GYEON product features and construction philosophy

Overview of GYEON as a professional chemical brand
GYEON is a globally known professional chemical brand from Korea. Its distinctive feature is its approach
to scientifically removing and protecting paintwork using chemical reactions, rather than the traditional “sensory car wash.” The appeal
of GYEON is that even average users can replicate the quality used by professional installers.
For this reason, the ingredients, reactivity, and application procedures are designed in a very logical way, making it easy for anyone to achieve consistent results.
The role and purpose of each product

The GYEON series consists of three easy-to-use products for home use: IRON, BATHE+, and WET COAT. These are the basic components that support the chemical car washing process.
- IRON : Iron powder remover.
Dissolves and removes brake dust and metal powder through a chemical reaction. - BATHE+ : A shampoo cleaner that
removes dirt and forms a water-repellent film at the same time. - WET COAT : Instant coating protectant.
Uses the moisture left after washing the car to create a water-repellent film on the surface.
By using these products in the correct order, you can complete a “scientific car wash cycle” that lifts and removes dirt and prevents it from re-adhering.
Benefits of scientific car washing
With conventional “brute force car washes,” it was impossible to avoid minute scratches caused by sponge friction.
However, GYEON products are primarily based on chemical reactions, which break down and remove dirt, minimizing physical friction.
As a result, the gloss and transparency of the painted surface can be maintained for a long period of time, and the frequency of reapplication (recoating) can be reduced.
In other words, the true value of GYEON lies in the idea of ”car washes that protect with science.”
Iron removal process: Chemical reaction and management of GYEON IRON

The properties and adhesion mechanism of iron powder stains

Iron particles that adhere to car bodies are mainly caused by brake dust and metal particles around factories.
When driving at high speeds or in city streets, fine iron particles in the air are attracted to the paint surface by static electricity, and if they oxidize, they become brown, dot-like stains.
If left unattended, they can penetrate the paint film and become impossible to remove even by polishing.
A major feature of GYEON IRON is that it safely dissolves and removes these iron particles through a chemical reaction, rather than physically scraping them off.
GYEON IRON
GYEON IRON reaction principle
IRON is a chemical remover that reacts with iron ions and turns purple.
When sprayed, it dissolves iron particles adhering to the painted surface, turning purple, allowing you to visually confirm that the reaction is underway.
This “purple discoloration” occurs due to a chemical reaction between the iron and the agent, allowing the dirt to be lifted without the need for scrubbing with a brush.
Furthermore, its neutral formula, which is not too acidic, means it has little effect on paint or plastic parts, making it a safe option.
Appropriate application amount and leaving time
It’s not the case that “the more you spray, the better” when it comes to IRON.
The appropriate amount of spray per panel is enough to lightly wet the entire surface, and the ideal reaction time is within 5 minutes.
On hot days, it dries quickly, so it’s safe to rinse with water as soon as the reaction begins in 2-3 minutes.
Leaving it to dry can cause stains, so it’s recommended to apply it in a shady, well-ventilated area.
Auxiliary Cleaning and Environmental Control
Lightly rubbing with a brush or sponge while the product is reacting will efficiently remove iron particles from uneven areas.
However, the trick is to only rub the surface lightly, without rubbing too hard.
Also, since IRON may also react with concrete and the ground when dissolving the iron particles, it is a good idea to protect the floor of the application area by sprinkling water on it.
The final step in removing the iron particles is to rinse the chemicals completely with a stream of water.
Cleaning process: Shampooing with BATHE+ and preventing dryness

BATHE+ features and dilution ratio
GYEON BATHE+ is not just a car shampoo, but a hybrid type that simultaneously cleans and protects.
In addition to its cleaning ingredients, it also contains a siloxane-based water-repellent ingredient, which forms a thin film every time you wash your car. The
basic dilution ratio is 2-3 capfuls per 10L bucket, but this can be adjusted depending on the temperature and size of your car.
A slightly stronger solution (3 capfuls) is sufficient in summer or dry environments, while a thinner solution (2 capfuls) is sufficient in winter or in the shade.
Emphasis on film formation rather than bubbles
Many people tend to think that “good foaming = cleaning power,” but the correct answer with BATHE+ is not to create too much foam.
Even though it foams moderately, the surfactants penetrate under the dirt and lift it away.
Furthermore, a water-repellent film is formed at the same time as cleaning, reducing friction when wiping and preventing fine scratches.
Rather than focusing on foam, the key is to spread the liquid while paying attention to how it spreads.
Measures to prevent dryness during summer construction
The important thing to remember when using BATHE+ is not to let it dry.
In direct sunlight, the water evaporates quickly, which can cause stains. For this reason, it is best to wash each panel in order,
starting with the hood, then the front fenders, then the doors, and then rinse immediately with plenty of water . The finish depends on not leaving any foam on the panel for a long time, and rinsing it with plenty of water immediately after washing.
Tool selection and construction techniques

