Restoring the shine of the paintwork is not just an aesthetic procedure, but an important stage of care that prolongs the life of the body. Well-chosen polishing It is able to work wonders, returning the car to the look of just descended from the conveyor. However, the wrong choice of means can lead to irreversible damage to the varnish, which will have to be corrected by expensive repainting.
The autochemistry market is full of offers from different manufacturers, and it is easy for a beginner to get confused in names and characteristics. In this article, we will discuss in detail how to choose an effective tool for your case, taking into account the condition of the coating and the type of equipment used.
First of all, it should be understood that polishing is the process of removing the microscopic layer of varnish along with defects. Therefore, the approach should be as competent and balanced as possible, so as not to remove excess.
Abrasiveness: the main criterion of choice
The main parameter to pay attention to is graininess or abrasiveness composition. It depends on the size of the abrasive particles how aggressively the tool will affect the surface. For deep scratches, coarse-grained compositions are required, and for the finishing gloss - microabrasives or even chemical cleaners.
Many manufacturers use color labels to indicate the degree of abrasiveness, which greatly simplifies navigation on store shelves. However, you can not rely only on the color of the bank, as the standards of different brands may differ.
- 🔴 Red usually denotes a rough abrasive for the primary processing and removal of deep drawings.
- 🟡 Yellow or white often indicates medium-abrasive compositions for basic polishing.
- 🔵 Blue or black usually means finishing polyrene with minimal grain.
- 🟢 Green can denote anti-hologram compositions or means for solid varnishes.
⚠️ Attention: Using a rough abrasive on a soft varnish without subsequent finishing is guaranteed to leave matteness and holograms visible in the sun.
Modern technology allows you to create smart-brasivewhich are destroyed in the process of work. Such pastes start with aggressive removal of the layer, and by the end of polishing turn into dust, providing a high gloss without switching to another circle. This greatly speeds up the process and reduces the risk of surface overheating.
Chemical composition and technology
In addition to mechanical action, many pastes work by chemical reaction. It's important to distinguish abrasive and abrasive (chemical) polishing. The first physically cut the irregularities, the second fill the micropores or dissolve the oxide layer.
Modern solid varnishes, which cover most new cars, often require special formulations with high solvent or nanoparticle content. They provide better lap sliding and more efficient defect removal.
A special place is occupied by compositions with content carnauba Or synthetic polymers. They are often marketed as “recovery polyrene” but are essentially hybrids that combine cleaning and protection in one step.
The myth of "recovery" polyroles
Many drivers believe that polymer can completely fill a deep scratch to the metal. In fact, filling is only possible at the level of microcracks of the varnish. If the scratch feels like a nail, no chemistry will remove it - you only need mechanical polishing or painting.
When choosing, the volatility of the components should be taken into account. Fast-evaporating solvents are good for professionals working quickly, but it is better for a beginner to take a composition with a longer work time to have time to evenly distribute the product over the body.
Classification by designation and stages
Professional polishing is rarely done in one stage. To achieve the ideal result, a step-by-step system is used, where each paste solves its task. Understanding this principle will help you choose the right set of tools.
The first step always involves removing the major defects. It's used here. cutting compound (separation composition). It leaves a matte surface that needs to be polished further. This stage is only possible on perfectly preserved bodies.
The second stage is polishing. The challenge here is to remove risk from the previous, rougher stage. Used polishes of medium abrasiveness, which return transparency to the lacquer.
| Phase | Purpose | Type of pasta | Tool. |
|---|---|---|---|
| 1. Recovery | Scratching, shaking, shaking | Rough abrasive (Cut) | A hard foam circle |
| 2. Polishing | Eliminating mattress, risk | Medium abrasive (Polish) | Mid-tough circle |
| 3. Finish | Deep gloss, holograms. | Microabrasive (Finishing) | Soft or fur circle |
| 4. Protection | Hydrophobe, protection | Wax or pottery | Soft fibre or sponge |
The final stage is critical for dark cars. It is in black that all the flaws of the previous stages are visible. Use of the holographic This is a prerequisite for obtaining a mirror effect.
☑️ Checking before buying pasta
Selection of pasta to the color of the car
The color of the body dictates its requirements for the choice of polishing chemistry. What is perfect for a white car can be useless or even harmful to a black car.
