Does chassis armor need to be sprayed? Master of Auto Repair Factory: The effect is not so magical, but it really works.

Chassis armor is a part that car owners tend to overlook when buying new cars. Car owners tend to pay more attention to things like car membranes and interior mats. Sales consultants also grasp people's psychology. Anyway, the cost is not high, try to deliver it in place. As for chassis armor, there are not many 4S shops in this line now, and there are naturally few opportunities to talk about it. So is chassis armor necessary for new cars? Many car owners have had such questions, so let's talk about it today.

What is chassis armor?

Chassis armor is not a set of "armor" directly installed on the chassis, but an antirust glue containing asphalt, oil or water-soluble materials is sprayed on the chassis. It covers the exposed part of the chassis, and after cooling and solidification, it will form a dense protective film to protect the automobile chassis.

Then, someone stood up and opposed it. They said that the manufacturer had taken precautions before leaving the factory. To put it simply, they have done anti-rust and anti-corrosion treatment. It's wasteful, unnecessary and disdainful to buy and spray chassis armor later.

This statement is not unreasonable, but in fact, quite a few cars still appear messy after driving for a period of time, and the corroded place is still corroded, especially in the humid and acid rain coastal areas. The protection made by the manufacturer before leaving the factory is very simple, and it also costs a lot to electrophoresis in white body and anti-rust spraying all over the body. Layers of fluffy chewing gum can be seen under the chassis of the higher-priced car, which shows that this car is doing better in this respect. But for cars under 200 thousand, this preventive measure is not satisfactory on the chassis.

Chassis armor is not only rust-proof, but also has other uses.

First of all, the thick chassis armor can isolate the damage caused by the stones raised during driving, and good thermal insulation can weaken the baking of the chassis in summer. In addition, it can also isolate the rain of acidic substances, or prevent the gravel splashed during driving from damaging the chassis. These are the original intention of chassis armor and the main reason why people choose to make chassis armor.

As for some people who say that spraying chassis armor can isolate noise, the improvement is very small. The main noise when a car is driving comes not only from the chassis, but also from wind noise and tire noise. Spraying a little rubber material can silence the sound, which is a bit of false propaganda.

Spraying chassis armor also has a lot to pay attention to.

Oil pan and gearbox oil pan need heat dissipation and are not suitable for spraying. Because the car body support needs activities and is not suitable for spraying, the places that need spraying are mainly concentrated in the fuel tank and the car body floor. In addition, the bottom of the car must be cleaned before spraying, otherwise its adsorption capacity will be affected.

Having said that, I believe everyone has a clear answer about whether to spray chassis armor. Chassis armor has low cost and simple operation. Suitable for DIY. You can consider giving it a try when you buy a new car.
