How Does Rust Occur On Classic Cars?
In scientific terms, rusting is the chemical process of surface molecules reacting with oxygen in the air and producing new molecules, called Fe2O3, which are known as iron oxides. Rusting is a natural process for cars if you leave the cars iron cover to the elements, it will eventually reduce to iron oxide.
Classic cars that were produced during the 50s, 60s, and 70s were more poorly made and many of them began to show rusting signs as soon as they came off the assembly line. If left untreated, the main sheet panel can completely rust in a matter of years. Its easier to repair rust when you notice the first few signs appear, rather than having to re-do the entire car.

Rust Repair Or Is It Too Late
Rust is a recurring issue for car owners, but how much rust is too much rust? How do you know if its too late for car rust repair? And if youre shopping for a used car, should rust be considered a deal-breaker?
Rust generally falls under one of two categories: surface rust or scale rust .
- Surface rust is superficial but repairable! It affects the metal surface on a microscopic scale, going only a few microns deep. Typically, surface rust can form after a paint chip or scratch has left the metal exposed to the elements for an extended period of time. How fast surface rust progresses to scale rust depends on temperature, humidity, and precipitation.
- Scale rust is a natural progression of surface rust. As oxidation works its way deeper, it accelerates, flaking off bits of the converted metal. At first, this will cause pitting, and then paint will eventually start to bubble and flake off. Over time, scale rust eats holes through body panels, frame rails, and chassis components, affecting your vehicles structural integrity.
