The car shines after polishing, but this is a purely aesthetic side of the issue. The main thing is that polishing compounds block the way for moisture and., harmful impurities, which means that they faithfully serve the body. Simply applying a polishing compound to a dried body is still not enough. The wax films themselves (polishing compounds are usually made on the basis of wax) almost always matte and in order for the car to play, to shine under the rays of the sun, it is necessary to work hard, polish the applied composition. The mechanics of this process is as follows: polishing with a soft cloth (flannel is best), we rub the composition into the pores and microcracks, while smoothing the surface film. The heat generated during rubbing melts the surface, and the abrasive particles that are part of the polishes even out the existing irregularities. Thus, a protective layer is created on the surface of the body, which serves as a reliable barrier to oxygen, water, ultraviolet rays, washing solutions, etc., trying to penetrate into it.
If the body is regularly washed and polished, the car pays handsomely. Firstly, the body lasts longer, and this is cost-effective. Secondly, the aerodynamic qualities of the car are improved by reducing friction, and consequently, fuel consumption is also reduced. Thirdly, dirt and water, having no adhesion to the surface, roll off, and the car is less polluted. These are just some of the benefits of polishing, and the list goes on.
Polishing preparations are divided into «Polishes for new coatings», «Polishes for weathered coatings» and «Polishes for old coatings». Since the new coatings are smooth, shiny, without scratches and microcracks, the role of the coating is to obtain a durable protective film. It usually lasts a few (five six) sinks, repels fashion well, in short, provides such conditions that the condition of the paintwork is not disturbed.
Time passes, and you suddenly notice that no amount of effort applied during polishing, does not provide the former shine. It seems that the body has developed immunity to «Polishes for new coatings». Usually this condition occurs after 2-3 years. Adjustments to the terms can be made by the conditions of operation and storage. The loss of its former brilliance is nothing more than the result of oxidation and the onset of destruction of the surface layer of paint. Of course, without having abrasive particles in the composition of the polish, you cannot remove the resulting veil from the surface of the body. «Polishes for weathered coatings», in addition to all the necessary components to provide a protective film, they also have a soft abrasive. He is the main cleaner. Having processed the body with this composition, having achieved the main goal - removing the oxidized layer, you can use it again «Polish for new coatings», to record what you've done.
When polishing a car body, it should be remembered that it is necessary to obtain a non-sticky, even, shiny protective film.
You will not get it if the body is poorly washed, if the composition is applied in a thick layer, if it is overdried or not completely dried. The instruction for the drug specifies the conditions for application and polishing. Following it, you will get a surface that will not have streaks, traces of touch, and dust will not stick to it.
