Owners of used cars often face the problem of burnout and loss of color of the cabin elements. The sun’s ultraviolet rays and temperature changes turn the once deep black color into a dull gray, spoiling the overall impression of the interior. Plastic restorer Shima It has proven itself as an effective solution for restoring color saturation and protecting surfaces from further degradation. This product is designed specifically to combat the oxidation of polymeric materials, returning them to their factory appearance.
Unlike cheap polishes that create a greasy shine, the compositions of the series Shima They are aimed at deep penetration into the structure of the material. They don’t just mask defects, they repair molecular bonds on the surface. The use of high-quality chemistry allows you to extend the service life of parts and maintain the aesthetic appeal of the cabin for many years.
The recovery process does not require complex equipment or specialized skills. It is enough to know the basic rules of surface preparation and application technology to get a result comparable to the work of a detaching studio. In this article, we will analyze in detail the composition, features of application and nuances that will help you achieve the perfect matte finish.
Features of the composition and the principle of operation
The effectiveness of any restorer depends on its chemical formula. Products Shima It is based on a combination of silicone polymers, solvents and special UV filters. Solvents provide delivery of active substances deep into the porous plastic, where the process of color regeneration occurs. After the evaporation of volatile fractions, a strong protective film remains on the surface.
The key component is ultraviolet stabilizer. It blocks the damaging effects of the sun, which is the main cause of burnout. Without this component, any reducing agent will only have a temporary cosmetic effect. The formula is designed in such a way as not to overdry the material, maintaining its elasticity and preventing the appearance of microcracks.
⚠️ Note: The composition may contain aggressive solvents. Avoid getting products on leather seats, textiles or lacquered wooden inserts, as this can cause them to change their color or structure.
It is important to note that Shima It's not paint. It does not physically paint the scratches, but chemically restores the color of the burned layer. If there is deep mechanical damage or rubbing to the base, the restorer will only slightly hide the defect, but will not eliminate it completely. For such cases, pre-surfacing or the use of denser coatings is required.
Can I use Shima on rubber mats?
The chemical composition is safe for most types of automotive rubber. However, on very porous or old rubber, a temporary change in shade may be observed. It is recommended to test on an inconspicuous area before full mat treatment.
Preparation of surface for treatment
The quality of the final result depends on 80% of the preparation. Applying the restorer to a dirty or fat-free surface will lead to an uneven distribution of the composition and rapid washing away of the protective layer. The first step should always be deep-cleaning salon.
Use a special plastic cleaner or a universal degreasing agent. Ordinary water or soapy solution can leave a fatty film that will block the penetration of active components. Shima. Carefully walk with a soft bristling brush on all relief areas to wash the dirt from the pores.
- 🧹 Carefully vacuum the cabin, removing dust from all cracks and ducts.
- 🧽 Wash the surfaces with water with auto shampoo to remove the underlying dirt.
- 🧪 Degrease the plastic with a special cleaner (degrimer) or isopropyl alcohol.
- 💨 Dry the surfaces completely with compressed air or microfiber before application.
Pay special attention to hard-to-reach places around buttons and pens. Remains of old polish or skin conditioner must also be removed. If there is a sticky layer on the surface, then the preparation is not carried out qualitatively enough, and the cleaning procedure must be repeated. Only on a perfectly clean basis the restorer will lie flat.
☑️ Checklist of preparations
Shima restorer technology
Process of application of the instrument Shima It is quite simple, but requires accuracy and dosage. Apply the composition is best at ambient temperatures from +15 to +25 degrees Celsius. In a too cold or hot room, chemical reactions can occur incorrectly, which will affect the quality of the coating.
Shake the can or bottle for 10-15 seconds to evenly mix the components. Apply a small amount of funds to a microfiber applicator or foam sponge. Do not pour liquid directly onto the plastic, especially if it is vertically positioned to avoid leaks that are difficult to remove.
