How to deal with paint scratches? How to repair a slight scratch on the paint surface of a car?

Minor scratches, such as sunburst lines, only damage the surface of the paint, are less damaging to the paint surface and are easier to repair, and can be solved by waxing. You can choose scratch wax first, use a waxing sponge to grind the scratches, remember to rub clockwise or counterclockwise in one direction. Then use brightening wax, and the paint surface after waxing looks brighter, which basically solves the problem.

There is also a more cost-effective method of repairing with toothpaste, gently applying it to the shallow scratches, and then rubbing it counterclockwise with a soft cotton cloth to not only reduce the scratches, but also avoid the erosion of the air on the paint wounds.

Deep scratches. For deep scratches or even leakage of primer, many car owners will try to polish, and it is generally difficult to solve the problem in this case. The scratches are not big, and there is no need to repaint, so it is recommended that you can use a touch-up pen to touch up the paint.

This general auto supply store sells it, usually about thirty or forty yuan. Before using the touch-up pen, shake the paint inside the touch-up pen evenly, apply the scratches like nail polish, and wait for the touch-up pen to dry, and then apply some brightening wax.

Scratches with a large area of leaking primer.

For scratches or scratches that have leaked primer, the first thing to do is to prevent rust. For scratches that leak primer, you can solve them with the above methods. Generally, the bumpers, mirrors and wheel arches of some cars are made of engineering plastic and will not rust.

If the owner is not demanding, you can do without touch-ups. Other parts need to be painted, if the damage area is large, you need to repaint, if the area is not large, you can use a paint brush or self-spray paint to solve the problem.

Scratches from depression deformation.

This kind of damage is generally difficult to repair perfectly, and it needs to be dealt with in a 4S shop or a quick repair shop, which requires sheet metal treatment and then repainting.

In addition to this, it is important to note that:

1. When exposed to the sun and rain, small scratches may also damage the body paint if they are not repaired in time, because the rain will penetrate into it through these "wounds" and accelerate rusting.

2. If the car is often parked under the tree, clean up the fallen leaves in time. There is also resin in the paint composition, and some trees drip down like resin, and if it sticks to the paint and is not cleaned up in time, it will remain on the paint like glue.

3. There is also bird droppings, which are more powerful for corrosive paint. If the car is parked under the canopy, the canopy contains galvanized things, and if it is parked for a long time in rainy days, the acidic things will seep into the car with the rain dripping. Even if your car is waxed regularly, it will corrode the paintwork.

How to deal with paint scratches? What are the treatment methods for paint scratches?

Scratches are generally divided into three kinds, first of all, we must distinguish the depth of the scratches, first observe the scratched paint surface, whether there are any traces of depression around the scratches, and then you can touch the scratches with your hands, and the feeling is convex, which is the lightest scratches.

This situation is the easiest to deal with, first clean the place that needs to be treated with the car, then wipe it with a clean car towel dipped in a little toothpaste, slowly wipe off the scratches, expose the original car paint, and then wipe it clean with a car towel. If we feel slightly concave to the touch, we can see shallow scratches on the surface of the paint. Most of these scratches are off-white or colorless, this kind of scratches have hurt our car paint, or hurt the paint on the surface of our car paint, although it is not very serious, even if it is not treated, it will not have more damage to our car, but it will affect the beauty of the car, and no matter how inconspicuous the car is, even others can not see it at all, but the owner can always see the scratch at a glance, and the heart will be a little uncomfortable.

If you go to the car beauty shop for this kind of scratch, most of them will suggest that we polish it, the so-called polishing is to throw away the outermost layer of our car paint with a polishing machine, revealing the car paint that has not been damaged inside, and the polished car will be as bright as new as new, but the car paint is as bright as new, but the car paint is a certain thickness, and the paint is thinner every time it is polished, and the paint is more likely to be scratched than the original, if it is not for the whole vehicle to have scratches, the area of the scratches is relatively large, it is not recommended to polish. This kind of scratch can also be dealt with by ourselves, with a clean car towel dipped in a little car-specific grinding coarse wax, and then use a towel to slowly paint circles on the surface of the car paint, pay attention to try not to rub a good car paint, see that the scratches are no longer obvious or have disappeared, and then use a towel to wipe the paint surface. Coarse wax is available online, and without coarse wax you can replace it with a scrub cleanser or body wash.

If the scratches are very deep, you can already see the primer that is different from the color of the body, and even the iron plate inside, which is the most serious scratch! We need to deal with this kind of scratch first with the above method, try to reduce the scar of the car paint, and then repair it with a touch-up pen of the same color as the car paint, which can prevent rust on the scratch part and make the car look more beautiful.

