How to Repair Damage to the Primer?

Smooth out the burrs and raised paint edges at the scratch area. Fill in the depressions caused by the scratches. Each layer of filler must be allowed to dry before applying the next. Typically, 2-3 layers of filler are required. Sand until the filled area is roughly level. Use a flat wooden block behind the sandpaper during sanding. Unscrew the lid of the touch-up pen and insert the spray can nozzle into the touch-up pen container. Then, screw the touch-up pen body onto the corresponding threads of the spray can to complete the assembly. Continue sanding until the area becomes smooth. Finally, wax and polish the repaired paint area.

When slowing down, should you press the brake or the clutch first?

Whether to press the brake or the clutch first when slowing down depends on the vehicle speed. Press the brake first at high speeds, and press the clutch first at low speeds. Here are the detailed guidelines on whether to press the brake or the clutch first. When the car is moving at low speed: Pressing the brake directly may easily cause the engine to stall, so you can press the clutch first to prevent the engine from stopping. When the vehicle is moving at high speed: You may need to press the brake first because the engine, operating at a relatively high speed, has inertia. At this time, use a light tapping method on the brake to slow the vehicle down—remember not to brake too hard—and then press the clutch to prevent the car from stalling. Pressing the clutch first will not slow the vehicle down, and the speed may still be relatively high, keeping the car in a potentially dangerous state.

How to Solve the Problem of High Temperature Inside the Car with a Panoramic Sunroof in Summer?

Park the car in a professional underground garage, under the shade of trees, or other sheltered places. This can fundamentally avoid the car from overheating. Applying window film is equivalent to applying a layer of sunscreen to the car. This is currently the simplest and most direct method for car sun protection. If applying film is like applying sunscreen to the car, then waxing and glazing are undoubtedly like using a primer for the car. It can effectively prevent UV rays and fading of the car paint. Actually, the most sun-protective option is, of course, an underground garage. When parked outside, use a mobile car cover as a substitute. A sunshade is a more upscale option, providing heat insulation and cooling, as well as theft prevention. This method is the simplest and most effective. Currently, most car owners use this method, as it not only does not incur additional financial burden but is also easy to store.

What Methods Can Be Used to Protect Cars from Sunlight?

Parking in shade, car waxing, applying explosion-proof film, and using sunshade products. Below are relevant introductions about car sun protection: Parking in shade: When parking, try to choose underground garages or cool, ventilated areas, and avoid parking directly under the sun. Car waxing for sun protection: If there is no good parking environment, consider applying "sunscreen" to your car. Generally, car washing and waxing can provide some "sun protection" effect. If possible, consider applying glaze to your car, which adds a "protective film." This involves using a high-molecular paint care agent containing UV reflectors and a special-component curing agent to resist UV rays. Applying explosion-proof film for sun protection: Besides protecting the car paint, explosion-proof film is essential for shielding interior facilities and occupants. Commonly known as solar film, its main purpose is to "deal with" the scorching summer sunlight. Explosion-proof film blocks UV rays and has excellent heat insulation, blocking over 90% of the sun's heat, reducing air conditioning load while driving, and improving fuel efficiency. Additionally, it minimizes injuries from broken glass. It also offers one-way visibility, reduces glare, enhances personal privacy protection, and improves driving safety. Using sunshade products: Select appropriate sunshade products to reduce sunlight exposure, such as sunshades, electrostatic side window sun stickers, and sunshade nets. Sunshades have a silver side that reflects UV rays, are lightweight, foldable, and can be opened like a screen when used. Placing them on the front and rear windshields inside the car effectively reduces sunlight radiation and protects the dashboard. Sunshades come in bubble and horizontal stripe types, with the latter being slightly more effective.

What to Do When Steering Suddenly Fails?

Solutions for sudden steering failure in a car are as follows: Take emergency measures: First, immediately lift the accelerator and shift the gear lever into a lower gear; second, evenly apply the parking brake; third, when the speed significantly decreases, press the brake pedal to bring the vehicle to a gradual stop. Turn on hazard warning lights: It is essential to alert other vehicles and pedestrians on the road by turning on hazard warning lights, headlights, honking the horn, or using hand signals. Release the accelerator and reduce speed: If the power steering system fails and the steering suddenly becomes heavy, quickly release the accelerator, reduce speed, forcefully operate the steering wheel, and guide the vehicle to a suitable location. First drag and decelerate, then apply emergency braking: If the car can maintain a straight driving path and road conditions allow, avoid emergency braking. Instead, gently press the brake pedal and lightly pull the parking brake lever to bring the vehicle to a slow and steady stop. When the car is running at medium to high speeds and the steering fails without the front and rear wheels being fully aligned, emergency braking can easily cause the car to roll over. Therefore, it is safer to first drag and decelerate before applying emergency braking. Use engine braking: After steering failure occurs, do not coast in neutral or press the clutch pedal. Instead, use the engine's braking resistance to decelerate. Immediately release the accelerator pedal and shift the gear lever into a lower gear.

How to Check if the Car's Oil Level is Low Using the Dipstick?

Turn off the engine and let it sit for 15 minutes to allow the oil to drain back into the oil pan. Wipe the dipstick clean and slowly reinsert it, making sure it reaches the bottom of the oil pan. Check the oil level. If the oil level is between the upper and lower marks on the dipstick, it is normal. Otherwise, if it is above the upper limit, it indicates an issue.