On dark bodies, especially black, graphite and dark blue, the most noticeable so-called "holograms" - micro-turbulence of the varnish, remaining after rough polishing. For such cars, you need to choose pastes marked hologram free Or "anti-hologram."
Lightweight cars, such as white, silver or beige, are more forgiving (forgiving mistakes). They show less risk and holograms. However, on a light background, bitumen spots and ingrained dirt are more clearly visible, so cleansing clays or special cleaners may be required here before polishing.
⚠️ For black cars, it is strongly recommended not to use universal “one-sided” pastes that promise results in one pass. The risk of rainbow shimmering in the sun is too great.
Red and green metallics require special attention to preserving the depth of color. Aggressive polishing can make the color fade. Here it is better to use pastes with the addition of oils, which temporarily mask the microrelief, making the color richer.
Equipment and compatibility of materials
The choice of pasta depends on what you are going to apply it. Manual polishing and machine polish require fundamentally different product characteristics. An attempt to polish the body with a handpaste machine will lead to rapid drying of the composition and damage to the LCP.
For rotary machines (with circular rotation) characterized by high surface heating. Therefore, pastes should be heat resistant and not "boil" instantly. Often for such machines use water-based compounds with a long operating time.
Two-way (orbital) machines are safer for beginners, but require more fluid pastes, since the amplitude of the circle is smaller. Modern synthetic polymers work perfectly here.
- 🛠️ Hard wool circles are used only with rough pastes on the rotor to remove the shaking.
- 🧽 Porous foam circles are suitable for most polishing and finishing pastes.
- 🐑 The microfiber is effective at removing persistent defects, but requires skill to keep the varnish from overheating.
It is also important to consider the compatibility of the paste with the material of the circle. Some formulations can clog the pores of the foam, reducing the efficiency of the work. In such cases, it is recommended to regularly clean the circle with a brush or use special spray cleaners.
Before starting work on the whole car, be sure to make a test pass on an area of 30x30 cm in an inconspicuous place (for example, on the threshold or at the bottom of the rack). This will help to understand the real effectiveness of the paste and the reaction of the varnish.
Mistakes in selection and use
Even buying expensive and high-quality polishingIt can be a result of misuse. The most common mistake is to apply too much composition. The paste should work, not swim on the body.
Another common problem is working on dry or already dried paste. This leads to the appearance of deep scratches with abrasives. Always monitor the condition of the mixture on the surface, sprinkling it with water if necessary (if the instructions allow) or adding a fresh portion.
Do not try to save money by buying cheap abrasives of unknown brands. They often use uncalibrated abrasives (such as fine sand or low-quality aluminum oxide) that leave a chaotic and deep risk that cannot be removed by finishing lineups.
Remember: quality pasta is expensive, but it is spent economically (usually peas are about 40-50 cm in size) and gives a predictable result.Ignoring surface preparation is a fatal mistake. Polishing a dirty or low-fat body will cause you to carry dirt around the varnish, creating new defects. Washing, claying and degreasing are mandatory.
The quality of polishing depends on 80% of the body preparation and correctness of the selected bundle "pasta-circle-machine", and only 20% of the brand of the chemistry itself.
Frequently Asked Questions (FAQ)
Can I polish my car with a regular toothpaste?
Theoretically, toothpaste contains abrasive, but it is unpredictable for car lacquer. It can leave a mattress that is difficult to remove. In addition, it does not have components that facilitate the slip and protect the rubber seals. It is better to buy specialized, albeit inexpensive, polymer.
How often can you polish a car?
Complete abrasive polishing with varnish removal is not recommended to do more than once every 2-3 years, since the layer of the LCD is not infinite. Recovery polishing (light) can be done as defects appear, but with minimally aggressive formulations.
What is the difference between polish and wax?
Polyrene (especially abrasive) is designed to remove defects and change the surface relief. Wax or sealant create a protective film from above, not removing scratches, but only masking them and protecting them from the external environment. These functions are often combined in different stages of care.
Do I need to degrease the body after polishing?
Yes, I will. After polishing, the remains of paste, oils and lacquer dust remain on the surface. Degreasing (antisilicone) is necessary in order to see the real result and correctly apply the final protective coating (wax or ceramics), otherwise it simply will not lie down.
