Can the Exhaust Pipe Be Painted If It's Rusty?

[BriellaRose]

Exhaust pipes cannot be painted directly if they are rusty. Rust removal must be performed before painting. Since exhaust pipes operate at high temperatures, it is essential to choose a rust-resistant paint with good flexibility and impact resistance when painting them. Methods to prevent exhaust pipe rusting: 1. Clean debris from the exhaust pipe promptly; 2. After driving in the rain or washing the car, check if there is water in the exhaust pipe; 3. Whenever possible, park the car in a garage to avoid outdoor parking. Parking outdoors can easily lead to corrosion of the exhaust pipe due to moisture in the air, resulting in rust. This can affect the normal use of the exhaust pipe, potentially causing loud exhaust noises or excessive emissions.
