When we talk about black in the automotive world, the imagination conjures up a deep, rich hue that absorbs light. However, there are materials whose ability to absorb light waves goes beyond the usual understanding of the physics of the visible spectrum. The blackest paint in the world is not just a pigment, but a complex engineering structure created at the atomic level.
Coverings such as Vantablack or Musou Black, are capable of absorbing up to 99.965% of incident light. This turns three-dimensional objects coated with this substance into flat two-dimensional silhouettes, lacking volume and detail. For car enthusiasts and engineers, this opens up new horizons, but also raises a number of practical questions about durability and applicability.
In this article, we will look at what is hidden behind the term “absolute black”, why conventional paints cannot compare with nanocoatings, and whether it makes sense to try to use such technologies for tuning the body of your car. You will learn about the physical properties of carbon nanotubes and how their chemical composition affects visual perception.
The physics of absolute blackness: how it works
Regular black paint works on the principle of absorbing most of the visible spectrum and reflecting the remainder, which our eyes perceive as color. Vantablack technology (Vertical Alignment Nano Tube Array) works differently. It consists of a “forest” of vertically oriented carbon nanotubes grown on aluminum foil.
When light hits such a surface, it is not reflected, but rather gets trapped between the nanotubes. The photons bounce repeatedly within the structure, losing energy with each collision until they are completely absorbed and converted into heat. That's why reflection of less than 0.035% of light makes the object visually indistinguishable from emptiness.
⚠️ Attention: Application of such coatings requires vacuum chambers and temperatures of about 400°C. It is impossible to recreate the structure of nanotubes at home.
There is also a pigmented version known as Vantablack VBx2, which is easier to apply, but is inferior in color depth to the original. Understanding the difference between chemical and structural light absorption is key to assessing application prospects.
Why do we see black?
Black is not a color in the usual sense, but the absence of reflected light. When an object absorbs all the photons in the visible spectrum, our brain interprets this as absolute blackness.
Main types of super black coatings
Today, the industry offers several solutions that claim to be the blackest material. The product of the British company has remained the leader for many years Surrey NanoSystems. However, competitors are not asleep, offering alternatives with different physical properties.
Particular attention should be paid to Japanese paint Musou Black (Black 3.0). Unlike the technical Vantablack, this is an acrylic paint with a high carbon content. It is available as a spray and can be applied to a variety of surfaces, including automotive interiors.

The choice of material depends on the goals. If you need to protect radiators from overheating or calibrate optical devices, expensive nanocoatings are suitable. For decorative purposes in a car, high-quality pigment analogues are often sufficient.
Application in the automotive industry
Although the main applications for ultra-black materials are in space, optics and the military industry, the auto industry is also showing interest in them. First of all, we are talking about reducing glare inside the cabin, which increases driver safety.
Company BMW already used Vantablack to cover the radiator grille of the BMW X6 concept car to demonstrate the depth of the form. However, such technologies are still too expensive and fragile for mass production of body parts.
It is more realistic to use such coatings in autonomous driving sensors. LiDAR lasers (LiDAR) must have reference black surfaces around them to avoid creating false reflections and accurately determine the distance to objects.
| Coverage type | Light absorption | Water resistance | Application in cars |
|---|---|---|---|
| Vantablack S-IRS | 99.965% | Low (requires protection) | Optics, sensors |
| Musou Black | 99.4% | Medium (acrylic) | Interior decor, emblems |
| Standard Black | 94-96% | High | Body parts |
Engineers are also exploring the possibility of using such paints to improve heat dissipation in high-tech electric vehicle components where temperature control is critical.
The automotive industry uses ultra-black coatings primarily for optical systems and glare reduction, rather than for exterior body paint.
Is it possible to paint a car Vantablack?
Theoretically, it is possible to cover a car, but in practice it is an extremely difficult task. Original Vantablack is not paint in the traditional sense. It is a growable structure that requires application to a special substrate under controlled conditions.
Even if we assume that you find a workshop with the necessary equipment, the result may disappoint the owner. The carbon nanotube coating is extremely fragile. Any mechanical impact, dust, raindrops or even strong air flow can damage the microstructure.
⚠️ Attention: The nanotube-based coating is destroyed upon contact with water and mechanical friction. Without a special protective varnish (which reduces the blackness effect), such “painting” will be washed off after the first wash.
For a car body, it is much more advisable to use high-quality black enamels with the “black sapphire” or “black mother-of-pearl” effect. They give deep color, but retain the glossy shine and protective properties necessary for use.
There are enthusiasts who have tried to apply Musou Black on hubcaps or interior elements. The result looks impressive in static form, but requires careful treatment comparable to museum exhibits.
Care and maintenance of super black surfaces
If you decide to experiment with available analogues of super-black paint on car parts, remember the main rule: no aggressive chemicals. The structure of such coatings is porous, and regular car shampoos can clog pores or dissolve the binder.
Cleaning should only be done with compressed air or a soft brush. Water is the main enemy for such surfaces, as it changes the refractive index in the pores, and the black color instantly turns gray.
- 🧹 Use only dry cleaning with low pressure compressed air.
- 🚫 Avoid getting oils, alcohol and solvents on the surface.
- 🌬️ Do not wipe the coating with fabrics, even microfiber - the lint can get stuck in the nanotubes.
It is almost impossible to restore the damaged area. Local coloring will be noticeable due to differences in the height of the “forest” of nanotubes or the density of the pigment.
Before applying any black paint, perform a compatibility test with the plastic or metal of the part on an inconspicuous area.
Economic feasibility and alternatives
Cost of surface treatment with original Vantablack amounts to thousands of dollars per square meter, not including the cost of application equipment. For an ordinary car owner, these are unreasonably high costs.
The market offers many alternatives that are visually close to ideal, but do not have the disadvantages of nanocoatings. Modern polyurethane films and matte paints can create the illusion of depth without the risk of losing properties after the first rain.
In addition, a black car in the sun heats up much more than a light one. Using a material that absorbs 99% of light will result in extreme heating of the body panels, which can negatively affect the paintwork of adjacent elements and interior comfort.
Why can't Vantablack be purchased in a can?
The original Vantablack is not a liquid, but a structure grown in a vacuum. Pigment versions (VBx2) exist, but they are protected by patents and sold only to selected partners for specific industrial applications.
Is there a blacker paint than Vantablack?
Yes, MIT researchers have created a material based on carbon nanotubes grown on sodium chloride, which absorbs 99.995% of light. However, this is a laboratory sample and is not intended for commercial use.
Is this paint hazardous to health?
In its finished form (after polymerization or fixation) the material is inert. However, the process of depositing nanotubes requires strict safety precautions, since free nanoparticles can be dangerous if inhaled.
Can Vantablack be painted over with regular paint?
You can paint over it, but the surface will first have to be carefully prepared, perhaps even sanded, since the smoothness and chemical properties of nanotubes can prevent the adhesion of ordinary enamel.
Where to buy Musou Black in Russia?
There may be no official dealers, but paint is often available through international marketplaces or specialty stores for artists and modellers.
