How to Rust Proof Your Car: Everything You Need to Know
Posted on April 15, 2021
Every winter, over 5 million tonnes of road salt is used in Canada to keep roads clear of snow and ice. Unfortunately, these de-icing chemicals can cause rust and damage our cars. Repairing vehicle rust can cost hundreds of dollars, which is why many Canadian drivers choose to get rust protection for their cars.
With a few simple steps, you can protect your car from rust and keep it looking and running great for years to come.
In this guide, we'll break down everything you need to know about rustproofing your car, and how we can make it easy and stress-free.
What is Rustproofing?
Rustproofing of a car entails the use of certain chemicals that are used in an aim of preventing rust and corrosion of the vehicle. This is achieved through the application of a protective layer with respect to your cars’ bodywork.
Some of the rustproofing techniques can extend to the whole car while others only protect the underpart of the car. Basically, when done right, rust protection can sometimes go up to 2 years, giving your car that long-term protection that it deserves.
How Long Does It Last?
Rustproofing can have an 8-year warranty against corrosion perforation as well as annual inspections and reapplications. This means that by getting the right car cover hired, you are confident, and your car will not only be protected and monitored but also free from rust for many years.
Is It Worth Rustproofing My Used Vehicle?
Yes, rustproofing a used car is highly recommended. Applying rust protection can prevent further exposure to the elements and stop rust from spreading. If you plan on keeping your vehicle for a long time, rustproofing is a smart investment. However, if you only plan to keep the car for a short period, rustproofing might not be as necessary.
Is Rustproofing for New Cars Necessary?
Neil Young once said that "rust never sleeps," and he was right. Rust can be a big problem, especially in places with harsh winters like Canada.
Rain, snow, and even humid air can cause rust by creating a chemical reaction called oxidation, which leads to corrosion. This damage can happen quickly and even the sun's UV rays can make it worse.
In colder climates, the combination of moisture and road salt used in winter can accelerate rust formation. This can seriously damage your new car and lead to expensive repairs.
Rustproofing helps protect your car from these elements, keeping it in better condition for longer. If you live in an area with tough weather, rustproofing your new car is worth considering.
Why Rustproof Your Car?
Winter is a major reason to rustproof your car. Modern road salts, including magnesium chloride, stick to your car and can cause rust. It's not just the water and salt, though. Driving on unpaved roads can kick up pebbles and stones that chip your car's surface, making it more vulnerable to corrosion.
At CarHub, we believe in taking good care of your vehicle. If you plan to keep your car for a long time, rustproofing is a smart investment. Even if you don't, rustproofing can save you from costly repairs like fuel line corrosion. Spending a bit on rustproofing now can prevent expensive problems later.
Should I Wash My Car Before Rustproofing?
It’s always advisable to wash your vehicle’s undercarriage before bringing it for rustproofing. It’s best to avoid thick or waxy cleaning products when you do this as well because these can promote air pockets on the surface of the undercarriage, and these are volatile rust zones.
A pressure wash will make sure that you wash away the detritus like dust or mud. Rustproofing on top of either will lead to an ineffective process, and the paint will start to peel in short order, which is a waste of your time, energy, and money.
What Causes Rust in Cars?
Rust, or iron oxide, forms when metals like steel are exposed to moisture and oxygen over time. In Canada, factors like salt, climate, and poor maintenance contribute to car rust.
There are three types of rust:
- Surface Rust: Appears on the paint's surface, near scratches. If caught early, it's easy to treat.
- Scale Rust: Develops if surface rust is ignored, corroding body panels and removing paint.
- Penetrating Rust: If untreated, it can compromise the car's structural integrity.
Regular care and rustproofing can help prevent long-term damage to your vehicle.
How Often Should I Rustproof My Car?
The frequency of rustproofing cars depends on several factors.
First, assess your vehicle's existing protection. Cars with built-in protective plates in key areas like door bottoms and the underside are less likely to rust. Consult a mechanic to gauge your car's rust risk.
Where you live and how you use your car also play a role. Vehicles near saltwater or driven over 50,000 km annually are more susceptible. Look out for areas with chipped paint or bare metal, as these spots are prone to rust.
As a general rule, treat your car at least once a year, especially in Canada. During tire changes, inspect vulnerable parts like exhaust systems, coil springs, and frame areas for signs of rust. Regular checks and timely rustproofing can extend your vehicle's lifespan and save you from costly repairs.
When Is the Best Time to Rustproof Your Car?
Spring is an ideal time to rustproof your vehicle in Canada. With drier conditions and fewer harsh elements on the roads, the rustproofing process is more effective during this season.

Difference Between Rustproofing and Undercoating
While both services aim to combat corrosion and can be performed separately or together, the key distinction lies in their application methods. Rustproofing involves applying wax to specific rust-prone areas like fenders, tailgates, and body panels.
However, undercoating uses a rubber-based sealant or wax to cover the vehicle's underside. Each method offers unique protective benefits for different parts of the car's exterior and undercarriage.
Benefits of Rustproofing Your Car
Rustproofing your car offers more than just cost savings. Consider these additional benefits that enhance the value of your vehicle:
- Extended Lifespan: Preventing rust extends the overall life of your car.
- Reduced Repair Expenses: Rustproofing helps prevent mechanical and electrical issues caused by corrosion, reducing repair costs.
- Higher Resale Value: A rust-free vehicle retains higher trade-in value and sells more quickly.
- Environmental Benefits: Rust-free vehicles and components can be recycled more effectively, reducing environmental impact.
Considering these factors, rustproofing not only protects your investment but also contributes to environmental sustainability.
Tips To Prevent Rust on a Car
While professional rustproofing is the best defense against corrosion, there are proactive steps you can take to maintain your vehicle's longevity.
1. Regular Car Washes
Washing your car removes road grime and salt, which can corrode waterproof barriers. Don't forget to rinse the undercarriage, as it's particularly vulnerable to grime and road salt buildup.
2. Repair Paint Chips
Small paint chips expose metal to moisture and UV rays, accelerating rust formation. Use a touch-up pen from your car's manufacturer to seal chips promptly.
3. Treat Rust Spots Early
If you spot rust, address it promptly to prevent further damage. Surface rust can often be repaired if caught early, preserving your vehicle's integrity.
4. Regular Waxing
Waxing protects your car's paint from UV rays, grime, salt, and acid rain. It also minimizes scratches and makes future cleaning easier by creating a protective barrier.
Rustproofing keeps your car roadworthy long after the warranty expires. While dealerships may offer expensive options at purchase, investing in quality rustproofing treatment and regular maintenance pays off in the long run.
