How to deal with the car paint that is not smooth and not bright?

Polishing and waxing can be carried out, polishing is a method of removing scratches and rough uneven parts on the surface of the car paint through grinding wax and polishing machine, and polishing can grind off the aging paint film of the paint surface, so that the new paint film is produced and restored to brightness. After polishing, waxing or glazing can achieve better results.

Polishing process: 1. Wash the car and remove iron powder and impurities.

2. Inspect all paint surfaces to confirm the degree of defects such as scratches, oxide layers, acid rain spots, dust spots, and orange peels on the paint surface.

3. Cover the area that needs to be painted.

4. Grinding, grinding is the use of abrasives to solve the deep problems that affect the appearance of the paint surface, such as oxide layer, streaks, pollution, and fading.

5. Polishing, polishing is a process after grinding, which is different from the role of grinding. Grinding is to flatten the paint surface to remove deep pollution such as stripes and oxide layers; Polishing is to further smooth the paint surface after grinding, remove the residual stripes of grinding, and the moisturizing ingredients in the polishing agent penetrate deep into the paint surface to make the paint surface show a soft own luster. The polish can also be used alone to remove minor oxidation and dirt.

Waxing process: 1. Apply car wax.

1) Use a waxing sponge to dip an appropriate amount of wax into the wax, and evenly apply the wax in a small circle and rotation; The size of the circle is subject to the paint surface without omission in the circle, and each circle covers the previous circle 1 3, and the circle trajectory is in a straight line along the front and rear of the body.

2) Waxing sequence of the whole car: divide the paint surface into several parts, and grind the right half of the body in the order of right front hood - left front hood - right front fender - right front door - right rear fender - trunk lid, and grind the left half of the body in reverse order. Until all lacquer surfaces are waxed without missing a beat.

3) Evenly coat a thin layer of car wax on all paint surfaces, subject to the paint surface obviously covered with a layer of car wax, and the front and rear plastic bumpers of the painted should also be coated with wax.

Car waxing,As a traditional project of car beauty, the role of waxing is first of all waterproof, anti-acid rain, due to the protection of car wax, the amount of water droplets attached to the body will be reduced, the effect is very obvious, can reach 50% to 90%.

The second is to prevent high temperature and ultraviolet rays, the weather is getting hotter and hotter, the car is easy to drive or store outside all the year round due to the aging and fading of the car paint, and the film formed by waxing can reflect part of the light, effectively avoiding the aging of the car paint; The second is that car wax can be anti-static, and of course, it is also dust-proof.

The friction between the car and the air generates static electricity when driving, and the car wax can effectively isolate the friction between the car body and the air and dust. Less electrostatic cars naturally have less dust adsorption, and car wax can also play a role in glazing, making the car look newer and better.

Car paint has no gloss Reason:

The gloss of automotive paint is related to the smoothness of its surface, and any loss of light is due to the unevenness of the surface, which makes the light excessively diffuse and loses the clarity of the reflected image.

1. Gloss is the prelude to the gradual damage of the paint film when the coating film is exposed to the atmosphere, and the surface produces a chalk layer (white or light paint) and bright copper (dark blue or maroon paint). The onset of chalking, although not visible to the naked eye, is enough to make the surface uneven and tarnished. If you look closely with a magnifying glass, you can identify the condition of the chalking.

2. The damp prickly heat particles begin to be very fine, and it is difficult to detect with the naked eye, and the first step in identification is usually considered to be tarnishing. When examined with a magnifying glass, a very large number of very fine bubbles can be seen.

3. Early loss of light is related to the poor weather resistance of the selected coatings, or the use of indoor coatings as automotive repair topcoats.

4. When using two-component automotive repair topcoats, the amount of curing agent is insufficient or the curing agent supporting the manufacturer is not used or the dilute containing a large amount of water, alcohol or acid is used.

The paint of the repair is definitely different from the paint of the original car, mainly in the following aspects:

1. The spray gun used when spraying the original car paint is multi-nozzle, so it is more uniform. The 4S shop is sprayed manually, and the spray guns with a single nozzle are used, and the effect is definitely not as good as the original car paint;

2. The temperature of the paint room is relatively high, and the hardness of the paint is relatively good. The temperature of the paint room in the 4S shop is not up to the temperature of the original paint;

3. Now most of the paint mixing in the 4S shop is painted by the paint mixer to match the paint in proportion, so it is normal to have color difference. The new paint must be brighter than the old paint, if there is no obvious color difference, that's it, generally 90% is OK.

Hope it helps.

2. After washing the car, you can start waxing.

In a nutshell, the structure of a car paint is primer, middle coat, topcoat and clear coat from the inside to the outside.

The primer is used to form a solid, stable and flat paint surface on the metal surface, which lays a good foundation for the spraying of the topcoat and also has the effect of rust prevention.

The middle coat is between the primer and the top coat, generally appears on the middle and high-end cars, in addition to its role with the upper and lower coatings have good adhesion and adhesion, but also has the ability to fill and sand, so as to obtain a smooth surface. A topcoat is a coating that is used to express the color of the body on the basis of the primer.

Varnish is a colorless, transparent, glossy coating, the top layer of car paint, which forms a thin film on the surface of the topcoat and is specially designed to protect the topcoat while also bringing shine to the topcoat surface.

The maintenance of car paint can be divided into four ways: waxing, glazing, coating, and crystal plating. Waxing.

After waxing, a thin film will be formed on the surface of the car to delay the aging and oxidation of the paint, and the film can also resist the scratches of some fine hard objects on the paint surface. Glaze sealing: The glaze is pressed into the paint with a professional tool, and the glaze molecules penetrate into the gaps on the surface of the paint, thus forming a protective film that can reflect light.

Compared with waxing, the sealing glaze has a stronger ability to resist scratches. Whiteskin Beauty is a product of nanoskin, a car expert from the United States. Throw·; Clean·; Nourishment·; The five-step method of "protection" deeply solves the problem of white car maintenance. By reacting with metal ions, the paint surface is fully soaked and moistened in the cleaning process to remove the metal dust ions on the paint, glass and wheels, and restore the original color of the white car.

Coating: The coating has a stronger function in anti-oxidation, wear resistance, corrosion resistance, etc., and lasts for the longest, so the return cost is higher than that of waxing and sealing glaze, and the market price ranges from 1000 to 3000, and the effect can be maintained for at least half a year. Crystal plating:

The reagent penetrates into the paint hole to form a layer of crystals to improve the hardness and gloss of the paint, and has strong corrosion resistance and scratch resistance.

Hello, if the black paint is not bright, it is recommended to make a whole car crystal plating effect for the car, and it will also protect the paint surface.

Hello, for the black paint is not bright, you can go to the repair shop or beauty shop to do a polishing, this can effectively improve the brightness of the paint, the general cost is about 200!