The basic rule is to use a fine-meshed car wash sponge and separate one for the body and one for the wheels.
Choosing a thick, highly absorbent microfiber cloth will help prevent water droplets from remaining.
Spray application, where you put the diluted solution in a spray bottle and spray it directly onto the body, is also effective, but as this can easily result in uneven coverage, the trick is to treat small areas at a time and then rinse immediately with water.
BATHE+ is a product that “coats while washing,” so by using it frequently, you can see the paint’s gloss gradually increase.
Water repellent and protective process: Surface treatment with WET COAT

Application principle – Instant film formation through siloxane bonding
GYEON WET COAT is a protective agent that instantly forms a water-repellent film when sprayed on a wet car body after washing.
The secret lies in a chemical reaction called “siloxane bonding.”
The sprayed liquid reacts with water to create a thin glass-like film on the paint surface, providing strong water repellency and gloss.
It sets in just a few seconds, eliminating the need for a wiping process like with wax.
The rational system of “applying while wet” is a scientific approach typical of GYEON.
Tips for preventing unevenness on dark-colored cars

For body colors such as black and dark blue, the amount of liquid sprayed and the water flow control will determine the final result.
Spraying too much will leave unevenness and cloudiness, so about two pumps per door is the appropriate amount.
Applying high-pressure water immediately after spraying will ensure the agent is dispersed evenly and prevent unevenness.
Also, avoid application in the hot sun and ideally work when the body is cool.
Checking water repellency and drying time
Immediately after application, you can check the effectiveness by observing the water droplets bouncing off.
If the water droplets roll off, it means that a uniform film has been formed.
After that, it is fine to let it dry naturally, but wiping it lightly with a towel will enhance the gloss.
It takes about 3 hours for the product to fully harden.
Durability will be further improved if you take care to avoid exposure to rain or dew.
Coating application to cars and maintenance use
WET COAT can be applied over existing glass coatings or polymer-based coatings.
By layering a “protective film” on top of the existing coating, it prevents deterioration of the base layer and is also excellent as a maintenance coat.
Using it about once a month will maintain the water-repellent effect and keep the painted surface smooth at all times.
For the finishing wipe after application, use a soft microfiber cloth and wipe gently to absorb the moisture without leaving any unevenness.
The final step of the glossy finish
The effect of WET COAT is not only water repellency, but also a deep gloss.
After the moisture has evaporated, a light dry wipe will enhance the transparency, giving the entire body a clear impression.
This “gloss created by a chemical reaction” is different from wax or polymers in that it does not become uneven even when layered.
As it provides reliable water repellency and protection in a short amount of time, it is an extremely suitable product for daily maintenance.
Finish evaluation and scientific maintenance design

Overall evaluation of water repellency, stain resistance, and gloss
The finish achieved after using GYEON products in stages is visually and scientifically stable at a high level.
First, the water-repellent effect of WET COAT lasts for approximately three months, maintaining a “super water-repellent” state where water droplets roll off the surface in small droplets.
At the same time, the cleaning ingredients in BATHE+ make it difficult for oil film and pollen to adhere to the surface, improving stain resistance.
It also prevents the re-adhesion of iron powder and oxides removed by IRON, leaving the painted surface incredibly smooth to the touch after application.
As for gloss, it features the transparency unique to inorganic coatings and uniform light reflection.
Chemical compatibility and film stability
The order of IRON → BATHE+ → WET COAT has a precise chemical meaning.
The IRON removes metal contaminants, and the BATHE+ cleans and neutralizes the interface, allowing the siloxane bonds of the WET COAT to be fully utilized.
By adhering to this order, the “chemical consistency” between the coatings is maintained, improving the adhesion and durability of the film.
Conversely, if the WET COAT is applied with oil or dirt remaining on the surface, the water-repellent effect will be unstable, so surface preparation during the cleaning stage is important.
Regular construction cycle and seasonal guidelines
The key to using the GYEON three-piece set effectively is to manage the application cycle.
- IRON : Apply approximately once every three months (spring and autumn).
- BATHE+ : Use when washing your car every 2 weeks to 1 month.
- WET COAT : Use once a month as a finishing touch after washing your car.
By continuing this routine, you can remove dirt before it accumulates and keep your car looking beautiful all year round.
It is especially effective to increase the frequency of cleaning in the early spring when there is a lot of pollen and yellow dust, and in the winter when there is a lot of snow-melting agent.
Precautions when installing on glass surfaces or plastic parts
WET COAT and BATHE+ can be used on glass, but if the water repellency is too strong within the wiper movement range, it can cause a rattle noise.
Therefore, when applying to glass, it is best to spread it thinly and then lightly wipe it off after it has dried to even out the film thickness.
It is also fine to use on unpainted plastic parts, but spreading the product with a cloth rather than spraying it directly will result in a more even, natural finish.
The Significance of Scientific Maintenance
The appeal of GYEON is that it allows you to “visualize the results of your car wash.”
You can see the progress of the chemical reaction and how the water repels, making it easy to see the results of each task, leading to continued motivation.
Caring for your car based on data, rather than on intuition, is the surest way to extend the life of your car and maintain its beauty for a long time.

