Voiture endommagée par la rouille

How can rust damage your car?

Rust is a silent killer of automobiles. It has the ability to turn a high-end vehicle into a clunker. It diminishes a vehicle’s market value and, if left untreated, renders it unsafe to drive. Ignoring it could lead to your car’s demise. Thankfully, understanding what causes rust and knowing how to check a car for rust can help you avoid costly problems in the future. In this car rust guide, we tell you all you need to know about rust damage, surface rust repair, and protective coatings to protect your vehicle!

What is rust?

Rust’s chemical name is iron oxide and it is made of two iron atoms and three oxygen atoms. It occurs as a result of an electrochemical reaction known as corrosion. Corrosion occurs when an iron-containing metal, such as the body of your car, is exposed to oxygen and moisture for an extended period of time.

To appear, rust merely requires two electrodes (anode and cathode) and an electrolyte. The electrodes are already present in the metal surface of your car. After that, all you have to do is add water (electrolytes) to create the ideal rust environment.

Additional oxygen is provided when electrolytes are given to these specific electrodes. This creates a chemical reaction, which causes the anode to release electrons. Electrons flow between the two electrodes via the water, which functions as a carrier. The anode develops an oxidized ceramic layer as a result of this, which leaves a rusty mark on your car’s body.

What are signs of rust on a car?

One thing to keep in mind when it comes to rust is that it usually starts near the bottom of an automobile. Unfortunately, because the underside of a car contains so many vital components, this can be a major safety concern. How old the car is is another indicator that rust may be chewing through your vehicle’s metal.

As a result, we recommend inspecting the bottom of your car first. Take the automobile to a mechanic who can put it up on a lift if you are concerned about corrosion. The frame rails, which run below a car’s doors on both sides, the wheel wells, the exhaust, the suspension, and almost any other steel or metal underbelly component are common rust spots that can be better inspected with a garage lift.

Pull up the trunk carpeting and check for any signs of corrosion once the car is back on the ground. Check the inside and outside doors, as well as the regions surrounding the windshield and back glass. Also, any external paint that is bubbling is most likely an early sign of rust.

What problems can rust cause?

Here are common problems that rust can cause:

  1. Reduced product lifespan
  2. Sudden breakage
  3. Safety concerns
  4. Rust holes

Rust can harm an automobile by eating away at the body and chassis, resulting in structural failure. When this happens, a vehicle is deemed too dangerous to drive. The paintwork on your car prevents water from being in contact with bare metal. The exposed metal will eventually rust if your paintwork is scratched, chipped, or damaged by acidic bird droppings.

Another important cause for concern is rust inside the engine. Low-quality gasoline or, more typically, humidity might allow water to enter. This can cause scoring if it occurs inside the engine cylinder and comes into touch with the pistons. Modern lubricating systems prevent this, although caution should be exercised when using low-quality fuel.

Electronics and electrical systems in modern automobiles are growing increasingly complicated, yet rust can still wreak havoc on them. They’re usually well protected, but if water gets inside your car on a frequent basis, the electronics can short out and stop working completely.

1. Reduced Product Lifespan

Rust weakens metal by reducing its mass, therefore after a significant amount of rusting occurs, the piece of iron may be unable to support the weight it formerly did. Raw materials must be utilized to replace and repair any broken structures. This explains why preventing rust in the first place is the economical choice.

2. Sudden Breakage

Rust on the frame is a major worry since it compromises the car’s structural integrity. Frame rust that is severe enough might cause parts to snap off or crack, endangering you, your passengers, and other motorists. It may also reduce the car’s ability to protect you in the event of a collision. Other rusty components may necessitate expensive repairs. Rusty brake and gas lines, which can be costly to fix, are another source of concern. 

3. Safety concerns

The normal automobile’s metal chassis provides a safe foundation for drivers to drive in. Rust jeopardizes this structure by attacking the metal’s integrity. Rust, for example, can eat away at the metal surrounding a vehicle’s gas tank, puncturing the fuel line and causing gas to spill out when the vehicle is refueled. Even worse, damage to a vehicle’s structure impairs its capacity to adequately absorb impact damage.

4. Rust Holes

Corrosion on the car’s thinner sections often results in rust holes. This can cause serious safety issues and decrease the aerodynamics of the car. You certainly don’t want to be breathing fumes from your exhaust or endangering other drivers with body panels flapping or flaking around.

What should I do to stop rust on a car?

Here is what you should do to prevent and stop rust on a car from spreading:

  • Clean your car
  • Inspect exposed areas
  • React quickly 
  • Anti-rust coating

Clean Your Car

Although it may seem counterintuitive, the greatest approach to prevent rust is to use more water. Don’t wait until your car’s paintwork is clearly dirty to wash your vehicle because road filth will coat the metal of your undercarriage.

Cleaning your automobile with any method is preferable to not washing it at all, but it’s best to clean it with a high-pressure cleaner. This makes hard-to-reach areas such as the inside of wheel arches and tough corners in the undercarriage easy to clean. It is recommended that you wash your car once a week and have it professionally cleaned every two months.

Inspect Exposed Areas

Keep an eye out for any rust or damage to the paint that has exposed the vehicle’s metal body while you’re washing it. Check the condition of any seals, water channels, or drain holes in particular. When things fail to function as they should, rust can rapidly develop.

React Quickly 

Once you’ve spotted a possible rust spot, addressing the issue before it’s too late can save you hundreds, if not thousands, of dollars in the long run. The more rust on a vehicle, the longer it takes to repair it and the costlier it is.

Anti-Rust Coating

Several layers of rust protection are used by car manufacturers, and you can even buy some off the market. An anti-rust treatment eliminates potential corrosion concerns if you live in an area like Quebec where climatic conditions make the development of rust more probable. Antirouille Champlain offers a paraffin-based anti-rust treatment that will safeguard your car’s components.

Anti-Rust Treatment Services

The majority of rust issues can be avoided by regularly inspecting your vehicle’s paint job and following a washing and waxing schedule. A yearly anti-rust treatment application can save you thousands of dollars and extend the life of your car.
