Surprising Things About Rust on a Vehicle

Many drivers, especially those who own older cars, despise rust spots. It’s as if your automobile had a huge sign on it that said “old.” Rust is a common sign that your car needs some tender loving care, but do you know what to do if you notice it on your vehicle? In this article, we discuss a few surprising things about rust that you may not know.


What causes rust on cars?

When iron-based metals undergo electrochemical breakdown, they begin to corrode. This breakdown causes rust on cars, and it is due to the oxidation process of the parts. Iron surface molecules react with oxygen in the environment to form Fe2O3, also known as iron oxide. Rust is essentially iron oxide.

Exposed steel rusts at different rates based on the alloy components, thickness, climate, and type of heat treatment it receives. Surface rust appeared on badly constructed cars as soon as they arrived at the docks back in the 1970s. In as little as a few years, untreated raw sheet steel can rust.

Then there’s salt! Electrolytes impurities such as road salts and other toxins are found on roads. The exchange of molecular components is increased when electrolytes are introduced to a chemical process. It explains why automobiles in northern regions, where salt is used in the winter, and cars that spend a lot of time near the coast decay at a faster rate.

4 Surprising things you might not have known about rust on a vehicle

There are a few urban legends about rust that you should be aware of, as well as certain variables to consider while dealing with this problem. As a result, you will be able to avoid it in the future and provide better care for your automobile.

Wintering in Garages

Does parking your car in a parking lot or garage save it from rust? The garage protects your car’s paint and finish from the sun’s harmful rays and rust-inducing rain in the summer. During winter storms your automobile is safe and warm inside the garage, away from the snow and ice.

However, this isn’t the whole tale. It’s common knowledge that the salt we use to treat our roads throughout the winter is bad for your car’s body panels and undercarriage. Salt causes metal to rust. Pretty much any winter driving is hazardous for your car’s metal parts.

Most people are unaware that storing their car in the garage during the winter can exacerbate the rusting effects of road salt. Although the salt-filled snow and slush that clings to your automobile is unpleasant, it is not as bad if it remains frozen.

The slush might melt from the heat of the engine when you park your car in the garage, even if it isn’t heated. The rust-causing qualities of the salt are exacerbated by the water that comes from the melted slush. This can result in more rust damage than if the vehicle was left outside.

Because of the cooler temperatures and lack of air in the winter, the dampness in your garage does not dissipate rapidly. As a result, your car might be wet for longer periods of time than it can be dry. Salt has extra time to conduct its dirty work because of the extended moisture. The entire corrosion-causing process repeats itself every time you take your automobile out and back in.

Rust Proofing 

Even if the car shows signs of oxidation, there is still hope if you act rapidly. Keep in mind that there are different rust proofing solutions. You should contact a rust specialist who can advise you on the best approach based on your car’s situation.

What is a rustproofing treatment? 

 Are New Cars Rust Proof?

In order to reduce wind resistance and enhance fuel economy, most cars on the market today have plastic covers around the body of the chassis. This does not, however, prevent huge amounts of moist dirt from gathering between the vehicle’s undercarriage and the plastic covers, which aids in the development of corrosion over time.

When compared to vehicles from prior decades, dealerships may claim that modern cars have a corrosion advantage, but this does not mean that they are immune. It simply means that corrosion takes longer to form.

Most Cars are Galvanized

Galvanization is a term that has recently gained popularity among manufacturers as a result of its benefits. To put things in perspective, when iron in a vehicle mixes with oxygen, rust (iron oxide) forms. By covering the iron with an appropriate non-reactive element, this oxidation process can be avoided. The process is known as galvanization when this element is zinc.

Because the procedure is relatively inexpensive, numerous automakers are using it. Furthermore, because oxygen and zinc do not react like iron and oxygen, galvanized steel does not rust until it is scratched, the zinc coating completely prevents rusting.


How do you rustproof a car?

So you have spotted signs of rust, but with so many rustproofing alternatives on the market, deciding which one is best for you, if any, can be difficult. To make that selection a little easier, here are four of the most frequent rust proofing methods.

Electronic Module

An electronic rust inhibitor system is one of the newest and most contentious systems of rust proofing. These systems send a mild current through a vehicle’s metal body, protecting it from corroding by reacting with oxygen. Experts and consumers alike have conflicting opinions on the effectiveness of these gadgets in practice. An electrical module is a significantly less invasive alternative for your vehicle when compared to some of the other ways.

Tar-Based Spray

Tar-based sprays, sometimes known as undercoatings, were first introduced in the 1950s to make car trips calmer. Spraying a black, tar-like substance over the floor pans, wheel wells, and other exposed sections of your car’s underbody, which then hardens and functions as a permanent shield against moisture, salt, and other elements, is the technique. Unfortunately, moisture can seep through the thick exterior barrier and corrode the metal beneath it over time.

Dripless Oil Spray

In the same way that tar-based spray hardens after being sprayed, dripless oil hardens after being sprayed, producing a moisture seal for your vehicle. It has a solid waxy feel and adheres to the frame of your vehicle without run-off. A dripless oil spray covers more surface area than its tar-based cousin since it is applied to more interior sections of the car, but this increased protection comes at a cost.

To maximize the area covered, the application technique frequently entails drilling holes into the vehicle’s structure. These holes are discretely drilled and should not be apparent if done by a competent professional.

Drip Oil Spray

A drip oil spray, as the name implies, is a thicker variation of the dripless oil spray. It’s done in a similar way, with holes bored into the body of your car. This form of rust proofing is the most frequent and recommended since it can completely rust protect your vehicle by penetrating all of the microscopic nooks and crevices.