1.Shallow scratch treatment: Use a polishing wheel with polishing brightener to remove impurities, oxide layers and fine scratches attached to the car paint.

2.Deep scratch treatment: Observe whether the metal surface is exposed, if not, clean the damaged part first, and fill it with repair paint. In order to enhance the adhesion effect, you can first sand it with high-mesh sandpaper.

3.Touch-up: If the metal is exposed at the smash site, apply an oxidation neutralizer with anti-rust effect before painting, and then spray the primer after the neutralizer is completely dry, and repeat the process of painting, drying and grinding.

4.Emergency measures: If you don't have time to go to the maintenance station to repair the car temporarily, you can apply a layer of nail polish to the scratched part to prevent oxidation and rust. Then go to a regular local repair shop.

5.Touch-ups over large areas: Foam primer is mandatory, and air-dried primer can be used for quick-fix scratches. The air-drying primer dries quickly, which can ensure the time of quick repair.

6.Pre-maintenance: New cars should be coated with a layer of mirror glaze on the body. Mirror glaze is made of polymer as the main component, which directly acts on the surface of the paint, which can greatly improve the hardness of the paint surface.

7.Avoid using car covers: once it is windy and rainy, blowing on the car clothing, the inner layer will repeatedly whip the car paint, and it is easy to scratch many small scratches on the car body, these scratches are all over the car, cleaning or waxing can not be completely removed, and it will cause the paint to be black for a long time.

There are the following remedies for scraped paint:

1. Lacquer pen repair method, paint the scratch with a similar color paint pen, this method is relatively simple, the process is not complicated, the firmness is poor, it may be washed off several times, only for short-term appearance maintenance first aid.

2. Painting method, using the traditional method to repair deep scratches, rust removal and filler, dry and polish with water sandpaper, repeat many times until leveling and then repair paint. This method has a large damage area to the original car, a long repair time, a certain color difference, and a slightly worse effect.

3. Computer paint mixing method, computer paint mixing method adopts a new process, the repair area is small, after special solvent treatment, the new and old paint surface are integrated, firmly attached, and can be repaired immediately, as long as the repair process is appropriate, the repair effect is good.

How to repair a slight scratch on the car paint, this should be divided into situations, if the scratch is not very deep, and the sheet metal parts inside are not exposed, at this time, you only need to wax it, if the scratches are very deep, and the sheet metal parts inside have leaked out, this time it is necessary to repair the paint, because the scratches are deep, if the rain is soaked for a long time, it is easy to cause the paint around the scratches to enter the water and blister, or the sheet metal parts are rusty, so the scratches are deep, and they should be treated in time.

The repair methods for minor scratches on the paint surface of the car are: 1. Apply toothpaste: apply the toothpaste to the scratches, and then wipe them back and forth, which can effectively remove the scratches and prevent rust; 2. Waxing:

Minor scratches can be removed with ordinary maintenance wax, and sand wax should be used when the scratches are heavy; 3. Paint repair pen: you can use the paint pen to make up the color of the scratches, if the scratches are deep, the scratches should be repaired first, and then the paint repair work should be carried out, the steps are waxing, polishing, wiping, and the wax should not be put too much when waxing, which can cover the damaged area of the paint surface; 4. Erase with an eraser: Some marks are very shallow and can be erased with an eraser.

Minor scratches on the paint surface can be ground with toothpaste or polishing wax, and then fine waxing.

【Pacific Automobile Network】The treatment method of car scratch paint, for relatively shallow scratches, you can use scratch car wax polishing; Moderate scratches can be repaired with touch-up pens; If the scratch has already exposed the primer, it is necessary to do a partial touch-up. If the scratches are not repaired for a long time, the base part is easy to rust, and it will gradually affect the good paint surface around it.

During the daily use of the vehicle, it is inevitable that some hard objects will scratch the paint and leave traces, such as the zipper on the backpack of passers-by or the small stones that burst while driving. Often this slight scratch is the most common on the body, but it does not affect the beauty of the body, and it can generally be ignored in this case. For minor injuries, in addition to passive acceptance, it can also be prevented in advance, waxing once a month or two or putting anti-wear patches on places that are often prone to wear and tear can avoid minor scratches to a certain extent.

For those vehicles that have appeared shallow scratches, you can use scratch removal car wax polishing, and generally shallow scratches can be removed. If it still doesn't work, you can also use the polishing method for quick processing. The polishing wheel is used with the polishing brightener to remove the oxide layer attached to the surface of the car, flatten the fine scratches, and at the same time, the agent penetrates into the car paint to reduce the change, not only the shallow scratches are removed, but the paint surface is also renovated.

