What materials are used for car polishing?

Materials used for car polishing include a polishing machine, polishing pads such as wool pads, rabbit hair pads, sponge pads, etc., polishing compounds, masking film, and paper tape. Generally, after polishing is completed, waxing, glazing, or coating is required. The steps for car polishing are as follows: 1. Wash the entire car. Use a paint cleaner with strong stain-removing power to clean the entire car. When using the cleaner, avoid causing new scratches from dust particles during polishing. 2. Sand with water sandpaper. For defects such as coarse particles, fine sandpaper marks, or flow marks on the paint surface, use 600-1000 grit water sandpaper wrapped around a small rubber block to gently sand the surface until smooth before polishing. Be careful not to sand through the paint layer. 3. Coarse and fine grinding. Use a mechanical grinder with coarse polishing compound to rough grind the marks left by the water sandpaper; then add fine polishing compound for fine grinding. 4. Polishing. Use a mechanical polisher with a mirror-finish treatment agent to remove swirl marks left by the coarse polishing compound, achieving a mirror-like polish on the paint film. 5. Manual waxing. After grinding and polishing, wipe off the polishing compound and immediately use a cotton cloth soaked in polishing wax to wipe the polished areas thoroughly. Then, use a dry cotton cloth to remove any excess wax, leaving the paint surface mirror-like and dazzlingly bright.

What are the requirements for meeting oncoming vehicles in the Subject 3 driving test?

Subject 3 requirements for meeting oncoming vehicles are as follows: 1. When meeting oncoming vehicles on roads without central isolation facilities or center lines, failing to slow down and drive on the right, or failing to maintain a safe distance from other vehicles, pedestrians, or non-motorized vehicles will result in a 100-point deduction; 2. Failing to yield when meeting oncoming vehicles is difficult will result in a 100-point deduction; 3. Poor judgment of lateral safety distance and emergency steering to avoid oncoming vehicles will result in a 100-point deduction. More details are as follows: 1. Regarding the operation during vehicle encounters, examination regulations vary by region. Some areas only require lightly tapping the brakes, some require that the right side of the vehicle body does not exceed 40 cm from the right boundary line, and some areas require the speed not to exceed 30 km/h. Specific test requirements should be consulted with the local vehicle management office or the instructor. 2. When hearing the voice prompt, the right turn signal should be activated, the situation of the vehicle behind should be observed, and the speed should be reduced with downshifting if necessary. After confirming safety, gradually move into the right lane, and when the raised part of the wiper just coincides with the right boundary line, the body is about 30 cm from the right boundary line. 3. Students can also use the right rearview mirror to judge the distance. When the current door handle position is tangent to the roadside right boundary line and the body is parallel to the boundary line, the vehicle is also about 30 cm from the right boundary line.

Do Privacy Glass Need Window Tinting?

Privacy glass does require window tinting. Here is an introduction to window tinting: 1. Besides protecting privacy, the main functions of window tinting are safety, explosion-proof, and heat insulation. 2. In case of an accident while driving, the glass can easily shatter and cause injuries. The tint film helps secure the glass fragments to prevent secondary injuries. High-quality films also provide excellent heat and UV insulation, preventing excessive temperature inside the car. Below are the steps and precautions for window tinting: 1. To avoid dust and impurities affecting the tinting effect, the car's glass must be thoroughly cleaned before applying the film. 2. Areas that might be damaged during the tinting process should be covered in advance to prevent scratches on the car paint or interior. Any accessories that might interfere with the process should also be removed beforehand. 3. After the overall preparation of the car body, the film should be cut according to the size of the glass for an initial fit. 4. The roughly cut film is then applied to the car glass. The front and rear windshields need to be heated (using a heat gun) to conform the film to the curvature of the glass, ensuring a smooth application without water marks. 5. After heating, the film will adhere closely to the glass. Further adjustments are then made, precisely cutting the film to match the shape of the glass. 6. Since window tinting is applied to the interior side of the glass, a crucial step is the installation of the film. The interior side of the glass must be cleaned thoroughly, and the film must be applied quickly and accurately to push out any water bubbles. 7. After completing all the steps, a final inspection is necessary. Check each window, especially the edges and corners, and address any bubbles immediately. 8. After the tinting is done, avoid rolling down the windows for 2-5 days. The rear windshield's defogger function should not be used, and the front windshield should not be exposed to direct air from the air conditioner. Avoid using serrated items to clean the glass. After the installation, make sure to fill out the warranty application form to ensure future after-sales service. It is recommended to return to the shop for a follow-up inspection after 3 days to address any quality issues promptly.

Emission test: ensuring the vehicle's exhaust emissions meet national standards during high-speed operation. On-road test: primarily testing the vehicle's braking system, headlights, horn, and chassis. Violation check: all traffic violations must be resolved before the inspection to pass. Vehicle inspections can be conducted up to 90 days in advance but must not be overdue.
