Rustproofing vs. Undercoating – What’s The Difference?


You’re a car owner in the Greater Toronto Area, you know that winter driving can do a number on your vehicle.

The region is known for its snow, ice, and slush during the cold weather season. That’s why regions throughout Ontario use salt, sand, and other treatments to make the roadways more manageable.

These roadway treatment products help to keep the roadways and highways more drive-able for motorists, but they also create rust issues. That’s where undercoating and rustproofing treatments come into the picture.

But what are the differences between undercoating and rustproofing? They’re similar — but not synonymous — terms. Read on to find out what these terms mean, and what they mean to you as a vehicle owner.

Consider the Vehicle Focus Area of Undercoating and Rustproofing

One way you can differentiate undercoating from rustproofing is by looking at the focus of these treatments.

On the one hand, undercoating uses a tar based substance to focus on the chassis and underside of your car, truck, van, or sports utility vehicle. So the focus area in your vehicle is larger than is the case for auto rustproofing.

On the other hand, automobile rustproofing uses a dripless wax-like oil that focuses on specific sections of your vehicle where rust can take root, grow, and ultimately create damage.

Specially trained staff will use a protective wax to prevent rust from forming or to inhibit existing rust from spreading. They will focus on the rocker panels, the tailgates, the fenders, the body panels, the doors, and the hood.

Consider the Order of the Treatments

Another way to look at undercoating and rustproofing is to see how each fits into the overall process of protecting your vehicle.

For instance, it’s common to get undercoating ahead of getting corrosion free rustproofing. You can go to an automotive centre – or come by our shop if you’re near Pickering – have them apply the undercoating, and then enjoy the protection from stones and moisture.

After getting the undercoating, you can up the ante by getting rustproofing. This will involve applying the product inside the doors, inside the frame, inside the hinges and door jams, and more.

Consider Your Goals as a Vehicle Owner

Yet another way to differentiate undercoating from rustproofing is by considering your goals.

If you’re more focused on ensuring the exterior of your vehicle looks like it just rolled off the assembly line, then you’ll want to get it rustproofed rather than undercoated.

But if you’re focused on ensuring top functionality over the long-term period, you’ll likely favour getting your car undercoated rather than rustproofed. This is especially the case if you travel roadways treated with salt in the winter.

Do you want to find an automotive shop to help you choose the appropriate product for your car? You can head to your favourite search engine and type in something like “car rustproofing near me” or “rustproofing near me”.
