Car owners often face the desire to change the appearance of their vehicle, making it more aggressive and modern. One of the most popular ways of tuning becomes chrome-blackingIt allows you to hide the excessive shine and give the car a characteristic style of "Black Edition". This procedure does not require complex equipment and can be performed independently with basic skills and quality materials.
There are several proven ways to implement this idea, from simple and temporary solutions to capital changes using professional chemistry. The choice of a specific method depends on what part needs to be processed: grille, moldings, nameplates or wheels. It is important to understand that chromium It is a complex coating that requires proper surface preparation for long-lasting results.
In this article, we will analyze in detail all available options for dimming, compare their cost and durability, and give step-by-step instructions. You'll find out why. tinting It may be better than film in some cases, and why spray-film It is ideal for experimentation. A deep understanding of the processes will help you avoid typical mistakes and get the perfect black gloss or noble mat.
Why do owners darken chrome elements
The main reason for the popularity of this procedure lies in the aesthetics. Chromium elements, which were previously considered a sign of luxury and prestige, are now often perceived as a relic of the past or an element of "kolkhoz" tuning. Darkening allows you to remove cheap shine and make the car visually more strict, expensive and sporty. This is especially true for black, grey and dark blue cars, where black chrome looks most harmonious.
In addition to the visual effect, there is a practical aspect. The chromium coating may eventually fade, become covered with a "spider web" of small chips or become oxidized. Chromium blackout It is a great way to reanimate the appearance of parts without replacing them. Applying a protective layer, whether it is a varnish or a dense film, creates an additional barrier to aggressive external environments, reagents and ultraviolet light.
Also worth mentioning is the trend for styling to factory versions of Night Package or Black Line. Many car manufacturers offer such packages optionally, but their cost is high. Self-dimming allows you to get a similar result for fraction of the price. However, it is important not to overdo it: excess black can make the car gloomy, so often use combined solutions.
- 🎨 Aesthetics: Giving the car a modern, aggressive and expensive appearance, compliance with fashion trends.
- 🛡️ Defense: Hiding defects of old chromium and creating an additional protective layer against corrosion and reagents.
- 💰 Savings: The ability to get the look of an expensive factory version of the "Black Edition" without buying a new car or expensive original parts.
- 🔄 Individuality: Flexibility in the choice of hue (from translucent smoke to deep black) and texture (gloss, mat, satin).
⚠️ Caution: Full black coloring of chrome elements can be regarded by traffic police inspectors as a change in design, if the color of the car in the documents does not coincide with reality (although this is rare for small details). However, dimming of headlights or lighting devices must strictly comply with the standards of light transmission, otherwise a fine and removal of numbers are guaranteed.
Review of methods: from film to chemical deposition
In today’s automotive tuning market, there are four main ways to change the color of chrome parts. Each of them has its advantages, disadvantages and scope of application. The choice of method depends on your budget, the desired coverage life and your willingness to undertake time-consuming processes.
The easiest and most affordable option is to use tinting-film. It comes in different shades (from light haze to deep black) and textures. The film is good because the process is reversible: at any time it can be removed, returning the details to their original appearance. However, on difficult reliefs and sharp corners, it is almost impossible to glue the film without heating and special skills.
The second popular method is spray film (liquid vinyl). These are aerosol compounds based on rubber, which are applied in several layers and after drying form an elastic rubber-like coating. The main advantage is the ability to remove the coating with one layer ("stocking") at any time. Spray film falls perfectly on complex forms, but is less resistant to mechanical damage and washing under high pressure compared to varnish.
The third option is tinting. This is the most durable solution, which is actually a painting. Lacquer creates a solid, glossy coating, indistinguishable from factory black chrome. The downside is one, but significant: you can remove the varnish only by abrasive method (polishing) or chemistry, which can damage the underlying chrome if you act carelessly.
Finally, there are professional methods such as PVD spraying (physical deposition from the gas phase) in vacuum chambers. This is a factory technology that cannot be repeated in garage conditions. It gives the highest quality and wear-resistant "black chrome", but requires dismantling parts and treatment in specialized centers.
⚠️ Note: When choosing a spray film, be sure to check its compatibility with plastic. Cheap solvent-based formulations can react with certain types of plastics, causing them to break down or cloud. Always do the test in an inconspicuous area!
Comparative table of dimming methods
To make it easier for you to decide on the choice, we have prepared a summary table comparing the key characteristics of popular methods. Please note that the service life is approximate and depends on the vehicle operating conditions and the quality of materials.
| Method | Term of service | Difficulty applying | Reversibility | Cost |
|---|---|---|---|---|
| Tonic film | 2-5 years | Medium (skill required) | Complete (without traces) | Low/Mediocre |
| Spray film | 1-2 years | Low (spray ball) | Full (taken off with a stocking) | Medium |
| Tonic varnish | 5 years | High (requires paint) | Low (surfing only) | Medium/High |
| PVD spraying | 10 years. | Professional | Impossible. | Tall. |
As can be seen from the table, spray film is ideal for a temporary effect or frequent image change. If you want to make a car for the ages and do not plan to sell it in the near future, then tinting It's the best choice. The film occupies a middle ground, offering a good balance between durability and the possibility of returning to the stock.
It is also important to consider the state of the parts themselves before starting work. If chromium has already started peeling or has deep scratches, then transparent or translucent methods (light smoke) can only highlight the defects. In such cases, either a complete restoration of chromium or the use of covert black materials is required.
