Body polishing is an essential step in car care, which returns shine to the paintwork, eliminates microcracks and protects against corrosion. But the result directly depends on the choice of paste: an unsuitable composition may not only fail to cope with defects, but also aggravate them, leaving a hologram on the surface or even rubbing the varnish down to the ground. In this article we will look at how to choose pasta according to type of damage, body material and budget, and we will also test popular brands - from budget (3M, Turtle Wax) to professional (Menzerna, Scholl Concepts).
Let us warn you right away: there is no universal paste. What is ideal for deep scratches on a dark car may be too aggressive for a light metallic or useless for soft plastic bumpers. We have compiled step-by-step selection method, which will help to avoid mistakes, and also collected feedback from detailing masters about the real effectiveness of the compositions. At the end of the article there is a checklist for purchasing and answers to frequently asked questions.
Abrasive vs non-abrasive pastes: what is the difference and what to choose
The main division of polishing pastes is based on the presence of abrasive particles. Their size and concentration determine which defects the composition can handle.
Abrasive pastes contain microparticles (aluminum oxide, silicon carbide, diamond chips) that physically cut off the top layer of varnish. They are divided into:
- 🔹 Rough (abrasive size 5-10 microns): for removing deep scratches, oxidation, sandpaper marks
P1500–P2000. Example: Menzerna Power Finish 400. - 🔹 Average (3–5 microns): eliminate minor marks, abrasions, stains after washing. Popular: 3M Perfect-It EX, Farecla G3.
- 🔹 Small (1-2 µm): final polishing before applying protective coatings. Example: Scholl Concepts S30+.
Non-abrasive pastes (they are also called “finilki”) work due to chemical components - polymers, waxes, silicones. They do not cut off the varnish, but fill micropores, leveling the surface and adding gloss. Suitable for:
- 🚗 Caring for new or almost perfect cars.
- 🚗 Consolidates the result after abrasive polishing.
- 🚗 Quick color refresh before sale.
⚠️ Attention: Non-abrasive pastes do not remove scratches - they only mask them due to light refraction. The effect lasts for 2–4 washes, after which the defects become noticeable again.
How to choose? If there is one on the body scratches visible in the light (you can feel them with your fingernail), you need an abrasive paste. For prevention or preparation for application of ceramics, non-abrasive ceramics are sufficient.
How to choose a paste based on the type of paint coating
Modern paintworks are divided into soft (most Japanese and Korean cars) and hard (German premium brands, some American models). An error in choosing a paste can lead to rubbing the varnish down to the ground using a polishing machine in 1–2 passes.
| Type of paintwork | Examples of car brands | Recommended paste | What NOT to use |
|---|---|---|---|
| Soft (1–2 layers of varnish) | Toyota, Honda, Kia, Hyundai | Ultra-soft abrasives (1–1.5 microns): Scholl S20+, CarPro Essence | Coarse pastes (>3 µm), hard polishing wheels |
| Medium hard | Volkswagen, Skoda, Ford | Medium abrasive (2–3 microns): 3M Perfect-It EX, Farecla G3 | Diamond pastes, compositions for removing holograms without dilution |
| Hard (multilayer varnish) | BMW, Mercedes, Audi, Porsche | Aggressive abrasives (up to 8 microns): Menzerna Power Finish, Mirka Polarshine | Non-abrasive pastes as the main product (only for final processing) |
How to determine the hardness of paintwork? Do a test: drop water on the hood. If the drop spreads quickly, the coating is soft; if it holds its shape, it’s solid. Also pay attention to the year of manufacture: cars older than 2010 often have a thinner layer of varnish.
Before polishing, check the thickness of the paintwork with a thickness gauge (optimally 80–120 microns). If it is less than 60 microns, it is better to refuse abrasive polishing: the risk of rubbing to the metal is too high.

Step-by-step instructions: how to polish a car with paste correctly
Even the most expensive paste will not give results if the technology is violated. Follow this algorithm:
Select a paste according to the type of paintwork and defects | Wash and degrease the body (use isopropyl alcohol 70%)|Seal the plastic and rubber with masking tape|Prepare a polishing machine (speed 1000–1500 rpm)|Divide the body into zones (for example, hood, fender, door)-->
Step 1. Test pass. Apply the paste to a small area (20x20 cm) and make 2-3 passes with the machine. Check:
- 🔍 Have holograms appeared (small circular risks).
- 🔍 Is the varnish overheating (if the surface becomes sticky, reduce the speed).
