Addressing Rust with Classic & Vintage Cars

What once looked like a pristine chrome finish or flawless paint job can quickly become a source of frustration when rust begins to take over. In some cases, the damage is so severe that major repairs or even complete restoration are necessary.

Back in the day, many classic and vintage cars were built with materials that weren’t as resistant to corrosion as today’s models. For example, cars from the 1950s through the 1970s often used 22-gauge steel without galvanization, making them highly susceptible to rust. This means that even if a car was well-maintained, it could still develop rust issues over time, especially in areas where moisture tends to collect.

Today, most cars come with galvanized steel and protective coatings to resist rust, but older models don’t have this advantage. As a result, many classic cars need extensive work to bring them back to their original condition. If you're thinking about buying a vintage car, it's important to understand the different types of rust you might encounter and how they affect the vehicle's value and safety.

Common Types of Rust Found on Classic Cars

When inspecting a classic or vintage car, you may come across several forms of rust:

  • Surface Rust: This is the mildest form and usually appears as a thin layer of oxidation on the surface. It can occur even in well-maintained cars due to exposure to humidity or rain.
  • Pitting or Scale Rust: This type of rust occurs beneath the surface, causing small pits or flaking on the metal. While not always serious, it can weaken the structure over time if left untreated.
  • Structural Rust: This is the most dangerous form, where the metal has been completely eaten away, creating holes or weak spots. In such cases, parts may need to be replaced entirely, which can be costly and time-consuming.

It's crucial to thoroughly inspect any vintage car before purchasing, especially around the undercarriage, wheel wells, and door frames—common areas where rust tends to start.

How to Prevent Rust on Your Classic Car

Keeping your classic car in top condition requires more than just regular washing and waxing. Here are some tips to help prevent rust:

  • Fix any dents or scratches immediately. Even small damages can allow moisture to seep into the metal and cause rust.
  • Store your car in a dry, enclosed space. Avoid using plastic covers, as they trap moisture and speed up the rusting process.
  • Keep your car clean and dry, especially after driving in wet or salty conditions. Always dry underneath the car and in crevices where water can accumulate.
  • Regularly check for signs of rust, especially around the wheels, frame, and body seams. Early detection is key to preventing major damage.
  • If you find rust, don’t just paint over it. Proper rust removal and treatment are essential before applying primer and paint.
