Polishing cars: description, see, materials and equipment

September 14, 2019

Polishing cars has a variety of purposes - there are many types and methods of this procedure and each of them helps to solve a problem. Among the most common tasks of this procedure are called the following:

  • removal of scratches and abrasions - with the help of abrasive materials a thin layer of paint is removed, due to which the microrelief is leveled and the surface becomes smooth;
  • application of a protective layer on a paint and varnish covering of the car - protective types of polishes form an elastic film, which helps to neutralize the influence of external factors;
  • providing paint depth and glossy gloss. Compare the appearance of an old car before and after applying the polish - you will see, that it looks no worse than a new car. This procedure is performed before the sale of the car - owners often successfully use this technique.

After painting, even the most high-tech, it is difficult to avoid some obvious defects

As in any other type of surface treatment, there are pros and cons. The positive aspects include:

  • elimination of small mechanical defects;
  • glossy shine and color depth;
  • protection against moisture, corrosion, burnout, dirt, etc.. P.

The disadvantages include the gradual thinning of the paint layer, which leads, eventually, to the need to repaint the machine. In addition, the polishing method eliminates defects, the depth of which does not exceed the thickness of the paint - to get rid of deep scratches, will have to resort to other methods.

Restorative polishing

Restorative polishing is a professional complex body finish, which involves a series of procedures, aimed at restoring his condition. It is also called pre-sale, because it allows you to return the car to its original attractiveness.

Like any other business, polishing involves careful preparation

The right technology is based on a preliminary analysis of the surface and a complete map of measures, aimed at its restoration. It includes the following operations:

  1. Deep abrasive treatment to remove scratches and other mechanical defects. It is performed locally, if the condition of the body is acceptable, or globally, when it comes to a large number of small defects.
  2. Soft finish to remove micro-scratches, formed as a result of exposure to abrasive material, and obtaining a high-quality mirror surface.
  3. Protective - application of a finishing coating, which will protect LKP from negative influences.

Abrasive restoration is performed manually or with a grinder, special pastes and circles with a given degree of granularity. It is necessary, to ensure the necessary productivity and equality for all. Applying protective equipment is a light rub, which is best done manually.

What does abrasive polishing of a car look like?

Defect removal with abrasive materials is as follows:

  • first, wash the car thoroughly and dry it;
  • degrease the surface with white spirit, to remove substances, which could not be removed with a sink - tar, bitumen, machine oil, etc.. P .;

Mandatory, before you start polishing the machine, the body must be thoroughly washed, so that the smallest particles of dirt and dust do not deform the paint surface during the procedure

  • perform a detailed inspection of the body and use a washable marker to mark areas, which need to be processed;
  • lubricate the scratched area with abrasive paste with the maximum grain size;
  • take a grinder and apply a little paste on the circle, then polish with even, gentle movements, until the scratch disappears. At the same time, watch carefully, that the processed site had smooth exits - it should not accept a kind of deepening;
  • then use pastes and circles with decreasing grain size;
  • finishing involves soft finishing, to remove micro-furrows from previous materials;
  • the final stage is non-abrasive polishing, in which ceramic is used, Teflon, quartz polish or car wax as a finishing protective coating.

Polishing the body after painting

The technology of painting the car allows for some unevenness of the microrelief, which is expressed in the form of the following shortcomings:

  • shagreen;
  • petyoki;
  • powders;
  • varnish failures, etc.. P.

Experts say, that it is impossible to polish a car more than twenty times, after that it is recommended to update a paint and varnish covering completely

Therefore, the surface must be machined with polishes at the end, which aims to achieve a smooth mirror effect. It is not recommended to perform this procedure before 3-4 weeks after painting - during this time the enamel and varnish have time to finally harden and are ready for further work. In essence, post-painting treatment is no different from the restoration - it has the same tasks and the same technology.

