Why do cars rust?

Rust is a reddish or yellow-brown, flaky coating that is formed by the electrochemical breakdown of iron-based metals. When metal is exposed to moisture for a long time, it begins to oxidize and thus, rust (iron oxide) accumulates on the surface.

  • Scratched or chipped areas of a car are prone to rusting.
  • Extreme weather conditions play a prominent factor in rust formation as heavy rains make cars more vulnerable to rust.

If you have a car with rusted parts that does not mean that your vehicle is doomed. Once you know about the main rust locations and how to fix it with major rust repair, then you can easily bid adieu to these ominous brown stains.
