If you are looking for a reliable solution for restoring the appearance of your car without expensive polishing in the interior, this material will help you understand all the nuances.
Technical characteristics and composition of polish 3M 09374
Polish 3M 09374 belongs to the category abrasive pastes of medium aggressiveness. It is designed to remove oxidation, minor scratches, traces of bird droppings and other surface defects of the paintwork (paintwork). Unlike coarse polishing pastes, this composition does not damage the varnish layer when used correctly.
Main components included:
- 🔹 Microabrasive particles — provide mechanical removal of the top oxidized layer of varnish.
- 🔹 Lubricant additives — reduce friction during polishing, preventing surface overheating.
- 🔹 Polymer fillers — fill microcracks and create a protective layer.
- 🔹 UV filters — slow down the fading of paint under the influence of sunlight.
Key Product Parameters:
| Characteristics | Meaning |
|---|---|
| Type of polish | Abrasive (medium aggressiveness) |
| Release form | Paste in a jar 1 kg |
| Recommended polishing speed | 1200–2000 rpm |
| Compatible with paintwork | All types (acrylic, metallic, mother of pearl) |
| Protection period | Up to 6 months (with proper care) |
Important: polish 3M 09374 does not contain silicones, which makes it safe for further application of ceramic coatings or waxes.
What tasks is 3M 09374 suitable for: when to use it?
This polish is universal, but shows maximum effectiveness when solving specific problems:
✅ Removal of oxidation - if the body has lost its shine and become matte, 3M 09374 will return the original gloss in 1-2 treatments.
✅ Correction of minor scratches — copes with defects up to 3–5 microns deep (not affecting the soil).
✅ Preparation for protective coatings - ideal for the stage before applying wax or ceramics.
✅ Recovery after washing with aggressive shampoos — neutralizes the effects of using alkaline detergents.
But in what cases polish won't help:
- ❌ Deep scratches to metal (requires putty and painting).
- ❌ Severe corrosion (needs anti-corrosion treatment).
- ❌ Matte stains from chemical reagents (for example, after getting into acid).
Step-by-step instructions for use 3M 09374
Before starting work, prepare:
Polisher (preferably with variable speed)|Foam or felt pad (yellow or orange)|Soft, lint-free cloths|Insulating tape to protect plastic parts|Car body cleaner (e.g. 3M 08984)-->
Step 1. Washing and degreasing
Wash the car thoroughly two-phase shampoo (for example, Koch Chemie Green Star) to remove road dirt and grease deposits. After washing, wipe the body degreaser (isopropyl alcohol 70% is suitable). Do not use household detergents! — they leave a film that will interfere with polishing.
Step 2. Hidden area test
Apply a small amount of polish to inconspicuous area (for example, the inside of the door) and check the reaction of the paintwork. If streaks or cloudiness appear after polishing, reduce the speed of the machine or change the wheel to a softer one.
Step 3: Polishing
- Apply polish to a coin-sized circle.
- Distribute the composition over an area of ~50×50 cm using cross-shaped movements.
- Turn the machine on
1200–1500 rpmand polish until the defects disappear. - Increase speed to
1800–2000 rpmfor final finishing.
Step 4: Removing Residues
After polishing, remove excess with a soft cloth. no pressure. If white streaks remain, wipe the surface with microfiber soaked in quick detailer (for example, Meguiar’s Quick Detailer).
For complex defects (for example, spider webs from a car wash), use 3M 09374 in two stages: first with a yellow circle at 1500 rpm, then with an orange circle at 1800 rpm.
Comparison of 3M 09374 with analogues: which is better?
There are several popular polishes on the market that are similar in purpose. Let's look at their key differences:
| Polish | Abrasiveness | Protection period | Price (per 1 kg) | Features |
|---|---|---|---|---|
| 3M 09374 | Average | 4–6 months | ~2500 rub. | Universal, suitable for manual and machine polishing |
| Meguiar’s Ultimate Compound | Low | 3–4 months | ~2200 rub. | Less dusty, but less effective at removing oxidation |
| Farecla G3 | High | 2–3 months | ~1800 rub. | More aggressive, requires experience in polishing |
| Sonax Profiline EX 04-06 | Average | 5–7 months | ~3000 rub. | Works better on dark machines |
3M 09374 wins by ratio price/quality/versatility. It is suitable for both beginners and professionals, while Farecla G3 requires precision and Sonax noticeably more expensive.
What is the difference between 3M 09374 and 3M 09375?
Polish 3M 09375 - This is a more aggressive analogue with large abrasive particles. It is designed to remove deep defects (for example, after unsuccessful painting), but requires mandatory coating with a protective layer after treatment. 3M 09374 softer and can be used as a stand-alone solution.
Common mistakes when working with 3M 09374 and how to avoid them
Even experienced car owners sometimes make mistakes that ruin all their efforts. Here are the most common:
⚠️ Attention: Polishing in direct sunlight leads to instant drying of the composition and the appearance of holograms. Work in the shade or indoors!
🔴 RPM too high - at higher speeds 2200 rpm the polish begins to “burn”, leaving streaks. Optimal range: 1500–2000 rpm.
🔴 Insufficient defatting — if there are traces of wax or silicone on the body, the polish will not be able to distribute evenly.
🔴 Using one circle for all stages - for rough processing you need a yellow circle, for final processing - orange or white.
🔴 Skip the testing phase — without checking in a hidden area, the risk of damaging the paintwork increases 3 times.
Another critical error - polishing a dirty car. Sand and dust act like sandpaper, scratching the varnish. Always wash your car with clay bar before polishing!
If holograms (small circular marks) remain after polishing, remove them with a finishing polish without abrasive (for example, 3M 09376) at low speeds (800–1000 rpm).
How to extend the effect after polishing 3M 09374?
To make the results last longer, follow these recommendations:
- 🚿 Wash your car no more than once every 2 weeks - Frequent washing washes off the protective layer.
- 🧴 Use contactless shampoos (for example, Karcher RM 536) - they damage the polymer film less.
- 🌞 Park in the shade — UV rays destroy the binding components of the polish.
- 🛡️ Apply wax or ceramic over polish - this will double the protection period.
To maintain shine between polishes, use freshener sprays (for example, Turtle Wax Ice Spray Wax). They will not replace full polishing, but will prolong the effect for 1–2 months.
⚠️ Attention: Do not use after 3M 09374 polishes with silicone - they can react with polymer fillers, which will lead to clouding of the varnish.

FAQ: answers to frequently asked questions about 3M 09374
Can 3M 09374 be applied by hand without a polisher?
Technically yes, but the efficiency will be 3–4 times lower. For hand polishing use foam sponge and work in small sections, rubbing the compound in a circular motion. However, it will not be possible to remove deep defects without a machine.
How long does the polish take to dry after application?
The composition dries in 5–10 minutes at a temperature of +20°C, but complete polymerization takes up to 12 o'clock. During this period, avoid washing and contact with water.
Is 3M 09374 suitable for matte and satin paints?
No! This polish is intended for glossy paintwork only. For matte finishes, use specialized compounds, for example, 3M 09380 Matte System Polish.
Can 3M 09374 be used on plastic parts (bumpers, moldings)?
Yes, but with caution. Plastic is softer than metal, so polish at minimum speed (800–1000 rpm) and use black foam circle. Test the reaction in an inconspicuous area first.
How often can I polish my 3M 09374?
Optimal frequency - 1–2 times a year. It is not recommended to polish more often, since each time a microlayer of varnish is removed. Use protective sprays to maintain appearance between polishes.
