### Understanding the Enemy: What is Rust and Why Does it Form?
Rust, scientifically known as iron oxide, is the result of a chemical reaction called oxidation. This happens when iron or an iron alloy (like steel) is exposed to oxygen and moisture. The oxygen combines with the iron atoms, forming a reddish-brown, flaky substance that weakens the metal. Salt, pollutants, and other environmental factors can accelerate this process.
Think of rust as a slow-burning fire, consuming your car’s metal bit by bit. The longer it’s left untreated, the more extensive the damage becomes. Early detection and prompt action are crucial to preventing costly repairs and maintaining your car’s structural integrity.
