Is Rustproofing Worth It?

For both car enthusiasts and the average driver, the question often arises: Is rustproofing worth it for your car? Think of rustproofing as a form of protection, similar to car insurance. While there’s an initial cost, it can lead to long-term savings. In this article, we’ll explore various rustproofing methods, address common misconceptions, and delve into the core of the topic.

What is Rustproofing and Why Should You Care?

Rust is the result of an interaction between iron, water, and oxygen. It’s that reddish-brown flaky stuff that you might have seen on old bikes, gates, or, unfortunately, cars. For those residing in areas where road salts are generously used during winter, like Ontario, rust can be a real menace. Rustproofing your car is a preventative measure you can take to ensure that your beloved vehicle is protected.

Fun Fact: Did you know that rust is actually iron oxide? It forms when metal is exposed to moisture and oxygen for extended periods. And if you add salt to the equation, the rusting process accelerates, emphasizing the need for rustproofing car techniques.

Should You Rustproof Your Car?

Rust isn’t just an aesthetic issue. It can compromise the structural integrity of your vehicle. Think of rust as the silent car killer. Over time, it can eat away at the car’s body, leading to potential safety hazards and a decrease in your vehicle’s value. This brings us to the question, “How does this relate to my pocket?” Well, rust can lead to:

  • Increased repair costs.
  • Decreased resale value due to lack of car rust protection.
  • Shortened vehicle lifespan.

Rustproofing is one way to maintain a car’s value, especially if you’re considering selling it in the future. Whether you’re thinking of buying a new or used car, understanding the benefits of rustproofing can be crucial. If you’re on the fence about which type of car to buy, check out our guide on whether you should buy a new or used car.

How to Rustproof Your Car

There are several methods to rustproof your car, but the most common ones include:

  • Grease-based treatment: Lasts for the car’s lifetime with occasional touch-ups.
  • Oil treatment: Needs to be done annually.
  • Electronic rust protection: Uses an electrical current to prevent rust.

Is Rustproofing Your Car Worth the Cost?

The short answer? It depends.

If you’re planning to keep your car for just a few years, you might skip it. But if you’re looking at long-term ownership, especially in rust-prone areas, it’s a resounding YES. Considering the rustproofing cost, it’s an investment that can save you in the long run.

Salt & Rust: A Corrosive Relationship

Road salts, commonly used in regions like Canada during winter months, play a significant role in accelerating the rusting process.

According to Environment and Climate Change Canada, while road salts are crucial for safety, their environmental impact cannot be ignored. It’s a delicate balance between ensuring road safety and protecting our vehicles from premature rusting. When salt comes into contact with the metal parts of a vehicle, especially in the presence of moisture, it speeds up the oxidation process, leading to faster rust formation.

For those residing in areas where road salts are generously used during winter, rust can be a real menace. Rustproofing is just one aspect of winter car care. To ensure your vehicle is fully prepared for the colder months, read our comprehensive guide on preparing your car for winter.

The Financial Implication of Rustproofing Your Car

Considering the cost of rustproofing, it’s seen as an investment.

Rustproofing a car typically costs between $130 to $150, and for an SUV or truck, it’s around $150 to $170 in Canada. These costs can vary based on the service provider and the method of rustproofing chosen. For instance, drip oil sprays like Rust Check and Krown range from $130 to $160 and are recommended annually.

On the other hand, dripless oil sprays like Corrosion Free can cost between $130 to $170 every 18 months. While there’s an upfront cost, the long-term savings from reduced repair costs and maintaining the vehicle’s resale value can make it a worthwhile investment.

Car Components Commonly Affected by Rust

It’s essential to understand that rust doesn’t discriminate. While some parts might be more exposed and vulnerable, various components can be affected. Some of the commonly impacted parts include the muffler and exhaust system, door and rocker panels, coil springs, floor panels, frame, sub-frame, and even the hood. Ignoring these can lead to functional issues, compromised safety, and a decrease in the vehicle’s overall value.

The Bottom Line

Rustproofing is not just about maintaining the aesthetic appeal of your car. It’s about ensuring safety longevity, and getting the best value for your vehicle in the long run. With the added challenges posed by environmental factors like road salts, rustproofing becomes even more crucial in regions like Canada. So, while there’s a cost associated with rustproofing, the benefits, in the long run, make it a decision worth considering.
