Is it OK to put sealant on the hood of a car and what are the effects?

It's good, the effect is; 1. Dustproof；If the car is not dense enough, dust will enter the entire car space, making the interior of the car very dirty. The sealant has good compactness and can improve the overall compactness of the car. And the plasticity of the sealant is very good, and the sealant can be applied to glass windows, doors, etc.

2. Moisture-proof；Automotive sealants are not only dust-proof, but also moisture-proof. In summer and autumn, the air humidity is comparatively high. If the density of the car is insufficient, moisture will enter the car along the gap of the car.

The use of sealants on doors, glass windows, etc., can improve the overall sealing performance of the car and prevent moisture from entering. Of course, in order to make the sealant have a good moisture-proof effect, it is necessary to cooperate with a strong supplier. They focus on adhesive research and can provide integrated adhesive application solutions, and can be used in new energy, military, medical, aviation, shipbuilding, electronics, automotive, instrumentation, power supply, high-speed rail and other industries.

3. Sound insulation；Compared with metal materials, automotive sealants have a low density, but the physical molecules after gelling are large and the molecular density is small. Based on this characteristic, the sealant has a good sound insulation effect. If the car is not soundproofed well, the sound of the engine and the noise from the outside world can spread to the car, which can affect the mood of the car user.

The use of sealants in automobiles can effectively isolate the engine and various external noises, thereby improving the comfort of car users.

4.Shock absorption；The physical properties of the sealant determine that it is more elastic. If the elasticity of the car is not good, then during use, due to the lack of elasticity of the car, it will not only affect the comfort of the car user, but also accelerate the aging of the car and affect the service life of the car.

The sealant is applied to automobiles, which can effectively improve the elasticity of automobiles and prolong the service life of automobiles. In addition, sealants have functions such as thermal insulation and insulation.

Summary; The advantages of automotive sealants are very important, which can improve the overall performance of the car, extend the service life of the car, and reduce the cost of the car.

This should have an impact on the operation of the engine, so it will affect the operation of the engine.

Of course, it is not good, this will affect the heat dissipation of the car, and the life of the car will be affected.

It's better not to seal it, sometimes it's hard to open it if something goes wrong, and it also needs to dissipate heat.

You can't ask for this, otherwise your car won't be able to dissipate heat.

Not very good, because this will cause the engine to dissipate heat more slowly, which is harmful to the car.

Actually, it's also good. It can have a dust-proof effect, and it also has a certain anti-noise effect.

Sticking sealant on the hood of the car is good for the car, effectively preventing external debris from falling into the engine compartment, and indirectly prolonging the life of the car, and there are many people who paste it.

Pros: Isolate part of the wind noise and block engine dust to improve comfort.

Disadvantages: It affects the heat dissipation of the engine, when the engine water temperature gauge is too high, the working time of the high-speed gear of the electronic fan is too long, the engine noise increases, and the fault is most obvious when the air conditioner is turned on when the temperature is too high.

Adding heat insulation cotton on the induction cover, from a thermal point of view, is nothing more than to prevent the heat of the engine or cabin from being transferred to the cover, so as to achieve the paint that protects the surface of the cover, but from the perspective of heat dissipation, it is necessary to transfer the heat of the engine to the outside world as much as possible to achieve temperature balance. The temperature inside the engine and nacelle will then rise to achieve a new temperature equilibrium.

The heat dissipation is not good, and the closure is not tight. The benefits are sound insulation, preventing foreign objects from entering, and closing the lid quietly. Personally, I don't think it's necessary to install a seal.

Hello, generally speaking, it is not recommended to add a seal on the hood, if the original car has a seal, it is not recommended to add it, if not, you can consider adding, too many seals may cause the closure to be not tight and there is an abnormal sound, I hope my answer makes you satisfied, I wish you a happy car.
