As we all know, the role of the seal is to fill the gap, to play a certain role of shock absorption, dust, waterproof, sound insulation, but the main use of the seal on the hood of the car is to sound insulation and noise reduction, but from the experience of easy car heat evaluation, in the hood of the seal strip is actually of little help to sound insulation and noise reduction.

Valve chamber cover sealant, in general, valve chamber cover oil leakage phenomenon, then need to replace the sealant or rubber pad, which belongs to the normal maintenance of vehicles, do not worry about replacement maintenance, but if you want to go to the regular 4S shop or second rate repair shop, do not stick yourself.

If the engine valve chamber cover is coated with useless sealant around, it will indeed affect the heat dissipation of the vehicle. Although the hood seal plays a large role in the noise of the engine, it is also helpful, and can also play the role of dust prevention. The engine is the heart of the car, the main power.

When the car leaves the factory, for the consideration of engine heat dissipation, there is no installation of the lower guard plate. Of course, many automobile manufacturers have installed it now, but our engine is still often covered with dust and mud. After maintenance, due to careless dripping of oil, the oil injection port and screw parts will be stained with mud.

Generally speaking, there is no need to apply sealant. Because the engine is baked, a part of the hood is at a relatively high temperature. The original parts have been tested for safety and durability.

Driving for a long time, often in a high temperature environment, the service life of the non-original rubber parts is basically not as good as the original factory, the installation of the seal has a fatal disadvantage, all the gaps in the car far look black line, not beautiful, secondly, when washing the car, as long as it is wet, the seal is easy to fall off, fall off, there will be no viscosity.

Adhesion promoter, but basically ineffective, then, every car wash, rain or fog weather, moisture will affect the viscosity of the adhesive strip, paste technology is good or good adhesive sealant may be used for a long time, but if cheap or buy poor sealing strip, I am afraid to use a few times after the sealing strip will fall off because of the loss of viscosity.

In fact, I can understand the owners want to reduce noise and sound insulation for the car, want to have a comfortable driving experience idea, but in the face of a variety of sound insulation options, owners should calmly see through the advertising to see the essence, just imagine, if the car's sound insulation problem can be solved by a sealing rubber strip or inhibition.

So why do car companies spend money on door, roof, hood and other parts of the sound insulation? Will money be spent on improved chassis suspension technology, silent tires or advice on oil types? There are many types of automotive sealant on the market, the use of safety, not only to see the performance, but also to see environmental protection.

As long as the glue reaches the environmental protection level, it can be used at ease, and well-known brands are more trustworthy, such as Cosmoor, which focuses on the research of automotive sealant and provides customized automotive sealant application solutions with a wide range of uses and can be applied to new energy.

Military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power, high-speed rail and other industries, users in order to ensure the safety of the glue, in addition to considering well-known brands, but also combined with market reputation and price choice.

Market reputation mainly depends on the user, the brand quality recognized by the majority of users is often not too bad, the quality of the car sealant price is not necessarily particularly high, but also not too low, driving, the car noise by the wind noise, tire noise, engine noise composition, transferred to the car, the design of the vehicle itself determines the wind resistance coefficient and the size of the wind noise.

Not playing sealant can be changed at will, in the process of driving the engine heat will also be emitted through these gaps in the hood, near the windshield side also helps to clear the snow on the windshield during the driving process do not apply sealant without authorization in winter.