- 🔍 Is the paste aggressive enough for your defects?
Step 2. Basic polishing. Work in a crisscross pattern (first horizontally, then vertically), holding the machine at an angle of 5-10°. Important details:
- 💧 Add paste as it dries (every 30-40 seconds).
- 🔄 Do not put pressure on the car - the weight of the tool is sufficient.
- ⏱ Time per area: 1–2 minutes (longer - risk of overheating).
Step 3. Monitoring the result. Wipe the surface with microfiber and inspect from different angles. If scratches remain, repeat with a more abrasive paste. After successful polishing, apply protective coating (wax, ceramics) within 24 hours.
⚠️ Attention: Never polish in direct sunlight! The paste dries instantly and the varnish overheats. Optimal temperature for work: +15…+25°C.
Common mistakes when polishing and how to avoid them
Even experienced car owners make mistakes that spoil the results. Here are the most critical ones:
1. Use one paste for all defects. For example, trying to remove a deep scratch with a non-abrasive paste or polishing soft varnish with a coarse abrasive. Consequences: uneven shine, worn areas, need to repaint.
2. Wrong choice of polishing wheel. Hard circles (orange, yellow) are combined only with abrasive pastes, soft (white, gray) - with finilki. The error results in:
- 🔴 Too aggressive cutting of varnish (hard circle + rough paste).
- 🔴 Zero effect (soft circle + abrasive paste).
3. Polishing a dirty car. Sand and dust act like sandpaper, scratching the varnish. Degreasing isopropyl alcohol definitely even after washing!
4. Ignoring the final defense. After polishing, the varnish remains unprotected. Without wax or ceramics, it will quickly become covered with microcracks from UV rays and road chemicals.
What to do if the varnish is overheated?
If the surface becomes sticky or cloudy, immediately:
1. Stop polishing and cool the area with a damp microfiber cloth.
2. Apply restorative paste (eg CarPro Denim) at low speeds (800 rpm).
3. If the varnish has been rubbed down to the primer, only repaint the part.
Polishing by hand vs machine: which is more effective?
Hand polishing is only suitable for non-abrasive pastes or caring for small areas (headlights, mirrors). Benefits:
- ✅ There is no risk of varnish overheating.
- ✅ Cheaper (no polishing machine needed).
- ✅ Can be done in the garage without electricity.
Disadvantages:
- ❌ It is impossible to remove deep scratches.
- ❌ Time consumption: 3-5 times longer than with a typewriter.
- ❌ Uneven result (stains, underpolished areas).
For abrasive polishing a machine is required. Optimal parameters:
- 🔧 Power: from 800 W.
- 🔧 Speed: 1000–2000 rpm (for finishes - up to 3000).
- 🔧 Weight: 1.5–2 kg (light machines vibrate, heavy ones get tired).
Budget version of the machine - Makita 9227C (≈5 thousand rubles), professional - Flex PE14-2-150 (≈20 thousand rubles).
FAQ: Frequently asked questions about polishing pastes
Can you polish your car with toothpaste?
Toothpaste contains a fine abrasive (calcium carbonate), but its effectiveness is extremely low. It can slightly lighten scuffs on headlights or chrome, but it is useless for the body. Moreover, bleaching pastes contain chemical components that destroy the varnish.
How much paste do you need for one polish?
Consumption depends on the size of the machine and the type of paste:
- 🔹 Abrasive: 30–50 g per sedan (approximately 1/3 can Menzerna 250 ml).
- 🔹 Non-abrasive: 15–20 g.
Advice: apply the paste to the circle, not to the body - this way the consumption is less.
What is the difference between paste for dark and light cars?
For dark cars (black, blue, green) need pastes with fine abrasive (1–2 microns), since even microscratches are visible on them. For light ones (white, silver) coarser compounds (3–4 microns) are suitable, since defects are less noticeable. The exception is metallic: it is polished like dark colors.
Is it possible to polish a new car?
New cars (up to 3 years old) usually do not need abrasive polishing. Enough:
- 🔹 Non-abrasive paste for removing factory stains.
- 🔹 Application of protective coating (ceramics, liquid glass).
Exception: if the paintwork has defects from the factory (for example, “orange peel”).
How to store polishing paste?
The shelf life of the paste is 2–3 years, but only if stored correctly:
- 🔹 Temperature: +5...+25°C (do not freeze!).
- 🔹 Airtight packaging (after opening the can, use cling film under the lid).
- 🔹 Away from direct sunlight.
If the paste has separated or changed color, it cannot be used.
