Does a Car Need Waxing? Is Waxing Good?

Introduction to the Pros and Cons of Car Waxing: I. Pros: 1. Polishing Effect: Polishing is the most basic function of car wax. After waxing, the vehicle's surface brightness can be improved, restoring the body's original luster. 2. Waterproof and Acid Rain Protection: Due to the protection of car wax, the amount of water droplets adhering to the car body is significantly reduced. 3. Heat Resistance: Cars are exposed to high temperatures and sunlight year-round, which can cause the paint to age and fade. The film formed by waxing effectively reflects light, preventing incident light from aging and fading the paint or base coat. 4. Anti-Static Effect: Static electricity in cars comes from interior fabric and friction between airborne dust and the car body during driving. Static electricity often causes many inconveniences. Car wax effectively blocks dust from the car body, reducing static electricity generation. 5. UV Protection: The UV protection effect of car wax works in parallel with its heat resistance. Due to the nature of UV light, it easily refracts into the paint surface. UV-protective car wax takes this characteristic into full consideration, minimizing damage to the car's surface. 6. Polishing and Buffing Effect: When shallow scratches appear on the paint surface, polishing wax can be used without harming the paint. II. Cons: 1. Product Damage: There are many types of car waxes on the market with varying performance, effects, and results. Improper selection or use of low-quality wax can damage the car paint. 2. Paint Surface Wear: Due to the polishing effect, improper operation or repeated polishing can easily wear the paint surface. 3. Dirt Adhesion: Under high temperatures and prolonged engine operation, the wax can melt and easily adhere to dust and stains.

What is Protech Tire?

Protech is a product of Viking Tires, a sub-brand under Continental Tires. Viking Tires was established in Norway in 1920 and acquired by German company Continental in the 1990s. While Continental Tires has been present in China for a long time, the Nordic Viking brand only entered the Chinese market in recent years. Viking Tires are produced at Continental's factory in Hefei and its facility in Malaysia, meaning they share the same production line as Continental Tires. Nordic Viking automotive tires are specifically introduced by Continental for Chinese road conditions. The domestic market offers four tread patterns: CT5, PT5, HT, and AT. Most are produced at the Hefei Continental factory, while SUV tires are imported from Malaysia. Viking Tires began manufacturing tires in 1931 as a wholly Norwegian-owned company, holding over 50% market share in Norway. In 1992, it became fully owned by Continental Group and supplies original equipment for brands like Volkswagen, Opel, Ford, and Volvo. Protech utilizes computer-optimized tread block circular notches to coordinate ground contact edges, suppressing noise generation and propagation, effectively reducing tire noise levels. Protech features longitudinal groove conical designs to minimize stone retention during driving. Its 3D design facilitates automatic stone ejection, protecting the tire from stone drilling damage. Protech employs continuous center ribs with dual-rib reinforcement in outer zones. Interlocking rubber pillars embedded in lateral grooves significantly enhance tread rigidity, delivering responsive handling performance. Viking Tire maintenance methods: Enhance awareness of tire safety through regular inspections. Periodically correct wheel balance as imbalance causes high-frequency oscillations during high-speed driving, leading to irregular tire wear. Implement regular tire rotation every 5,000 km to ensure even wear across all tires on the vehicle. Daily usage precautions for Viking Tires: Routinely check for surface cracks or deformations. As tread grooves gradually shallow with wear, completely worn patterns lose water drainage and anti-skid capabilities, severely compromising vehicle performance. Small cracks may become high-speed blowout hazards. Remove trapped stones from grooves promptly. Park on level surfaces whenever possible. Avoid parking on surfaces with thick, sharp, or pointed stones. Keep vehicles away from petroleum products, acids, or other materials causing rubber deterioration. Avoid turning the steering wheel when parked to prevent accelerated tire wear. Never use water for cooling. During hot weather or high-speed driving, tires may overheat with increased pressure. Allow natural cooling when parked—never deflate or splash water, as this causes abnormal tread rubber aging. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear from tire-ground dragging.

Will changing the color of fog lights result in penalty points?

Changing the color of fog lights will not result in penalty points. The main car modification projects are as follows: Exterior; Exterior modifications have always held significant importance. Common exterior modifications include stickers, body paint, emblems, front and rear bumpers, body kits, high rear wings, vented engine hoods, window rain guards, HID xenon headlights, headlight decorative panels, front and rear perspective mirrors, and lowering the suspension. Engine; Like the heart of a person, the engine is the heart of a car, making it the most crucial part of the vehicle. Modifying it is also the most complicated. The primary goal of engine modifications is to increase its power output. Methods include enlarging the cylinder bore, increasing the compression ratio, adding more valves, converting from naturally aspirated to turbocharged, etc. However, it is essential to note that engine modifications are quite dangerous. A slight mistake can damage the engine or even cause severe safety accidents. Intake system; The engine requires a large amount of air to operate. Air entering the engine first passes through the air filter, the most critical component of the intake system. Most factory-installed filters are disposable paper filters. Aftermarket products are made from special chemical fibers, with the primary advantage of filtering air while increasing the airflow and velocity into the combustion chamber by over 30%. This results in more complete fuel combustion, higher efficiency, and naturally better engine performance. Interior modifications mainly include the following: 1. Installing an anti-theft system: Security is a top concern for car owners, so new cars are often equipped with anti-theft devices. Common anti-theft devices on the market include alarms, central locking systems, gear locks, and steering wheel locks. An alarm in anti-theft mode can lock the engine, making it impossible to start the car even with the original key. It can also connect to the central locking system of all four doors, making it convenient to open and close doors. It features an audible alarm function and can be switched to silent mode to avoid disturbing others, making it popular among car owners. 2. Laying floor mats and carpets: The area under car seats is usually covered with a carpet-like material installed by the manufacturer. Once dirt or stains get on it, they are difficult to clean. Therefore, most people lay a waterproof, easy-to-clean protective layer—floor mats—under the seats after purchasing a new car. Floor mats are typically made of 3mm thick rubber and come in colors like gray, beige, and black. The quality of installation is also crucial; poorly installed mats may have edges that lift or uneven surfaces, making them uncomfortable. 3. Applying explosion-proof film: There are many types of explosion-proof films on the market. When choosing, opt for imported films with warranty cards. Besides the quality of the film itself, the installation process is also important. First, the film must be applied indoors, and the glass must be thoroughly cleaned of any dirt or impurities using water spray and scrapers before application. Second, the film must be applied in one go without repeated peeling and reapplication. If bubbles or wrinkles appear after application, the film must be replaced and reapplied.
