it is necessary to check frequently, and at the same time, keep the drainage holes of the doors and body parts unblocked, and check the humidity of the covering in the car, such as carpets, to prevent rust on the floor parts.

Watch out for small scars.

In addition to the common collisions and scratches, the small stones that bounce up the tires when driving hit the paint surface, which will also make the paint surface peel off one by one, and small rust spots will occur after a long time. Regularly inspect the car body, engine compartment cover and body surroundings, and if found, go to a professional beauty shop for treatment.

Don't cover your car coat.

When the vehicle is parked outdoors, if it is windy and rainy, 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 scratch countless small scratches on the car body, and the paint will be black for a long time. And after the wind and sand, do not directly use a duster or rag to clean the sand particles on the body, but should rinse with clean water, which is also to prevent the sand particles on the duster and rag from scratching the paint surface.

The soft lacquer surface is used as a sealing glaze.

Some cars with soft paint can glaze the body to form a solid protective film in the form of a network to improve the hardness of the paint surface, and the effect can be maintained for about 1 year.

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.

After the primer is dry, it is smoothed with sandpaper and the original paint is applied on top of the primer. You can also buy a touch-up pen and use it for coloring.

Applying toothpaste can temporarily prevent rust hair.

If there are new small scratches, gently rub the toothpaste in circles and apply it to the scratches. Don't forget to apply it again after rain or car washing. This generally reduces scratch marks and can simply act as an insulating barrier to prevent rust.

Park your car indoors as much as possible.

Although the car body is treated with anti-rust, if the surface coating of some bolts is damaged, it is easy to rust when exposed to water. Therefore, it is beneficial to ensure that the vehicle is parked in a dry environment, especially for long periods of time.

The face of the car is the sheet metal paint, and the main culprit of the rusty paint is the moisture hidden in the paint holes.

Solution: If it's just a slight scratch or rust, we can do it ourselves. Use very fine water sandpaper dipped in water to gently grind away rust, 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. New scratches were found and can be applied directly with a touch-up pen.
