As we all know, the function of the sealing strip is to fill the gap and play a certain role in shock absorption, dust prevention, waterproof, sound insulation, etc., but the main purpose of the sealing strip on the automobile hood is to sound insulation and noise reduction. However, from the experience of Yiche's hot review, it is not really helpful to sound insulation and noise reduction to stick the sealing strip on the hood.

The valve cover sealant. Generally, the valve cover leaks oil, and the sealant or rubber pad needs to be replaced. This belongs to the normal maintenance of the vehicle. Don't worry about replacement and maintenance. But if you want to go to a regular 4S store or a second-class repair shop, don't paste it yourself.

If you apply useless sealant around the engine valve cover, it will really affect the heat dissipation of the vehicle. Although the sealing strip of the engine cover plays a significant role in the noise of the engine, it is also helpful, and it can also play a role in dust prevention. The engine is the heart of the car and the main power.

When the car left the factory, due to the consideration of engine heat dissipation, the lower guard board was not installed. Of course, many car manufacturers have also installed it now, but our engine is still often covered with dust and mud. After maintenance, due to careless oil dripping, the oil filler and screw parts will be stained with mud.

After a long time, it will become sludge and affect heat dissipation. Generally speaking, it is not necessary to apply sealant. Because the engine is baked, part of the hood is at a relatively high temperature. The original parts have been tested for safety and durability. The slope and angle of the range hood have been designed, and the installation tolerance is also required.

Long time driving, often in a high temperature environment, the service life of non original rubber parts is basically not as long as that of the original factory. The installation of the sealing strip has a fatal disadvantage. All the gaps in the car are black lines from a distance, which is not beautiful. Secondly, when washing the car, as long as it is wet, the sealing strip can easily fall off. After falling off, it will not have stickiness.

The adhesion promoter is basically ineffective. Then, every time the car is washed, in rainy or foggy weather, the moisture will affect the adhesion of the adhesive strip. The sealant with good adhesion technology or good adhesion may take a longer time. However, if you are greedy for cheap or buy inferior sealant strips, I'm afraid that the sealant strips will fall off due to the loss of adhesion after several times of use.

In fact, the author can also understand the idea that car owners want to reduce noise and sound insulation for their cars, and want to have a comfortable driving experience. However, when facing the choice of various sound insulation methods, car owners should calmly look through the advertising to see the essence. Just imagine that if the sound insulation problem of cars can be solved or suppressed through a strip of sealant.

Why should car companies spend money on sound insulation measures for doors, roof, hood and other parts? Will you spend money to improve the chassis suspension technology, use silent tires, or suggest the owner pay attention to the type of oil? There are many types of automotive sealant on the market. Whether it is safe to use depends not only on the performance, but also on the environmental protection.

As long as the glue reaches the environmental protection level, it can be used with confidence. Famous brands are more trustworthy, such as Cosmoor, which focuses on the research of automotive sealant and provides customized automotive sealant application solutions. It has a wide range of uses and can be used in new energy.

In military industry, medical treatment, aviation, shipbuilding, electronics, automobile, instrumentation, power supply, high-speed rail and other industries, when users purchase automotive sealant, in order to ensure the safety of glue, they should consider not only well-known brands, but also market reputation and price.

The market reputation mainly depends on users. The quality of brands recognized by the majority of users is not too bad. The price of car sealant with guaranteed quality may not be particularly high, but it will not be too low. When driving, the noise in the car is composed of wind noise, tire noise, and engine noise, which are transmitted to the car. The design of the car itself determines the wind resistance coefficient and wind noise.

It can not be changed at will without sealant. During driving, the heat generated by the engine will also be emitted through these gaps in the hood. The side close to the windshield will also help remove the snow on the windshield during driving. Do not apply sealant privately in winter.
