How to paint a car muffler so that it does not rust - paint selection and processing technology
Content
Painting a car muffler with refractory powder paints, as a rule, takes place in industrial conditions. The composition, in comparison with silicone heat-resistant counterparts, makes it possible to withstand higher temperatures. The main disadvantage is the complexity of application.
The exhaust system of a car that removes exhaust gases can heat up to a temperature of several hundred degrees. Therefore, the paint on the pipe burns over time, which reduces protection. Because of this, the part suffers from corrosion. Therefore, motorists often decide to paint the car muffler so that it does not rust.
How to paint a car muffler so that it does not rust
It is impossible to paint the muffler with the same composition that was used for the car body. A heat resistant coating is required. For example, you can paint a car muffler so that it does not rust with a silicone-based heat-resistant compound.
Protect car muffler from corrosion
To increase the life of the exhaust pipe, motorists use two main methods:
- Drilling a hole in the pipe to drain the condensate.
- Application of heat-resistant paint.
The first method allows the condensate to escape, thereby preventing the accumulation of liquid and the formation of rust. Despite the effectiveness, not all motorists are ready for such radical interventions.
So, painting a car muffler to prevent rusting with special paint is often the only way to combat corrosion. This protects against rust and prevents accelerated aging of the metal from high temperatures. The best option is to paint the calipers with silver enamel: this is a reliable method, moreover, it is pleasant and at a price.
Is it legal to paint a muffler on a car?
Whether to paint the exhaust pipe is up to you. Factory painting, which is mainly responsible for a presentable appearance, soon after the purchase of the car begins to lose integrity. In addition, scratches are possible already during installation, and welding work reduces the protective characteristics of the top layer.

Although it is not coated on the inside, properly applied to protect the car muffler from corrosion on the outside, the paint still protects for some time, significantly extending the life of the part.
Paint selection for a car muffler
Make the choice of paint for the muffler according to the main parameters:
- Heat resistance (the higher the better: the exhaust pipe can be heated up to 600 degrees, so its temperature range should be -35 to 600 degrees Celsius).
- Anti-corrosion.
- Water resistant.
- Painting characteristics: structural uniformity, color saturation, drying speed.
It is best to buy silicone enamel or heat-resistant varnish.
Heat resistant
Silicone heat-resistant paints are popular among car enthusiasts, as they are easy to use (applied in several layers and do not require a primer).
Painting a car muffler with a heat-resistant composition not only protects against rust, mechanical damage and chemicals, but also extends the life of the exhaust pipe, making it resistant to high temperatures.
Heat resistant muffler paint
There is an important point that highlights the heat-resistant paint for the muffler: for its hardening, the composition must be heated to 160-200 degrees. This can be done with a hair dryer or a high temperature oven. The drying period of each layer is 15-20 minutes.
Refractory
Painting a car muffler with refractory powder paints, as a rule, takes place in industrial conditions. The composition, in comparison with silicone heat-resistant counterparts, makes it possible to withstand higher temperatures. The main disadvantage is the complexity of application.
Serebryanka
The best paint for a car muffler is silver. At the service station, it is most often made silver or black: these shades are able to withstand temperatures up to 600 for a short time, and up to 400 degrees for a long time. Other colors are less heat resistant.

Painting this part is an important process that is best left to experts who use the right equipment and quality materials. The procedure will take a minimum of time and will be carried out qualitatively.
However, if you decide to do it yourself, remember that it is better to update the color on a new part: painting a used car exhaust pipe, especially without prior preparation, will not provide a long-term result.
You will need the following equipment:
- paint;
- a hairdryer;
- gloves, protective suit and mask;
- brush with metal bristles;
- degreaser.
Clean with a metal bristle brush or a drill with an abrasive wheel. Then treat the pipe with a degreaser.
Heat-resistant paint must be of high quality. In order not to redo everything over again, follow the instructions.
