4S shops do not apply film to the entire car. The 'full car film' mentioned by 4S shops refers to applying film to all the car's windows, including the front windshield, rear windshield, and the windows of the four doors, but it does not include the car body and rearview mirrors. The benefits of car window film are as follows: 1. Heat insulation and sun protection: The film can effectively block a large amount of heat generated by infrared rays. 2. UV protection: Medium and long-wave ultraviolet rays can penetrate thick glass, but applying heat-insulating film can block 99% of UV rays, preventing skin damage and reducing the aging of car interiors. 3. Safety and anti-explosion: The base layer of the film is made of polyester, which has strong tear resistance and anti-penetration properties, preventing secondary injuries to passengers in case of accidental glass breakage. 4. Reduced air conditioning energy consumption: Applying heat-insulating film can compensate for some loss of air conditioning cooling capacity, helping to prevent excessive interior temperatures and thus saving fuel and reducing air conditioning energy consumption to some extent. 5. Anti-glare: It keeps the eyes comfortable and reduces accidents caused by glare.

What Kind of Paint is Used for Cars?

Here is a detailed introduction to automotive paint: 1. Standard Paint: This type of paint usually comes in solid colors like black, white, or red. Advantages: Low cost, affordable. Disadvantages: The paint is relatively soft, prone to scratches, and may oxidize and discolor over time. 2. Metallic Paint: Metallic paint is essentially standard paint with added metal particles. It enhances the car's color, making it appear more vibrant and glossy under strong light, with visible metal particles. Advantages: Rich color, high strength (harder paint), less prone to minor scratches, and resistant to oxidation and discoloration. Disadvantages: Slightly more expensive. 3. Pearl Paint: This paint is based on standard paint but includes both metal particles and mica particles. Advantages: Due to the addition of metal and mica particles, the car body exhibits different colors from various angles, creating a layered effect. It is harder than the previous two types of paint, more scratch-resistant, and oxidation-resistant. Disadvantages: Expensive, difficult to repair, and prone to color discrepancies.

What Are the Reasons for Slow Car Charging?

Here is a detailed explanation of the reasons for slow car charging: 1. The charging gun is not properly inserted: In this case, the charging port indicator will show a flashing yellow light, indicating low charging power. At this time, you should check whether the charging gun is properly inserted. 2. The charging gun is overheated: When the charging power is displayed as low or 0, it may be due to the overheating of the charging gun. In this case, touching the gun will feel hot. 3. The battery temperature is too low: A snowflake symbol on the electric vehicle battery indicates that the battery temperature is too low. Similar warnings may appear in extremely cold weather in some regions during winter. 4. The battery charge is high: When the battery charge is close to the charging set value, the charging power decreases compared to the initial charging stage, as the battery charge is already high. 5. Charging equipment failure: In super charging stations, multiple vehicles may experience reduced charging power regardless of their battery charge level.
