Do classic cars rust more often?

Rusting is often dependent upon the material rather than the age of the vehicle. Modern or vintage vehicles, all cars have to deal with the corrosion issue at some and time. Some people think that classic cars rust more often as compared to contemporary cars.

In this article, we will critically analyze this statement and check whether there is any truth to it or not. In addition to that, we will also point out the parts that are more prone to catch rust.

What is Rust And Why It Occurs?

The eating away of the metal due to long exposure to moisture is called rusting. The oxidation reaction takes place on the surface of the metal in presence of water and air and as a result oxides of metal are formed. This chemical reaction is called corrosion. The terms rusting and corrosion are usually synonymous. The only difference is that corrosion is the chemical reaction and the action of that reaction is rusting.

Corrosion makes metal porous and compromises its strength and integrity. Rusting is a reality which we all must accept. Engines and other systems of the cars break down and demand repair. Similarly, rusting of the exterior panels occur and car owners have to deal with it. But you should not take it lightly because it progresses very fast. And by the time you take notice, it is already too late. You have to change the whole body panel which is a costly affair.

Do Classic Cars Rust More Often?

Yes, it is true to some extent that classic cars rust more often. There are multiple reasons for this. These include the age of metal, more exposure to extreme weather conditions, and the absence of protective coatings. All these reasons come about to make classic cars more prone to corrosion.

Why Do Classic Cars Rust More Often?

Classic cars rust more often due to the following reasons:

  1. Age of Metal
  2. More Exposure to Extreme Conditions
  3. No Protective Coating

Age of Metal: In corrosion, the age of the metal plays a very critical role. As the metal ages, it becomes weaker and weaker due to the continuous operation. The strength of the metal is nothing but the strength of its bonds. When the body of the car made out of metal is continuously subjected to a fatigue cycle in form of air drag, the bonds weaken, and the strength of the metal is compromised. This weak metal is less capable of fighting corrosion than a newer and sturdier material.

More Exposure to Extreme Conditions: The older the car the more time it has spent fighting the extreme weather conditions and it is more likely that it has met a high number of accidents. The longer exposure to extreme weather conditions highly undermines the capacity of metal to fight corrosion. Similarly, older car has higher chances of being involved in accidents. Dents and scratches on the surface of the car are an open invitation for rusting.

No Protective Coating:

Classic cars are usually built on primitive knowledge and technology. This promotes the rusting of vintage cars in two ways. One is the obvious reason that classic cars often lack extra protection. The other is the utilization of older metal joining techniques that leaves more room for rusting.

Classic cars didn’t have the best tool against rusting, galvanization. In modern cars, all most all car parts are hot-dip galvanized. This gives them longer life and resistance against rusting. In addition to that, in older cars metal sheet joining methods were not as effective as they are today. They left pores and other welding deficiencies more often. That left the scope for moisture to be trapped and attack the metal. Due to these reasons, classic cars are more prone to fall prey to rust.

Which Parts of Classic Cars Rust More Often?

Frame rails, wheel wells, and lower chassis are the parts of classic cars and all cars in general that rust more often. Well, it should be abundantly clear by now that parts that are longer exposed to moisture or parts that are less likely to get noticed will rust more often.

Frame rails are the thin metallic sheets that run around the car under doors. This is the best contender to catch rust as it has extended exposure to dirt and moisture. Similarly, wheel wells are curved domes above wheels. These areas are the safe house of dirt and debris. All these parts are located at the bottom of the chassis, hence we don’t observe them every day. We only notice rust on the bottom of the car after it has progressed beyond control.
