Polishing glass with Goya paste - features of polishing
Most of the glass, as well as the car body eventually acquire a plaque, because of which they become cloudy. This significantly reduces visibility on the road, and also adversely affects the appearance of the car. In this case, it is logical to periodically polish in a car repair shop or with your own hands. At this stage, each driver is asked a question: than to polish a surface?
Today there are all kinds of gels, paste, aerosols. Among the frequently used types of polishing agents are distinguished:
- wax;
- abrasive;
- polymeric.
The result of polishing the car glass
Each of the tools has its own characteristics. Wax and polymer rub the car to shine, creating on it protects the film from external influences. Abrasives are excellent for removing scratches and small cracks.
A universal remedy, used for polishing the surface of machines, there is a GOI paste. It is used for metal processing (in particular, precious), plastics, glass and mirrors with their own hands. Products in the form of a solid bar of green color are sold. The basis of GOI is chromium oxide.
The paste was invented in the 30s of last century. Today you can find green bars of pasta at the car market or in a specialty store as in jars 30 grams, and flakes on 1 kilograms.
Packing of pastes GOI
There are the following types of paste for polishing cars:
- №4. The most rude. It is used to eliminate noticeable abrasions, as well as scratches.
- №3. Prevents the appearance of opacity and gives a slight shine.
- №2, №1. The most effective types of GOI. They are able to give maximum shine.
To manually polish car windows from scratches or windshield, for which the products are most often used, you need to rub a soft piece of cloth with it and process the surface in a circular motion. To achieve maximum results, motorists often drip on the fabric (best of all - felt) oil-gasoline mixture.

Differences in grinding and polishing
Car owners need to know the clear difference between polishing and sanding.
Grinding is a rough method, which involves the impact on the surface of abrasive materials, which level the surface, removing a certain layer.
Grinding is used for that, to clean deep cracks and scratches, which cannot be masked by polishing. After rough sanding, the surface will look matte. To align it, it is necessary to use fine-grained after the big abrasive.
Polishing, unlike the previous process, is the next stage of grinding, less deep method of impact on the body, headlights or car windshield.
It can be carried out by any driver with his own hands, removing minor scratches from the front panel and giving it shine. Polishing is the application of a protective agent (paste, gel, aerosol, cream). In particular, polishing GOI provides:
- restoration of factory gloss of surfaces (windshield or side window, headlight, body);
- removal of minor scratches and cracks;
- creating a protective film with a dirt-repellent effect.
Diamond pastes for polishing
To determine, what kind of GOI for polishing you need, assess the condition of your car. If you see, that it has very small scratches, and the gloss decreased slightly, use the tool №3, which eliminates minor visual imperfections. Or use №№1 and 2, which are able to quickly give a presentable appearance of the car. If your car requires more thorough work due to the presence of deep scratches, use GOI №4 with good abrasive effect.
If you find it difficult to determine the condition of the vehicle by eye, scraping the surface of the car with a fingernail. If it clings to a scratch, the machine needs grinding, if not - it can be polished.

polishing features
The use of a pasty substance GOI has many nuances. Example, many drivers have questions: whether it is necessary to dilute the pasty substance with something? It is known, that it is quite firm and dense. The answer to this question is as follows: it is possible and even necessary. In order to easily apply the product on a rag, you need to make it thinner with machine oil. It is added at the rate of a few drops on a small piece of money.
Wax polish for the carPreparation of a solution of GOI paste
If you decide to polish the plastic surfaces of your car, use the softest cloth (flannel or cotton). To process a metal body, you can take a coarser fabric: jeans, felt or tarpaulin.
The polishing process involves the following stages with their features:
- before starting work it is necessary to degrease the surface with shampoo, alcohol or wiper. This will give a positive result when polishing;
- if on the front, there are scratches on the rear window or headlights, they will be much better to remove with an electric appliance, since work, made with their own hands, will not give the desired effect. Carrying out all the processes manually will not only take you several hours, but also will give the chance to remove only opaque headlights. Polishing machine, unlike working with your hands, performs the same amount of work in half an hour;
Polishing with GOI paste using a drill
- you need to prepare the workplace (remove dust from nearby surfaces - it may interfere with work);
- the substance should be applied to a small area of the windshield, headlights or body. Only after thorough rubbing of the product into the surface can you move on to the next section;
- after finishing work it is necessary to wash headlights or a body of the car again, using contactless foam (if grinding was performed) or strong water pressure (at usual polishing).
