How to Deal with Acid Rain Stains on Car Paint?

Methods for removing acid rain from car paint are as follows: 1. Waxing: Cover the acid rain stains. This method is preferred for vehicles with minor acid rain damage, such as those with few surface spots. Apply wax with a cloth. 2. Polishing: Use polishing paste to remove the outer layer of acid rain stains, revealing a new texture. This method is suitable for vehicles with more severe acid rain damage. Carefully polish the car body using polishing tools. 3. Weak Alkaline Solution: Create a weak alkaline solution using baking soda powder, which won't harm the car and can remove stains. Dip a cloth into the solution and wipe gradually, then rinse off. 4. Weak Acid Solution like Vinegar: Vinegar won't damage the car body and can soften acid rain stains, allowing them to flow away with the vinegar. Finally, rinse with clean water. 5. Glaze and Crystal Coating Treatment: Use soft materials vibrating at high speed to allow glaze molecules to penetrate the car body, making it look smooth and shiny, thereby removing acid rain stains. 6. Complete Repainting: For car bodies severely damaged by acid rain, the only option is to go to a specialized shop for a complete repaint.

What are the evaluation criteria for straight-line driving?

Straight-line driving deduction criteria include: 1. Driving lane: Failure to reasonably choose the driving lane and speed according to traffic conditions results in a 100-point deduction. 2. Speed: Driving at an inappropriate speed results in a 100-point deduction. 3. Straight-line driving: Unstable steering control, inability to maintain the vehicle in a straight line results in a 100-point deduction. 4. Deceleration: Failure to take timely deceleration measures when the vehicle ahead brakes results in a 100-point deduction. The following are the key points for straight-line driving in Subject 3: 1. Maintain straight-line driving: First, the driver must look ahead and pay attention to both sides, select a reference point, maintain straight-line driving, adjust the direction in time, and always be aware of various traffic situations ahead to detect and handle them promptly. 2. Hold the steering wheel correctly: The driver should look far and near, holding the steering wheel correctly, and adjust the distance of vision according to the speed. At higher speeds, look farther ahead; at lower speeds, look appropriately closer; and use peripheral vision to monitor the surroundings of the vehicle.

Which is more expensive among 92, 95, and 98 octane gasoline?

98-octane gasoline is the most expensive. Gasoline is priced according to its octane rating, with 92-octane being the cheapest, 95-octane at a medium price, and 98-octane the most expensive. The fuel used in motor vehicles must match the specified octane rating indicated on the vehicle, which is usually found on the inside of the fuel tank cap. Relevant information about gasoline is as follows: 1. Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2.

How many points will be deducted for changing lanes over double yellow lines?

Changing lanes over double yellow lines will result in a 3-point deduction and a fine. Double yellow solid lines indicate that vehicles are prohibited from crossing over for overtaking, driving on the line, or making left turns, and strictly forbid vehicles from crossing. Therefore, changing lanes over double yellow lines constitutes driving against prohibited markings and will be penalized. Double yellow lines in the center are divided into yellow solid and dashed lines and double solid yellow lines. The yellow solid and dashed lines in the center, which appear at locations such as ramps and bridges where roads merge, allow vehicles on the dashed side to temporarily cross the line for overtaking or making U-turns, while vehicles on the solid side are not permitted to cross the line; otherwise, it is considered illegal. Double solid yellow lines, used to separate lanes in opposite directions, are typically painted in the middle of the road and strictly prohibit vehicles from crossing. Therefore, driving on the line, overtaking, or making U-turns are not allowed. In addition to double yellow lines, there are single yellow dashed lines, single yellow solid lines, and yellow grid lines. Single yellow dashed lines are also used to separate lanes in opposite directions and are usually marked on narrower roads. Whether single or double, as long as the line is dashed, vehicles can cross the line to overtake or make U-turns, provided it is safe to do so. Single yellow solid lines are used on roads with fewer central lanes and strictly prohibit vehicles from crossing, meaning driving on the line, overtaking, or making U-turns are not allowed. However, when yellow solid lines are marked on the roadside or curb, they indicate that vehicles are prohibited from parking, either temporarily or for extended periods. Yellow grid lines, which are grid-shaped markings, indicate areas where parking is prohibited for any reason. These markings typically appear in locations prone to congestion due to temporary parking, such as schools, institutions, residential areas, fire lanes, and intersections, reminding drivers not to park there under any circumstances.

Is it okay to drive at 120 mph during the break-in period for an automatic transmission?

It is not advisable to drive at 120 mph during the break-in period for an automatic transmission. Here are some extended details on the topic: 1. Reason: A new car is in its break-in period, and during this time, it's crucial to control the driving speed, avoiding excessively high speeds. The recommended speed range is 50~80 km/h. The surfaces of various components in a new car are still relatively rough, with potential processing and assembly deviations and hidden issues. High-speed driving can exacerbate wear between parts or lead to safety incidents. 2. Break-in period precautions: When starting cold, allow the water temperature to warm up to above 40°C before moving off. When starting, apply the clutch and accelerator gently, avoiding revving the engine in neutral. Start in a low gear and gradually shift to higher gears, driving progressively. Avoid driving in a single gear for extended periods during the break-in period. Also, be sure to avoid low-gear high-speed or high-gear low-speed scenarios.
