What brand of car paint is good to use to protect the bottom of the car

Not at all necessary.

Chassis armor is just a service that fools consumers and doesn't make any sense.

Now all new cars have been treated with anti-rust treatment before leaving the factory, so don't listen to the flickering of car maintenance and beauty shops.

The so-called chassis armor is to spray a layer of plastic on the chassis of your car. If the material is of inferior quality, it is also flammable.

In addition, if the sealing between the plastic and the chassis is not done well, it will be difficult to dissipate the water after penetrating into the chassis, which is more likely to cause the chassis to rust, which is counterproductive.

China's auto maintenance and beauty market is still very unregulated, and there are no relevant standards. Consumers need to be more cautious so that they don't not only spend money unjustly, but also cause harm to their cars.

In addition, the "car paint glaze" on the market is also a long-standing flicker in the car beauty industry, the so-called glaze sealing is to give your car a layer of hard wax and then use a polishing machine to polish deeply, but the surface looks bright, but in fact, the damage to your car paint is very huge.

In order to spend less money, and more importantly, to really protect the vehicle, it is very meaningful to recommend that you know more about automobiles.

The day before yesterday in 4s, a car owner to do car maintenance, after-sales personnel to give advice after **1980, the owner felt expensive, but the after-sales service staff said that the suggestion is better, and finally the owner signed. The whole is a big wrong, if you have a little common sense, you can get it for 200 yuan, but in front of 4S people, it's not easy to remind you.

Protecting the bottom of the car is not with car paint, it needs chassis armor, it has the effect of anti-corrosion, wear-resistant, and noise reduction, and it is not very expensive (as long as you are not a big car!!) ）

Apply wax regularly, avoid collisions with hard objects, avoid direct sunlight, etc.

Waxing can better protect the car paint, and apply a layer of grease to the car paint, which can reduce scratches and reduce the fall of dust. If you want to save costs, Lao Shen recommends buying your own special wax for cars and then waxing it yourself.

Frequent car washing is very important to protect the car paint, especially when it has just rained and there is a lot of dust, but special attention should be paid to the method of car washing, not too hard cloth, and the car should be fully wet before wiping the car.

Avoid collisions with hard objects. When driving, you should pay attention to the friction of hard objects on your body, such as keys, on the vehicle, which will hurt the car paint very much, so pay attention to it.

Careful polishing, although car polishing can make the vehicle very bright, but the damage to the primer is not small, generally speaking, the vehicle's lifetime polishing can not be more than 5 times.

Avoid prolonged direct sunlight, which will cause the paint to deteriorate and lose its luster, so it is better to stop the vehicle in a cool place or in the garage.

The following is the role of automobile primer: 1. Closure: Some walls are more alkaline, and alkaline flowers are produced after being soaked in moisture and water, the scientific name is "pan alkali", which causes the formation of crater-like protrusions on the surface of the paint film, and forms a layer of alkali cream on the surface of the paint film when it is not serious, and finally destroys the paint film.

Latex paint primers can act as a sealant to alleviate this situation. However, if the walls of your house are dry and the floors are higher, it may not be a problem if you don't use it, but it is recommended that you use insurance; 2. Adhesion: The emulsion content in the primer is high and the adhesion is strong.

It can improve the adhesion between the latex paint film and the wall; 3. Filling: If your wall is not alkaline and relatively flat, you can quietly regret not using primer, of course, it is better to use a layer of sealing primer before painting topcoat, which can not only save decoration costs, but also have the advantages of painting primer in the long run and decorative effect. At the same time, the good adhesion of the primer makes the wall surface smoother, making the topcoat easier to apply and reducing the amount of topcoat used.

In this way, the wall not only avoids paint sickness, but also helps to maintain the painting effect for a longer time.

Automotive primer is the first paint applied directly to the surface of the workpiece after surface treatment, and is the basis for the entire coating. The primer is required to have good adhesion to the substrate, good compatibility with the upper middle coat or topcoat, and should also have good corrosion resistance, rust resistance, oil resistance, chemical resistance and water resistance. Of course, the paint film formed by the automobile primer should also have qualified mechanical properties such as hardness, gloss, flexibility, and stone chip resistance.

