How long does it take for a car to rust when the paint comes off?The car rusted for several years

If the car paint is off and the car is not repaired, it will rust.

If the paint is damaged, you can't fix it for the time being, you can use nail polish.

Apply to prevent the exposed primer from rusting. It is not good to use correction fluid, because it will also be softened by blisters.

But it depends on whether you are ** off the paint, the door is much more expensive, and the bumper.

It's cheaper, if it's on the corner, you don't need to spray the whole piece, and if you want to spray it on other planes, you can't make up for it a little bit, you can spray it a little, and you can't spray it.

Extended information: The front and rear bars are made of resin material, which will not rust, just use a touch-up pen to dot it, fenders.

It is a metal material, which has touched the base paint, so this will rust, and it is not worth going to the painting repair in such a place, I personally recommend that the edges be sanded flat with fine sandpaper, be careful not to get wet, and then repair with a touch-up paint pen, and finally apply a layer of wax.

Insisting on drying is a very important and critical point in maintaining the car paint, and the dry body can keep the body of the car away from the trouble of rust. But the car is definitely going to get wet, so what should be done after it gets wet?There are no more than two paths to get wet, one is to wash the car and the other is to rain, rainy days.

There is no choice but to do a simple rinse of your car after the rain stops, and then dry it with a dry cloth.

After washing the car, you should also pay attention, many car friends think that after washing the car, the staff will wipe your car dry, but not many details can not be noted, so after washing the car, you should pay attention to the door, the lower edge of the body scuff strip, the fuel tank cover and other places that are easy to accumulate water, if there is stagnant water, you should dry it as soon as possible.

If it rains, the primer will rust for about 1 and a half months, and if it doesn't rain, it will rust in about 3 to 5 months, so it is recommended to dispose of it within a month. The easiest way to scrape the lacquer is to use a regular toothpaste and gently rub the toothpaste in a circle 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 also simply act as an insulating barrier to prevent rust in the short term, especially with white paint. If the part of the paint that has been rubbed off is not large, and the scratched area is not deformed or concave, the solution is to buy paint of the same color as the car paint and spray it yourself according to the instructions.

If you come into contact with some moisture, or some corrosive liquid. Generally, it will rust.

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.

After a car is manufactured and leaves the factory, its body is subjected to five to ten years or even longer, during which time the environment can be harsh.

Rust (oxidized) is the basic chemical property of many metals, which will occur slowly at room temperature, especially the steel materials commonly used in cars, once rusted, the iron oxide produced will adsorb water molecules in the air, causing more serious rust.

Notes:

The anti-rust treatment of cars is mainly focused on the body. The body that is in the manufacturing process is called the "body-in-white". During the manufacturing process of the body-in-white, anti-rust treatment is carried out using "cathode electrophoretic coating", but this does not prevent the occurrence of rust in the inner cavity.

When manufacturing components with cavities, wax injection holes are usually pre-empted.

Some closed parts will have holes to facilitate the flow of liquid wax when draining wax between wax drains. The body-in-white enters the wax filling section after passing through the various sections before the painting. Generally speaking, cavity wax injection can effectively prevent and prolong the time of cavity car body rust, but it can not completely avoid the essence of car body rust, generally speaking, 3 years of rust-free and 15 years of rust-free wear can be done.

Imported cars and high-end domestic cars do not hurt the paint surface, do not hurt the shell, and are not rusty for life. The welded shell of any vehicle will rust again within two years. Therefore, do not weld the shell of the car if it is not unsightly, this is the experience to remember.

Once the car shell is welded, it will be troublesome and endless.

It has a lot to do with the region and environment, personal driving habits, for example, if you are in the coastal area on 3-5 years of rust, it is easier to rust in places with a large temperature difference between day and night, and it is also easy to rust in the rain or sun.

If the paint of the car is not destroyed, it can be up to 15 years.

European cars will not rust for at least 8 years.

If you take good care of it, you will have no problem for 15 years.

It depends on what brand your car is!

It's related to your maintenance habits, it's hard to say

If the car paint is off and the car is not repaired, it will rust.

If the car paint is damaged and you don't want to or can't fix it for the time being, you can use nail polish to prevent the exposed primer from rusting. It is not good to use correction fluid, because it will also be softened by blisters.

But it depends on whether you are ** off the paint, the door is much more expensive, the bumper is cheaper, if it is on the corner, you don't need to spray the whole piece, and the other planes are sprayed as a whole, a little bit can't be made up, a little bit can be sprayed, spray is not sprayed.

If the paint of the body cover is only slightly scratched and does not leak out of the metal floor, this situation cannot be rusted. Only when the rubbing wears out all the paint and leaks out of the metal bottom plate, this will be noticed, and it needs to be repaired to prevent rust.

The thickness of automobile paint is different from house to house, generally speaking, thick paint has better protection of the metal layer, unless it undergoes many serious frictions, it is not easy to expose the metal layer, so it is more conducive to rust prevention; Thin lacquer, on the other hand, can expose the metal layer with a single touch, which is naturally more prone to rust.

Generally speaking, the damage to the car paint is divided into several levels:

The lightest is to scrape off only the surface of the varnish, without hurting the colored lacquer, and without revealing the primer, this scar is almost negligible, just throw it away the next time you polish it;

If it is a black car paint, it will basically expose the white primer, if it is a white car paint, it will reveal a black or other color primer, at this time, there is no way to recover through polishing, and it needs to be repainted;

There is also the most serious kind of scratching off the primer, which directly exposes the metallic color, which must be treated accordingly before it can be repaired.

As long as the primer is not removed, it is fine, but if the primer is removed to reveal the metallic color, it will rust, and it is better to touch up the paint.

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.

The car will rust after a long time after the paint is removed.

Iron parts will not rust if the primer does not fall off.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The car will rust after exposing the primer for a long time.

How to deal with the size of the paint dropping:

1. Generally, small scratches can be treated by polishing when there is no damage to the base paint, or even only some small "wear" of the "surface" or some scratch "traces" left on the surface. Basically restore the "original appearance".

2. If after the "collision", you can clearly see the primer or the paint surface that is far from the appearance of the paint (sometimes you can see the metal part), in this case, it is necessary to repair the paint, if the time is too long, it may cause the internal "rust" and expand the "repair range". Therefore, when such a situation occurs, it is recommended to deal with it in time.

3. If there is a "collision" or "scratching" part in the "plastic" parts, such as the front and rear bumpers of some models, if the individual pursues aesthetics, the paint can be touched. However, in cases where the range is small (does not affect the overall appearance) or can be polished, there is no need to touch up the paint, and there is no "rust" (plastic parts) inside.
