White spots on car paint are mainly caused by acidic substances in rainwater mixing with iron particles in the air, which then settle on the paint surface. Below are the treatment methods. Using Iron Remover: Apply a professional iron remover evenly on the white rust spots. The rust spots will dissolve, and when the color turns purple, wipe with a sponge and rinse with clean water. Repeat if necessary. Using Clay Bar: Clay bars have a polishing effect and can remove stubborn stains on the car surface. For rust spots, wet the car body first, then use the softened clay bar to gently rub the affected areas in even motions, keeping the surface moist.

What Insurance Do You Need to Buy for a Car?

Generally, car insurance requires the purchase of compulsory traffic insurance, vehicle damage insurance, and third-party liability insurance. Insurance should be selected based on your actual situation. Compulsory Traffic Insurance: As one of the legally mandated insurances, compulsory traffic insurance stipulates that if a third party suffers losses, regardless of fault or the need for compensation, the insurance company must pay a certain amount to the affected party. However, in cases of at-fault accidents, the cost may increase by 10%-30% based on the year or frequency of occurrence. Vehicle Damage Insurance: Vehicle damage insurance is also typically a must-have. For everyday issues like scratches, repair costs can be reimbursed by the insurance company. Especially in accidents where the responsible party cannot be identified, the insurance company will cover 70% of the costs. However, compensation under vehicle damage insurance is calculated based on the car's usage time and depreciation, with an annual depreciation rate usually set at 7.2%. Third-Party Liability Insurance: Fully known as third-party liability insurance, it is a type of liability insurance. It covers the financial compensation that the insured must legally or conventionally bear due to their own fault or negligence causing personal injury or property damage to a third party.

What is the normal annual mileage for a private car?

It is normal for a private car to run 10,000 to 20,000 kilometers a year. It should be noted that during the use of the car, the replacement of vulnerable parts such as tires, timing belts, brake pads, spark plugs, and various car fluids should be carried out according to the maintenance manual provided with the car. More information is as follows: 1. Theoretically, the service life of a car can be divided into three types: technical service life, economic service life, and reasonable service life. The technical service life is the physical life of the car, that is, the total time from when the car is put into use as new until its technical condition deteriorates severely and it is no longer usable and must be scrapped. 2. From the perspective of economic service life, the manufacturing cost of the car, the cost of use and maintenance, management fees, current depreciation, and changes in market prices are all important factors in determining how long it is cost-effective to keep a car.

How Long Is the Validity Period of the Driving Skills Test Certificate?

The validity period of the driving skills test certificate is three years. Applicants must complete the subject two and subject three tests within this period. If the tests are not completed within the validity period, the passed subjects will be invalidated. Article 32 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" stipulates that for first-time applicants or those applying to add a permitted vehicle type, the vehicle management office must issue the driving skills test certificate within one day after passing the subject one test. If the driving skills test certificate is lost, it can be reissued through the driving school. If the written test admission ticket is lost, it can only be reprinted. The reprinting methods include: Previously saved backups, including scanned copies, webpage screenshots, saved webpage files, photos, etc., are valid as long as the information is clear; Log in to the local personnel examination website again, enter the printing page, and reprint; If none of the above methods can solve the problem, contact the examination organizing unit, usually the local personnel bureau, to inquire about the situation and arrange for a separate print.

Is Fogging Inside New Car Headlights Normal?

External headlight fogging can be categorized into two scenarios based on severity: First, mild condensation inside the headlight without water droplet formation on the surface; Second, heavy condensation with visible water droplets on the headlight surface. Mild condensation is a normal physical phenomenon. However, if heavy condensation occurs after ruling out external factors, the headlight assembly requires replacement. Detailed explanations follow: 1. Causes of mild headlight condensation: Modern vehicle headlights feature open-ventilation designs, making mild condensation a normal physical phenomenon. When temperatures drop, warm moisture accumulates in the fastest-cooling areas of the headlight, condensing into water. Condensation dissipation depends on environmental conditions (temperature, humidity) and vehicle operation. If fogging disappears quickly under high ambient temperatures, replacement isn't necessary. Under the aforementioned conditions, continuous 30-minute headlight operation eliminates internal fogging when external humidity is low. 2. Causes of heavy headlight condensation: First inspect all lens covers, ventilation components, plugs, and sockets for proper positioning; Verify ventilation component permeability; Check for cracks in housing/lens components; Identify any aftermarket modifications; Determine if the vehicle has been stationary in waterlogged areas. If external factors are eliminated, the headlight assembly must be replaced.

Can You Cover a Car with a Car Cover in Summer?

You can cover a car with a car cover in summer, but you need to avoid direct sunlight and ensure the car is cool before covering it. Avoid direct sunlight: Make sure to park the car in a place where it is not exposed to direct sunlight. Otherwise, the cover may cause the car's temperature to rise abnormally, which could affect the paint and even the interior. Cover the car when it is cool: Try to ensure the engine is in a cool state. Do not cover the car immediately after driving when the engine is still hot. Since the car cover is relatively enclosed and not breathable or waterproof, it may cause engine damage due to difficulty in dissipating heat. Covering the car in summer not only provides some sun protection and dust prevention but also avoids harmful substances like bird droppings and insect residue from sticking to the paint, offering many benefits. However, some car owners feel that covering the car in summer is like trapping it, making the interior stuffier. If the cover feels non-breathable, you can choose a car cover with a support frame. This not only avoids friction between the fabric and the paint but also uses air for insulation, improving air circulation to some extent.