The characteristics of automotive primer are that the surface treatment should have good adhesion to the surface of the workpiece, and the primer film formed should have excellent mechanical strength.

The primer itself must be an anti-corrosion agent, the primer coating must have excellent corrosion resistance, water resistance and chemical resistance, and the intermediate coating or topcoat coating is well matched, can adapt to the assembly line production characteristics of the automobile coating process, and has good construction performance, and the automotive primer is mainly divided into solvent-based primer and electrophoresis primer. The primer for passenger cars is mainly solvent-based primer, mainly epoxy ester epoxy polyamide and epoxy polyurethane coating, which requires salt resistance of more than 500h. Water-based primers are mainly cathodic electrophoretic coatings, which are mainly used for the coating of automobiles and miniature lamp bodies.

The function of automobile primer: (1) filling function: fill the pores inside the steel plate, which is convenient for surface coating.

2) Supporting topcoat: ensure that the topcoat can be closely adsorbed with the surface of the car. (3) Provide fullness:

Because there is a lot of powder in the primer, the thickness of the paint can be provided. (4) Reduce costs and save energy: because the primer is general.

Spraying primer primer primer is the basis of the whole coating, and the adhesion and anti-corrosion of automobile coating and metal mainly depend on it. The primer should be a coating with strong anti-rust performance, strong adhesion to the substrate, good adhesion to the middle coat or topcoat, and good mechanical properties of the coating film.

To protect the car paint, you can go to the car beauty shop to seal the glaze! It can prevent the wind and sand from damaging the paint surface, but it cannot guarantee man-made damage, and there is a car cover, which can completely cover the car to prevent children from scratching the paint surface by playing with the brush, unless others deliberately destroy it, then there is no way. If there are scratches on the paint surface of the car, as long as the paint is not damaged, it can be polished.

If the primer is injured, you can only touch up the paint and spray paint.

Automobile sealing glaze, less polishing and more waxing is the best way to protect the paint surface.

The right thing to do for paint protection:

1. Try to park your car in the garage, and do not have strong sun exposure when parking to reduce rain.

2. Do not dry wipe the car, the small sand on it may wear the paint surface, be sure to wash it with water.

3. When the car is just bought, it should be sealed with glaze once, and then less polishing and more waxing.

4. Don't park indiscriminately when you go out to park, if you get in the way, you will be recruited to draw paint.

In the traditional car maintenance method, in order to maintain the brightness of the body, the owner can often only choose frequent car washing and waxing, but this practice has no hardness and sticky dust, easy to scratch the paint, accelerate oxidation and corrosion, but make the car lose color for a long time. At the same time, waxing can not effectively resist ultraviolet rays, it is difficult to really protect the paint surface, and the method of polishing to remove small scratches on the body will cause the paint to become thinner and thinner, and finally have to be repainted, resulting in a serious depreciation of the car. Paint transparent protective film is the ultimate solution for new car maintenance and paint beauty.

Many car owners can choose film maintenance. Because of its convenience, durability and practicality, it is quite popular with the majority of car owners. So far, there are many domestic protective film brands, but most of the warranty is only 7 years at most, recently saw a new imported film brand warranty reached 10 years, it is recommended to understand about the CARPEL automotive paint protection film, is an imported film from the United States, after strict testing applied to the protection of automotive paint, with traditional film can not be matched with wear resistance and scratch temperature repair performance, its own no oxidation, no yellowing, no degumming, and will not produce secondary pollution to the car paint, has emerged in the industry, Favored by many high-end car owners.

However, compared with other maintenance methods, the protective film is definitely more expensive, and the specific sticker or not, you still have to measure it yourself.

First, the role of the primer.

Primer is the lacquer used for the primer, which is generally applied directly to the surface of the object or applied to the surface of putty. Its function is to prevent oxidation and corrosion of the metal surface, and to enhance the adhesion between the metal surface and the putty (or intermediate coat, topcoat), putty and topcoat. The right primer is a prerequisite for a durable and aesthetically pleasing topcoat.

If the primer is not good, the appearance of the topcoat will be affected and even cracks or peeling will appear.

