What to do if there are scratches on the engine cover of your car

Shallow scratches can be sanded with sandpaper to remove impurities and rust, then through paint surface reduction, waxing, and finally polishing with polishing agent until the paint film is smooth and bright.

Medium and deep scratches cannot be repaired by grinding methods, and the concavity of a small area is not more than 5mm, which can be filled with putty.

Leveling, and then touch-up paint treatment. If the metal is exposed at the scratch, the surface coating rust and welding slag should be cleaned first, sanded and smoothed, and then applied an oxidation neutralizer with anti-rust effect, sprayed with primer, and repeated the process of painting, drying and sanding.

The more serious deformation should be treated by sheet metal. If you use a touch-up pen, there may be obvious color difference in the vision, but the difference can be more prominent. It can be handled in the first way above.

Car paint maintenance tips.

1. Daily maintenance.

When parking, try to park indoors and do not often expose yourself outdoors to the sun, wind and rain. If there is bird droppings, gums on the paint.

etc., dispose of it immediately, do not dry wipe when wiping the car, and gently wipe the paint with a wet towel. When you go out to park, don't just park your car. If you get in the way, you will hire someone to draw paint.

2. Monthly maintenance.

Apply wax once a month on a regular basis, and as for the effect, the first thing is waterproof and acid-proof rain.

Reduces the amount of water beads adhered to the body. The second is to prevent sunburn from high temperatures.

Coated with wax to form a thin film can reflect part of the light, effectively avoiding the aging of car paint.

Scratches on the car engine can be solved in this way. This is generally not available. 6 tips for scratch inspection and repair of body aging 1. No matter what kind of car there will be large or small scars.

If it's a scar that isn't very noticeable, it's a smart idea to leave it alone. 2. The best way to repair the abrasion of the car paint is to fill the scar part with the same coating agent as the body. The coating can be applied several times, and the more times it is, the cleaner it is.

But pay attention to the uniform handling of the entire body. 3. If the body is only a very shallow scratch surface paint, treat it with a mixture, and the wiping method is straight line wiping. Once the scars have disappeared, wipe with a finer mixture before waxing.

4. For deep scars, if you can't see the metal surface, it won't rust, and you can apply retouching paint. Use the tip of the pen to point it little by little, then wait for the paint to dry completely. 5. Very deep but slender scars, repaired with colored putty.

Use sandpaper on the scars, do not enlarge the scar surface, and remove the dirt. The putty is carefully applied so that it completely enters the interior. Finally, apply the mixture and wax.

6. Dentage treatment is the most troublesome work in body maintenance, the important thing is to lay a good foundation, if this step is not done well, no matter how good the painting is, the effect is not good. When spraying paint, cover the surroundings with newspaper so that the paint does not spread around.

This is not easy to judge, if it has just appeared, you can call up the surrounding monitoring. Scratches on the hood may have been hit by stones at high speeds, or they could have been scratched by some tree branches. There are a lot of scratches on the surface of the car paint, and these scratches are basically on the varnish layer, which is generally easier to leave scratches when washing the car.

The body paint is divided into four layers, from the inside to the outside, which are the electrophoresis layer, the middle coat, the color paint layer, and the clear coat layer. After the body is assembled, the entire body is soaked in the electric pool so that an electrophoretic layer can be formed on the surface of the body. The function of the electrophoretic layer is to prevent rust.

Once the electrophoretic layer is formed, the robot sprays the middle coat, which also acts as a rust prevention and improves the bonding ability to the next coat.

The third layer is the color paint layer, and this layer of paint is the body of various colors that we can usually see. The role of the color paint layer is to make the body beautiful. The fourth layer of paint is the varnish layer, which is on the outermost part and plays the role of protecting the color paint layer, and can also improve the gloss of the car paint.

The small scratches that are usually left are on the varnish layer, and these scratches can be removed by polishing. However, it is not recommended that the owner polish frequently, which will reduce the thickness of the paint layer, and the gloss of the body paint will decrease over time.

If the scratch hurts the paint layer, it needs to be repaired by spray painting. If the scratches are very small, it is not recommended for the owner to repair them with painting. Because the quality of the paint sprayed after the car is not as good as the paint sprayed on the production line***.

Car scratch treatment

First of all, we can use some daily necessities to deal with scratches on the body, such as toothpaste. We can apply toothpaste to a wet towel (note that the wet towel should not have too much moisture, be sure to wring it out), and then wipe the scratch area repeatedly, because toothpaste, like car wax, contains very fine particles, and when you slowly wipe the scratch, the slight scratch will be polished clean.

After repeated wiping, we can dry the vehicle. And the nail polish that our girlfriends or wives often use.

It can also be used to repair scratches. We can choose a nail polish that is close to the color of the body, and then apply it to the scratches on the body, and after the application is done, we must also remember to dry it.

In addition, car wax is also a very good choice. The principle of treating scratches with toothpaste is exactly the same as that of treating scratches with car wax, and the same is the use of small particles to grind minor scratches clean.

At the same time, if the deformation of the body is not severe, we can also repair the deformation ourselves, for example, using a depression repairer. When we use a dent repairer, we need to first use the spacer.

Apply hot melt adhesive on top.

Then glue the spacer to the hollow, then insert the glove into the screw of the spacer and rotate the nut.

Slowly pull the depression back.

If the dent repair is finished, then we use a scraper to remove the gasket, taking care not to scratch the car body when taking it. If the depression is too large, we can also repeat it several times until the depression is pulled back.

The scratches on the hood of your car don't look like they're intentional, or like someone made them with a hard object. It's likely that something quite heavy was placed on your engine trap cover, and it moved sideways when it was removed, so it left a trace. If it's a scratch on a key, it's impossible for the two marks to be so parallel.

It's also possible that someone has swept the dirt off your car with a broom. It's also possible that when you are wiping the car, there are stones and sand grains on the rag. In short, it doesn't look like someone is sabotaging.

If there is only such a piece, then it is basically certain that it is artificial. There is a dash cam that can be turned on to take a look, or park near to see if there is any monitoring.

Such scratches should not be early man-made scratches, it is possible that you went to the automatic car washing machine and were scraped by the brush, and the brush was stained with fine sand particles when the scratch was not visible when washing the car.

Under normal circumstances, whether you go to the car wash or wipe the car yourself, there will be no such obvious scratches, it is obvious that your car has been artificially scratched, in this case you can call the police. Find the person responsible by calling up the surrounding surveillance.

If you don't care if you're generous, then it doesn't matter, this kind of scar only affects a little beauty, and will not have any impact on the use of the vehicle.

According to the **, it should be man-made, if it is hung on a branch or other things, the scratch should be horizontal rather than vertical.

No, it feels more like a mark caused by putting something on top and then dragging it off when you take it down.

Alarm can be called. I can find the culprit who scratches the car hood scratches. Give you justice.

Because you don't usually pay much attention to the top cover, you may sometimes paint on the branches on the country road, and you don't pay much attention to it.

You can spray it locally, my husband is a car dealer, the last time the car was scraped, he called ** to a colleague, and the colleague said that it can be sprayed locally.

If there are scratches on the inside of the engine block and scratches on the cylinder wall, this is a problem with the cylinder pulling. The engine had to be overhauled. The piston and steel sleeve need to be replaced.

If the spring disturbance involves the wear of the crankshaft and connecting rod, it is necessary to replace the crankshaft and connecting rod, which is a big project, and it is recommended to go to a 4S shop or a large repair shop for maintenance.