In addition, if the damage to the paint is not very obvious or you don't want to use a touch-up pen, there is actually another way to solve the sticker. It's also good to cover up scratches with your favorite stickers, and it's better to look at than with a touch-up pen. (Photo by photo:.)

Minor damage: you can use a touch-up paint pen Most of the damage in this case is that you can see the scratches on the paint surface very clearly or the traces left by the friction of objects on the paint surface. Of course, you must buy a touch-up pen that matches the color of your car paint, but you don't have to worry about buying the wrong color, you just need to know what color to add to the official name of your car paint, and then buy a touch-up pen of the corresponding color.

However, there is a disadvantage of using a touch-up paint pen that the place of application will be very uneven, because after all, it is not covered by spraying, so after using the touch-up pen, the paint will be potholes after solidification, although it can't be seen fiercely, but you can still see it if you look closely. In addition, if the damage to your car paint is not very obvious or you don't want to use a touch-up pen, there is actually another way to solve it - stickers. It's also good to cover up scratches with your own stickers that you like to want, and it's better to look at than with a touch-up pen.

Moderate damage: go to a quick repair shop for repair If you encounter this kind of damage, it is estimated that your car is in close contact with the flower bed or the pillar on the ground, and the paint has clearly peeled off to reveal the primer (usually the primer is white). Generally, the paint is so bad that the primer must be treated as soon as possible to avoid the steel plate at the damaged place being corroded by rain or other objects.

(1) Paint pen repair method. Applying a paint pen of a similar color to the scratch is a paint pen repair method. (2) Spraying method.

Scratches are repaired using traditional touch-up paint methods. The disadvantage is that the damage area of the original paint is too large, the repair time is too large, and the effect is difficult to be satisfactory.

1. Basic methods of car scratch repair.

1) Lacquer pen repair method.

Applying a paint pen of a similar color to the scratch is a paint pen repair method.

This method is simple, but the adhesion of the repair paint is not enough, and it is easy to peel off and difficult to last.

(2) Spraying method. Scratches are repaired using traditional touch-up paint methods. The disadvantage is that the damage area of the original paint is too large, the repair time is too large, and the effect is difficult to be satisfactory.

3) Computer paint mixing spraying method. Combined with the deep scratch repair technology of computer paint mixing and new process methods, this is a fast technical repair, but it requires accurate color matching, the repair area is reduced as much as possible, and then after special solvent treatment, the new and old topcoats can be better integrated to achieve optimal adhesion.

2. If the mirror treatment of automobile topcoat is polished with sandpaper and "coarse wax", it is difficult to make the car paint achieve the mirror effect. Therefore, automotive paint care materials must be used in the treatment of automotive paint mirrors. At present, putty and polishing agent are generally used, and the best material for mirror effect is polishing agent.

In fact, polishing is also an abrasive, which is an abrasive that contains a friction material with finer particles. The size of the material particles or efficacy of the polish is divided into three types: micro polishing, medium polishing and deep polishing. Micro-polishing is used to remove very slight paint damage, generally refers to the environmental pollution and acid erosion (guano, fallen leaves, etc.) that have just occurred (within a few days), but this kind of minor damage can currently be replaced by wax containing polishing agent; Medium and deep casting are mainly used to deal with different degrees of hair scratches.

In addition, the effect of medium polishing is better for transparent paint, while deep polishing is faster for ordinary paint.

Generally speaking, polishes and reducing agents are the same class of materials in terms of the friction materials they contain, but the main difference between the two is that the reducing agent contains a polishing material (polish or wax), while a polishing agent does not contain a polishing material. It is important to have a "mirror effect" on automotive paints with non-glazing materials.

The main ways to improve the gloss of automobile paint to achieve the "mirror effect" and polish are:

1) By grinding and rubbing the material, the fine scratches are hard to remove.

2) Relying on the efficacy of wax, after polishing to a certain extent, rely on the luster of wax to make up for the defects of polishing.

3) Relying on chemical reaction, that is, relying on the adjustment of the speed of the polishing machine to produce the chemical reaction of the polishing agent.

The first two methods are more used by beginners.

The main reason is that beginners do not have enough understanding of the speed of the polishing machine, the material of the polishing head (wool material, blended material, sponge material and cotton material, etc.), the structure of the lacquer and the relationship between the efficacy of the polishing agent, and lack of experience, so the requirements for polishing are not high.