The function of automobile primer is to prevent corrosion caused by oxidation of the metal surface, and it can also enhance the adhesion between the metal surface and the intermediate coating, topcoat, putty, etc. Primer, also known as primer paint, can generally be applied directly to the surface of the object or putty.

Automobile primer is the first coating directly applied to the surface of the surface treatment of the parts themselves, which is the beginning of the whole coating. The design requires that the primer and the substrate should have good adhesion, have good matching with the middle coat or topcoat above, and must also have good corrosion resistance, rust resistance, oil resistance, chemical resistance and water resistance.

What is the role of car primer? I think car primers generally have anti-rust functions.

The function of the automobile primer is: it has good matching properties with the middle coat or topcoat above, and must also have good corrosion resistance, rust resistance, oil resistance, chemical resistance and water resistance.

Primer requirements.

1. It should have good adhesion to the surface of the workpiece after surface treatment, and the primer film formed should have excellent mechanical strength.

2. The primer itself must be a chemical inhibitor of corrosion, and the primer coating must have excellent corrosion resistance, water resistance (moisture resistance) and chemical resistance.

3. Good matching with intermediate coating or topcoat coating.

4. It can adapt to the characteristics of a large number of flow production of automobile coating and answering process, and the primer should have good construction performance. In order to have the above characteristics, the main paint bases used in the manufacture of automotive primers are various epoxy resins, phenolic resins, alkyd resins and some high-quality water-soluble resins. Alkyd resin has been eliminated due to poor moisture resistance and easy bubbles.

Automotive primers are filled with high-quality anti-rust pigments.

One is to prevent oxidation and corrosion of the metal surface, and the other is to increase the adhesion between putty and topcoat.

The primer is in direct contact with the metal, which protects the metal and prevents the metal from rusting, and can play a role in priming the above layer of paint.

The car primer plays a role in protecting the metal, preventing the metal from rusting, etc., and can play a role in the primer for the above layer of paint.

The primer used in car painting is baking paint.

Baking paint is divided into two categories, one type of low-temperature baking paint curing temperature of 140 °C-180 °C, the other type is called high-temperature baking paint, its curing temperature is 280 °C-400 °C. High-temperature baking paint, the full name of polytetrafluoroetylene in English, referred to as Teflon, PTFE, F4, etc. Teflon high-performance special coating is a fluorine coating with polytetrafluoroethylene as the matrix resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon, etc. (all are the transliteration of Teflon).

The primer is primarily rust-resistant while providing a stable and firm base for the topcoat.

Protect the chassis, are you spraying ground armor.

1.Waxing forms a wax film on the surface of the paint to inhibit the oxidation of the paint by external harmful components. It is UV resistant, has a high brightness, and is the cheapest.

Generally, after buying car wax in the car beauty shop, the beauty shop will be responsible for free waxing, the disadvantage is that the protection time is very short, generally only 4 to 5 days at a time, and it will lose its effect when washing the car, the main disadvantage is that there is silicon in the wax, which has an oxidizing effect on the car paint. It is recommended that new cars try not to apply sandwax. The main function of sand wax is to remove fine scratches and dirt from the surface of the car paint.

2.Sealing glaze can increase the strength of the car paint, prevent small scratches caused by wind and sand on the car body, and resist high temperature and ultraviolet rays. The retention time is relatively long, which can reach 6 to 8 months, which has a substantial protective effect on the paint surface and can make the paint feel delicate and soft, but the biggest disadvantage is that the glaze is a compound extracted from petroleum, which is very harmful to the car paint.

The high-frequency polishing during glazing is a kind of damage to the automotive paint, and in addition, the protection time is shorter than the coating time.

3.Coating beauty is the highest measure of paint protection, which can avoid oxidation and achieve multiple effects of brightening, anti-acid and alkali, anti-oxidation and anti-ultraviolet lamp. Since the material of the membrane itself is an inorganic substance, there is no damage to the car paint.

Generally, when coating the car, the paint leather that has become discolored and brittle due to aging and the oxide layer formed by long-term corrosion will be removed at the same time. It can increase the hardness of the paint surface and avoid small scratches and apertures. It also has the longest retention time, about more than two years.

The coating effect is the best, and the coated products should occupy the market for waxing and glazing, and now the good coating effect is good, you can try it.