With uniform circular movements, rub the composition to the surface. Move from one side of the part to the other, without missing sections. Exposition time This is usually 3 to 5 minutes, during which the active substances penetrate the material structure. After that, it is necessary to polish the surface with dry clean rags until a matte effect is obtained.
| Parameter | Meaning/Recommendation | Note |
|---|---|---|
| Expenditure | 10-15 ml per 1 sq.m. | Depends on the porosity of plastic |
| Drying time | 5-10 minutes | Before the stickiness disappears |
| Temperature of application | +15...+25 °C | Avoid direct sunlight |
| Term of protection | Up to 3 months. | Provided that the wash is not aggressive chemistry |
If after polishing there is a greasy shine, then you have applied too much money. In this case, simply wipe the surface again with a dry wipe. To achieve maximum effect and durability, the procedure can be repeated after 24 hours, applying a second, fixing layer.
Apply the restorer with the engine turned off and the cold cabin. On hot plastic, the remedy can dry too quickly, leaving divorces that are difficult to polish.
Comparison with Competitors and Analogues
There are many products on the market for car care, and Shima It occupies its niche among professional means. Unlike supermarket aerosols, which are often excessive in glycerol and stickiness, this product is focused on long-term results. Competitors often offer either purely decorative effect or protection, but rarely immediately.
The main advantage is the balance between cost and volume. Professional concentrates can be more expensive, but require breeding, while Shima ready to use immediately. Cheap analogues are often washed away after the first wash or even just from touching clothes, leaving divorces.
- 🏆 Resistance: It withstands several contacts with wet fabric, unlike wax polishes.
- 🎨 Appearance: It gives a deep matte hue, not the effect of "cheap gloss".
- 🛡️ Defense: It contains powerful UV filters that block up to 98% of radiation.
It is worth noting that a very old “grey” plastic that has lost its structure completely may require more radical interventions, such as painting or retweeting. But in 90% of cases, when the plastic is burned, Shima restorer is able to return it almost factory-likeBy hiding a grid of small cracks.
Common mistakes in the use of
Even with a quality tool, you can get a bad result if you break the technology. The most common mistake is to apply the funds to insufficiently cleaned plastic. Dust and dirt are mixed with the restorer, forming an abrasive gruel that, when polished, can leave micro-scratches.
Another common problem is the use of dirty or fuzzy rags. Worm can get stuck in the pores of textured plastic, and it will be extremely difficult to pull it out of there. In addition, old rags that have previously wiped wheels or engines may contain residues of oil or gasoline.
⚠️ Attention: Do not use the product Shima on the steering wheel and pedals! The surfaces treated with these compositions become slippery, which can lead to an emergency situation when driving a car.
Do not attempt to speed up the drying process with a hair dryer or a directed stream of hot air. Dramatic heating can lead to swelling of the coating or uneven distribution of polymers. Let the chemistry work in natural conditions, it guarantees the manufacturer's declared resistance.
Care for treated surfaces
Once you have done the restoration, it is important to properly care for the salon to maintain the effect. Processed plastic becomes less susceptible to dust, but regular cleaning is still necessary. Use soft microfiber wipes to remove dust from torpedoes and door maps.
When washing your car, try not to pour water under high pressure directly on the treated interior elements, unless there is an urgent need for this. Although the coating is moisture resistant, the constant pressure of the jet can shorten its service life. For wiping, use special sprays for quick care (detailer spray), do not contain aggressive solvents.
Regularity of re-treatment depends on the operating conditions of the car. If the machine is in the sun or is often used in hot climates, it is recommended to update the layer every 2-3 months. For garage cars or with moderate use, one application can be enough for six months or more.
Proper care of recycled plastic extends the effect twice. Avoid alcohol-containing glass cleaners splashing on the torpedo.
Frequently Asked Questions (FAQ)
Can I put Shima on multimedia screens?
No, it's not recommended. The screens have a special oleophobic coating that the aggressive components of the restorer can damage. For screens, use only specialized electronics chemistry.
How much does the product dry before polishing?
The optimal waiting time is 3-5 minutes before the appearance of mild mattress. If you hold the product for longer than 10-15 minutes, it can freeze in the pores, and polish it to the ideal will be more difficult.
Will it remove deep scratches?
The restorer masks small scratches by filling the pores and restoring color. Deep damage, where the integrity of the material is violated, it will not remove. This requires plastic repair or painting.
Is the smell of a health product safe?
The product has a characteristic chemical odor that weathers after drying (after 15-20 minutes). During application, it is recommended to keep the windows open for airing the cabin.
