Rust can be a major issue for anyone who owns or restores classic and vintage cars. The gleaming chrome and flawless paint you once admired can quickly become marred by rust, potentially leading to costly repairs. Unfortunately, many of these older vehicles were built with materials that made them highly susceptible to corrosion from the start.
Classic cars from the 1950s through the 1970s often used 22-gauge steel without the protective zinc coating that modern cars have. This made them more prone to rust, especially in areas exposed to moisture and road salt. As a result, many of these vehicles require extensive restoration to bring them back to their original condition.
There are several types of rust you may encounter when restoring an old car:
- **Surface Rust**: This is the most common type and appears as a thin layer of oxidation on the surface. It usually occurs due to moisture exposure.
- **Pitting or Scale Rust**: This happens when rust penetrates below the surface, causing the metal to look pitted. While it can often be fixed with sanding and repainting, it's important to address it early.
- **Rusted Body Panels**: In severe cases, entire panels may be completely corroded and need replacement. If there’s a hole, the panel must be replaced to maintain structural integrity.
When buying a classic car, always inspect it thoroughly for signs of rust and structural damage. Some areas, like under the doors or around the wheel wells, are particularly vulnerable.
To keep your classic car in top shape and prevent rust, regular maintenance is essential. Fix any dents or scratches immediately, as even small damages can lead to rust. Store your car in a dry, enclosed space, and avoid using plastic covers, which trap moisture. Clean and wax your car regularly, and make sure it’s fully dry before storing.
If you find rust, don’t just paint over it—properly remove the rust first. If you're doing the work yourself, get the paint color ready in advance to avoid leaving bare metal exposed for too long.