Polishing car headlights and other elements

To return the surface to its original smoothness, ridding it of chips and abrasions on the surface of the paint, perform processing of a paint and varnish covering of one element:

  • door;
  • torpedoes;
  • wings, etc.. P.

The first thing to do is wash and dry the headlight

The same is done after painting of local character at painting of defects, the depth of which exceeds the thickness of the LCP. After that, they are covered with a layer of finishing polish, which lies in the form of a protective film. The tightness of such a film is a guarantee of minimizing the negative effects of moisture, ultraviolet, dirt, etc..

These types of treatments are used for varnishing wheels, chrome parts, cases of plastic elements of salon, dashboard, bumpers, etc..

Abrasive materials are used to restore optics. Scratches and chips also appear on it over time, which are caused by the following factors:

  • dust particles in the flow of oncoming air;
  • branches of shrubs;
  • blows of gravel and rubble, etc.. P.

If the defects are minor, you can try to polish the car headlights without sanding

Shallow micro-irregularities are eliminated with the help of a grinder and abrasive paste - this method is used for plastic and glass headlights. At the same time it is necessary to be very careful - at excessive number of turns of a circle glass can overheat and break.

Polishing car glass

It should be noted, that along with other elements of the car can be removed and protected from scratches and windows. With the help of polishes you can remove abrasions and scratches from the surface of any glass:

  • wind;
  • lateral;
  • rear.

As well as other elements of the car, glass is exposed to external mechanical factors. Example, from sand and dust, available in the flow of oncoming air, the surface of the windshield is erased, losing transparency - it is covered with a mesh of micro-holes and scratches.

Grinding allows you to remove scratches and other irregularities of the car glass

To return the glasses to their former smoothness and transparency, use the same polishing methods, which we discussed above. Using a grinder, abrasive pastes and circles remove the top thin layer of glass and its surface becomes smooth again.

When working with a grinding tool, be extremely careful with the number of revolutions. If it is too high, the glass may overheat and break. In this case, it will not be saved - just have to replace.

After the defects are removed from the glass surface, it is covered with special protective equipment - it can be anti-rain or other nanoceramic coating, which will be able to protect windows from new defects.

Polishing car plastic

As you know, on plastic small defects appear much faster, than on glass or metal - this material is soft and prone to various types of mechanical damage.

Today it is quite easy to polish plastic with your own hands, because there are a huge number of different tools on sale, as well as equipment

To clean the interior plastic, as well as plastic parts outside the car from scratches also use special polishes, able to return the material to its original smoothness and glossy shine.

Car polishing paste - how to choose

To choose a car polish, should first be determined, what parts you plan to process - for a body paint and varnish covering, headlight, glass or different materials are used for plastic.

If you need to get rid of small defects, to begin with you will need to use an abrasive - polish 3m, clay, GOI paste, etc.. P. The size of the grain depends on the depth and nature of the damage - the more scratches, the larger you need to choose the grain size. In accordance, the more there will be intermediate options, as risks and furrows from coarse abrasive are removed smaller.

After, how you returned the surface to its original smoothness, will need to be treated with a finishing protective layer, to provide protection against new damage. There are many options - some use liquid glass, others like waxing, there are supporters of polymer coatings.

The greatest demand among today are polishes with a pasty composition

When choosing a finish funds are usually guided by two criteria - naturalness or durability. Wax is a natural material, which, but, extremely short-lived - it needs to be updated regularly. Liquid glass lasts more than a year, however, it cannot be attributed to natural chemistry.

Do you need a car polisher?

The grinder is a tool, which is not a mandatory set, but its presence is highly desirable. Without a typewriter, productivity will be much lower - you will spend much more time manually on the same amount. in addition, in some cases you will not be able to ensure the necessary uniformity - to polish the headlights such a tool will be needed.

For such works the eccentric Pneumatic machine with the orbital scheme of movement of a working plane is usually used - it rotates not only around the axis., but also walks around it in a certain orbit. Practice has shown, that this type of grinder is the most convenient and productive in the described types of work.