Summary – Maintaining quality through car washing with an understanding of chemical reactions
From sensory car wash to “managed car wash”
Traditional car washing was an intuitive process of “washing when it gets dirty,” but by using GYEON chemicals, it has evolved into a “scientifically based, controlled car wash.” It
identifies the type of dirt and uses the appropriate chemical reaction to remove and protect it.
If you make this a habit, you can reduce the frequency of heavy maintenance such as polishing and re-coating, and extend the life of the paint itself.
In other words, everyday car washing becomes “maintenance that protects your car.”
Systematic use of the GYEON three-piece set
The three steps of GYEON IRON → BATHE+ → WET COAT are independent products, but are designed to complement each other chemically.
- Iron restores the painted surface to a “clean base”
- BATHE+ creates a water-repellent base
- The WET COAT instantly fixes the “protective film”
and by repeating this cycle, dirt can be removed before it hardens, keeping the coating in a stable state.
This can also be described as a “scientific rhythm for maintaining gloss.”
Extending the life of the coating and reducing the burden of reapplication
Paint is constantly being damaged by UV rays, heat, iron particles, chemical pollution, and more.
Application of GYEON blocks these external factors at the molecular level, suppressing deterioration of the paint film.
As a result, the re-application cycle of the coating is extended, which is also economically beneficial.
Another major benefit is that if the coating is in good condition, the effort required for washing the car is reduced, and the time required for each wash can be shortened.
This is the moment when you change your thinking from “car washing = hassle” to “car washing = asset management.”
Conclusion
GYEON’s product lineup is designed to allow you to recreate professional-quality workmanship at home.
The key is to understand the role of each product and use them in the correct order.
Car washing, which utilizes chemical reactions, goes beyond simply improving the appearance of your car’s appearance; it is a form of “scientific maintenance” that keeps your paint healthy for a long time.
This accumulation of care is the greatest secret to keeping your beloved car shining like new, even after many years.

Frequently Asked Questions (FAQ)
Q1. Can beginners use GYEON products?
Yes.
The GYEON series is designed to be used at home while maintaining professional quality.
It’s a simple process that involves just spraying and rinsing, and no special equipment or skills are required.
However, because the chemicals tend to dry out easily in direct sunlight or high temperatures, it’s best to apply it in the shade or in the cooler mornings and evenings.
Q2. Can it be used on coated vehicles from other manufacturers?
Yes, it can be used.
GYEON products are adjusted to a neutral to weak acidity, so they can be applied over glass coatings and polymer-based coatings.
WET COAT in particular functions as a protective film for existing coatings and is ideal as a maintenance agent to prevent deterioration of the coating.
However, care should be taken when using it in combination with wax-based coatings, as this may cause uneven water repellency.
Q3. How often should I use iron remover?
Generally, the recommended frequency is about once every three months.
For those who drive a lot or in an environment with a lot of brake dust, a light application once a month is also effective.
Excessive use is not necessary, and it is best to check regularly until no reaction is observed (until the purple discoloration has decreased).
Q4. Is it okay if it rains after applying WET COAT?
Ideally, avoid rain or dew for three hours after application.
Allowing time for the reaction to completely stabilize will help the water-repellent properties last longer.
If you are unsure of the weather, it is a safe method to apply only BATHE+ and then add WET COAT at a later date.
Q5. Can it be used on glass or unpainted resin?
Yes.
GYEON products can be applied to glass and plastic parts.
However, the trick to applying it to glass is to apply a thin layer, avoiding the wiper movement area, and then wipe it off lightly.
Do not spray directly on plastic parts, but apply it to a cloth and spread it over to achieve a natural gloss finish.