The myth of "washable" chromium
It is believed that chromium can be simply washed off with a special acid, leaving black plastic under it. It's dangerous! Under the chromium is often a copper sublayer or nickel, which without the top layer will instantly oxidize and rust. In addition, the acid can eat the base metal or plastic part.
Technology of applying tinting film
Sticking vinyl film is a process that requires purity, patience and a set of tools. You will need: the film itself (preferably with channels for air exit), rakel (drill), construction hair dryer, knife with interchangeable blades, degreaser and napkins without pile.
The first stage is the surface. The part must be thoroughly washed, dried and degreased. Any dust left under the film will be visible as a bump. If there are chips or scratches on the chromium, it is better to pre-polish them with fine sandpaper (P2000) and polish, otherwise the film will repeat the relief.
The process of pasting begins with cutting the material. The film is cut with a margin of 2-3 cm at the edges. Then, removing the protective layer, it is carefully applied to the detail. With the help of a hair dryer, the film is heated (but not overheated so as not to damage the adhesive layer or vinyl structure) and stretched, fitting complex shapes. The air is driven out by a rackel from the center to the edges.
- 🧼 Degreasing: It's a critical phase. Use isopropyl alcohol or a special degreasing agent. Do not touch the fat-free surface with your hands.
- 🌡️ Temperature: It is best to work at an air temperature of +18 ... + 25 ° C. In cold, the film becomes stiff and can crack when stretched.
- ✂️ Undercut: The edges of the film are cut with a knife after the part is completely cooled so that the material does not tighten and open the edge of chromium.
⚠️ Note: Do not use a hair dryer at maximum power at one point for a long time. The film can be deformed ("story"), and the adhesive layer - lose its properties, which will lead to peeling in the future. Keep your hair dryer moving.
☑️ Checklist for tape pasting
Working with spray film and varnish
If the film requires "man-making", then working with liquid compositions more like a classic painting, but with its nuances. For spray-film (Liquid vinyl) preparation is critical. The part should be perfectly clean and dry. Printing is not usually required, as the lineup is the base and finish.
Apply spray film need to be in several thin layers. The first layer is “dust”, it creates adhesion (adhesion) with the surface. It dries quickly, literally 10-15 minutes. Then 3-5 full layers with interlayer drying are applied. It is important to keep the balloon at a distance of 20-30 cm and make smooth movements to avoid leaks. The final layer can be made a little thicker to obtain a glossy effect (if the material allows it).
S tinting-varnish It's more complicated. Here you need a two-component system (varnish + hardener) and, preferably, spray gun for uniform application. The lacquer gives a chemical reaction when drying, becoming very hard. Before applying the varnish, a special tinting soil or base is often used to achieve a rich black color. Grinding between layers (interlayer) with water with abrasive P2000-P3000 allows you to remove the shaft and achieve mirror shine.
The main rule when working with chemistry is safety. Pairs of varnishes and sprays are toxic. It is necessary to work in a well-ventilated room, in a respirator and protective glasses. Getting the composition on the skin or in the eyes is unacceptable.
The secret of the perfect gloss: If you use tinting varnish, after drying completely (after 24-48 hours), polish the surface with abrasive paste. This will remove micro scratches and dust, making the part indistinguishable from the factory black chrome.
Recovery and care for darkened details
Even the best quality blackout requires proper care. Chromium under the film or varnish does not disappear anywhere, and if moisture gets to it through a microcrack, corrosion will begin, which will lift the coating from the inside. Therefore, regular inspection of details is mandatory.
When washing your car, avoid the use of aggressive chemicals, alkaline shampoos and abrasive sponges. For spray film, solvents (gasoline, acetone, solvent) are especially dangerous - they can dissolve the coating. Film and varnish is better to wash with shampoos with neutral pH and wax. This will create an additional hydrophobic layer from which water and dirt will drain.
If you notice damage on the film (bullyers, blisters), do not delay repair. A small defect can be glued by heating the edge with a hairdryer and pressing. If the varnish is damaged, local polishing or repainting of the element will be required. The spray film at the site of the damage can be easily painted, applying a new layer of canister, pre-wrapped the edges of the damage.
Regular processing of darkened parts with ceramics or liquid glass extends their service life by 1.5-2 times, protecting them from ultraviolet light and reagents.
Frequently Asked Questions (FAQ)
Can I darken the chrome without removing the parts from the car?
Theoretically, it is possible, especially if you use spray film or work carefully with film. However, the quality will be lower. For the ideal result, the details (grating, moldings, nameplates) are better removed. This will allow you to process them from all sides, avoid getting paint on the body and dry the material qualitatively from all sides.
How to remove the tinting varnish if the result is not liked?
The most difficult thing to remove is the varnish. The mechanical method (grinding) is risky, since you can strip the chrome itself. The chemical method involves the use of washes for paint, but they can be aggressive to the plastic base. It is often easier and cheaper to buy a new chrome-plated part than to try to save the old one after a failed painting.
Is it true that black parts warm more in the sun?
Yes, black absorbs more heat. However, for external decorative elements (grating, window edging), this is not critical. The temperature of the plastic or metal under the coating will rise slightly and will not affect the engine operation or the integrity of the body. It is worth to fear only dimming the headlights, where overheating can reduce the life of the lamps.
How much does it cost to dim chromium in a professional service?
The price depends on the method and scope of work. Observance film grille can cost from 3000 to 8000 rubles. Painting in black chrome (varnish) will cost more - from 5000 to 15000 rubles per element, as it requires more preparation and materials. Dismantling and installation are often paid separately.
