The reason why the car paint feels gritty when touched by hand is that there are pinholes or signs of sanding on the car's paint surface. Here are the relevant details: 1. Composition: The car's paint surface consists of four layers, from the inside to the outside: the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. If you go to some unprofessional paint repair shops, the paint surface may become rough. 2. Hazards of polishing: Frequent polishing can reduce the thickness of the clear coat and accelerate the aging process of the car's paint surface, which may also lead to a dull appearance of the paint surface.

How much can be deducted from taxes when buying a car?

The vehicle purchase tax is calculated based on the tax-exclusive price, with a tax rate of 10%. The tax-exclusive price refers to the total price and additional fees paid by the taxpayer to the dealer when purchasing the car, excluding the value-added tax (VAT). Below are the relevant details: 1. Standard: For general taxpayers purchasing a car, the unified invoice for motor vehicle sales cannot be used for tax deduction. It must be replaced with a special VAT invoice and certified before it can be deducted. Fixed assets purchased after January 1, 2009, can be used to deduct VAT (provided the seller issues a VAT invoice). 2. Unified Invoice: If the purchased car is not subject to consumption tax and is used for production or business operations, it is eligible for tax deduction. The buyer should request the dealer to issue a special VAT invoice (the dealer should be a general taxpayer, issuing a 17% special VAT invoice), which can then be certified and deducted at the national tax bureau.

What is the Transmission Self-Learning Function?

Transmission self-learning function refers to the capability of an automatic transmission to adapt to the driver's driving habits. The most important and challenging aspect of this function is the adjustment of its own shifting parameters. Below are specific introductions to different types of transmissions: 1. CVT: CVT stands for Continuously Variable Transmission. Its advantages include fuel efficiency, affordable maintenance, and smooth operation, but it offers weaker acceleration sensation and has limited capacity for handling high torque from powerful engines. 2. AT: AT stands for Automatic Transmission. Its benefits lie in ease of operation and relaxed driving experience, as the transmission automatically selects the most suitable gear based on vehicle speed and feedback from the onboard computer. However, it comes with higher maintenance costs and fuel consumption. 3. DCT/DSG: Both DCT (Dual Clutch Transmission) and DSG (Direct-Shift Gearbox) are types of dual-clutch transmissions. They feature fast shifting speeds, high efficiency, and low fuel consumption. However, they require high manufacturing precision, resulting in higher costs, and may offer less comfort.

What are the items included in the first maintenance of a truck?

The following are the items included in the first maintenance of a truck: 1. Oil and oil filter replacement: Since the period before the first maintenance is the running-in period of the vehicle, the gradually running-in engine will continuously mix mechanical impurities such as dust, metal wear, and carbon deposits into the oil during operation. This is why it is said that you should not drive at high speeds during the running-in period, as the oil contains too many impurities during this time. 2. Tightening nuts: During the first maintenance of a new truck, the nuts in various parts of the truck should be checked. Considering the shaping period of the new truck, some screws may not be particularly tight. During the first maintenance, all screws will be tightened according to the specified torque. 3. Chassis inspection: During the first maintenance of a new truck, the vehicle will be lifted to check the chassis for any scratches, underbody damage, corrosion, or oil leaks.

What are the installation size specifications for parking space wheel stoppers?

The installation dimensions for parking space wheel stoppers are 500mm×160mm×105mm, with a length of approximately 7m. Below is an introduction to wheel stoppers: 1. Introduction: Also known as wheel stoppers, barrier gates are specialized equipment used to restrict vehicle movement at road entrances and exits. They are widely applied at highway toll stations and parking lots to manage vehicle access. 2. Function: Electric barrier gates can be operated individually via wireless remote control to raise and lower the barrier arm, or they can be automatically managed through a parking lot management system (i.e., an IC card swipe management system). 3. Types: These include integrated barrier gate mechanisms, clutch devices, intelligent anti-lift functions, obstacle detection and return mechanisms, heating functions (ensuring operation in temperatures as low as -40 degrees Celsius), ventilation cooling systems (to promptly reduce motor temperature), automatic clutch devices, anti-collision and arm release mechanisms, etc. The speed of raising and lowering the barrier arm varies from 0.8 seconds to 6 seconds.

What is the vehicle range for a C1 driver's license?

The following is the vehicle range for a C1 driver's license: 1. Sedans: Generally, the total weight of small sedans does not exceed 4.5 tons, the seating capacity is usually 5 people, and most vehicles with a length not exceeding 6 meters can be driven with a C1 license. 2. SUVs: SUV models are relatively heavier but generally do not exceed 4.5 tons, typically available in 5-seat or 7-seat configurations, so SUVs can also be driven with a C1 license. 3. MPVs: Most MPVs have 7 seats but do not exceed 9 seats, with length and weight falling within the category of small cars. 4. Vans: Larger vans may exceed 9 seats or have a length exceeding 6 meters. Such large vans cannot be driven with a C1 license. 5. Small trucks: Small trucks with a total weight not exceeding 4.5 tons and a length not exceeding 6 meters (including so-called agricultural vehicles).
