When there are dense small dents on a painted surface, traditional sheet metal repair techniques can be used to resolve the issue, or alternatively, paintless dent repair (PDR) technology can be employed. Traditional Sheet Metal Repair: Sheet metal repair involves fixing the deformed parts of a car's metal body. For example, if the car's outer shell has been dented, sheet metal work can restore it to its original shape. Then, by applying specialized paint, the deformed metal surface can be restored to match the undamaged areas, making it look as good as new. Paintless Dent Repair (PDR): Paintless dent repair, often referred to as paintless car dent removal, is based on optical and mechanical principles. It uses leverage to gradually restore dents of varying depths back to their original condition (similar to a factory reset on a phone).

As a veteran mechanic with over a decade of experience in auto repair shops, we call these small pockmarks on car paint 'orange peel effect.' The main causes are either dust falling onto the paint surface in an unclean spraying environment or improper thinner ratio preventing the paint from leveling smoothly. Our treatment process involves first sanding off the old paint from the entire vehicle, then using infrared heating lamps while applying body filler to fill the pits. For repainting, choose a dust-free baking room and adjust the atomization pressure to 2.5Bar for even coverage. Remember not to wash the car within three days after painting, otherwise moisture seeping into the paint layer will cause bubbles. When parking normally, try to avoid parking under trees as resin drips are most damaging to paint.

Our auto detailing shop often handles this kind of job - those annoying paint surface pits. Nine times out of ten, this issue is caused by dust contamination during painting or the clear coat curing too quickly. Our treatment process has three steps: deep pits are leveled with specialized filler paste, while shallow pits can be resolved with simple polishing. When repainting, humidity control in the paint booth is crucial - if it exceeds 60%, we must turn on the dehumidifier. After completion, we recommend monthly crystal coating applications to create a protective layer against small stone chips. We had a customer who ignored our advice and parked near a construction site - the pits reappeared within six months, making it money wasted.

How long after new car registration can the license plate be changed?

New car license plates can be changed after three years of registration. The original license plate can be canceled, and a new plate can be applied for. Vehicle license plates can be canceled, but the vehicle for which the cancellation is being processed must have been registered under the owner's name for more than three years. License plate reselection stage: You can choose a new license plate. After successfully selecting a number, the number is generally reserved for three working days. During these three days, the user cannot choose a license plate number online again. However, if registration is not completed within three days, the license plate number will be canceled, and you can then choose a new preferred license plate number online. Already registered with a license plate: You can choose to transfer the car to the owner's registered residence or temporary residence, or transfer the car to someone else. However, each transfer is equivalent to a transaction, which will have a certain impact on the car's resale value.

Does China V Have a Particulate Filter?

China V era did not have particulate filters. Under the China V standard, the vast majority of companies were able to complete the design, production, and manufacturing of engines using existing technologies to meet the emission requirements at that time. With the exception of a very few models, almost all China VI models are equipped with particulate filters. After the China VI standard was released, automakers found it nearly impossible to meet the China VI standard without changing design direction, R&D investment, or performance. Therefore, most models compliant with the China VI standard are equipped with particulate filters. Methods to check for a particulate filter: Refer to the and to see if there is a particulate filter function. Additionally, you can carefully check the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator; check the label on the oil cap—if it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter; look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section—if so, that is the particulate filter.

What are the consequences of using 2T oil in a four-stroke vehicle?

Adding two-stroke oil to a four-stroke motorcycle can damage the engine. Two-stroke motorcycle oil is designed for mixed combustion, meaning the oil is blended with gasoline, lubricates engine components, and then burns along with the fuel. Two-stroke engine: In two-stroke motorcycles, the oil must participate in combustion to lubricate components such as the cylinder, piston, and piston rings. If four-stroke oil is used, excessive carbon deposits may form on the cylinder head, piston, exhaust port, and exhaust pipe, negatively affecting engine operation and lubrication, and potentially increasing wear. Four-stroke engine: The working principle of a four-stroke diesel engine is the same as that of a four-stroke gasoline engine, consisting of four strokes: intake, compression, power, and exhaust. The difference is that a diesel engine intakes pure air during the intake stroke. Near the top dead center of the compression stroke, the fuel injector sprays diesel into the combustion chamber. Since the temperature inside the cylinder at this point far exceeds the auto-ignition temperature of diesel, the injected diesel undergoes a brief ignition delay before spontaneously igniting and combusting, generating power.

What to Do If Your License Plate Falls Off While Driving?

After losing your license plate, the first thing you should do is call the police, then file a report at the local police station in your jurisdiction. This prevents your plate from being used illegally by others, who might commit violations in your name. Applying for a replacement plate is straightforward—simply visit the vehicle management office without needing to report to the public security bureau. Here are the key points to note when replacing your license plate: In addition to your vehicle registration certificate and personal ID, make sure to bring your motor vehicle registration certificate if you have one. For company vehicles, you'll also need the organization code certificate. First, fill out a license plate replacement application form at the vehicle management office. For company vehicles, the form must be stamped with the company seal before submission. The office will then provide you with a police receipt and a temporary license plate. The temporary plate should be prominently displayed on the front windshield for police inspection. Using a temporary plate does not affect your annual vehicle inspection. If only one plate is lost, you must surrender the remaining old plate when applying for a replacement. After 30 working days, you can collect your new license plate from the vehicle management office. If the new plate has the same number as the old one, your original vehicle registration certificate remains valid and does not need to be replaced.

Does Greater Torque Mean More Power?

Theoretically, under the condition of constant engine power, torque is inversely proportional to engine speed. The faster the speed, the smaller the torque, and vice versa. However, it is not accurate to say that the greater the engine torque, the faster the vehicle accelerates. It can only be said that greater engine torque contributes to improved acceleration performance. Engine Overview: Torque is a special moment that causes an object to rotate. Engine torque refers to the moment output from the crankshaft end of the engine. Under fixed power conditions, it is inversely proportional to engine speed—the faster the speed, the smaller the torque, and vice versa. Role of Torque: Torque reflects the load capacity of a vehicle within a certain range. External torque is called torsion or external couple moment, while internal torque is called internal couple moment or simply torque. Different Applications: For family cars, greater torque means better acceleration; for off-road vehicles, greater torque allows for steeper climbing angles; for trucks, greater torque enables the vehicle to pull heavier loads. Generally, the greater the torque, the better the vehicle performs. This also applies during driving—under the same displacement conditions, greater torque indicates a better engine.

Does the Brixton 250 from Wangjiang have many minor issues?

Overall, it has relatively few faults. Brixton is a motorcycle brand originating from Austria. While it is positioned as a European brand, its production line is located in Taizhou, Zhejiang. Without the brand logo, it appears to be a domestic motorcycle, but with the "Brixton" branding, it transforms into a European motorcycle. Origin of Brixton: In fact, the Brixton brand originally emerged in Europe. The core members of its vehicle design and R&D team were a group of local motorcycle enthusiasts. Unfortunately, while they had great ideas, they lacked the capability for mass production. Consequently, the brand moved to China, known as a "manufacturing powerhouse," and established its first motorcycle production factory in Taizhou. Since then, Brixton motorcycles have appeared in the public eye. Features of Brixton: Brixton focuses on small-displacement, entry-level scooters. For example, the Brixton Lanka 150 adopts the "lambretta" appearance design, making the bike look compact and cute. On the other hand, the Brixton Jizhou ADV150 has a more touring-style design, giving off a bold and cool visual impression, catering to diverse consumer aesthetic preferences.
