Can the car exhaust pipe be sprayed with anti-rust paint? How to prevent rust on the exhaust pipe

The exhaust pipe is a component that discharges waste generated by fuel during driving. It is part of the engine exhaust system and also has a muffler function. The exhaust pipe is made of metal. Sometimes you may find it rusty. Some new cars may rust after just half a year of driving. So can the car exhaust pipe be sprayed with anti-rust paint?

Can the car exhaust pipe be sprayed with anti-rust paint?

You can spray, but it's not necessary.

Painting the rusted exhaust pipe will not solve the problem. There are two main reasons: the exhaust pipe temperature is high, and most exhaust pipes rust from the inside. When the engine is running at high speed, the exhaust temperature can reach 800 to 900 degrees, and it only takes a few seconds to burn the paint. So even if you spray paint, it will be burned soon. Another problem is that the rust on the outside of the exhaust pipe is not fatal, because the surface of ordinary steel exhaust pipes will rust during normal use. This is the result of natural oxidation and is not too serious. Generally, there is no need to worry.

The most feared thing about the exhaust pipe is internal rust. Because there is water vapor in the exhaust gas, part of the water vapor will turn into liquid water and exist in the exhaust pipe when the car is running, causing the exhaust pipe to rust from the inside. We cannot find this kind of rust at the first time, and by the time we find it, it is basically damaged.

How to prevent rust on exhaust pipe

Under normal circumstances, automobile exhaust pipes need to be processed and manufactured with stainless steel or stainless iron, so that the exhaust pipes will not rust. However, in order to reduce costs, many automobile manufacturers use ordinary steel plates or inferior stainless steel to manufacture exhaust pipes, which makes the exhaust pipes prone to rust. Punching holes at the low end and draining water in time. Stainless steel material, electroplating, and high temperature resistant paint are also good ways.

It is difficult to completely solve this problem, unless you replace all the exhaust pipes, you will have to make do with it.

What to do if the exhaust pipe of a new car is rusted

First of all, this is a new car and it is covered by the warranty. If you are worried, you can go to the 4S shop for inspection. If there is a problem due to rust, the 4S shop needs to be responsible.

Normal cars need to apply a kind of glue to the rust-prone areas before leaving the factory to prevent rust. In your case, it is best to go to a 4S shop for a check-up.
