Ontario winters are hard on cars. Road salt, slush, moisture and repeated freeze-thaw cycles create the right conditions for corrosion, especially underneath your vehicle and in areas you don’t normally see.
Rust often starts in hidden, moisture-trapping areas like inside door panels, rocker panels, and the undercarriage, before breaking through the paint. By the time rust becomes visible, corrosion may already have been developing underneath the surface.
That’s why fall is a smart time to rust proof your vehicle. Applying rust protection before winter road conditions begin gives your vehicle an added layer of protection before it is regularly exposed to salt and moisture.
What Is Rust Proofing?
Rust proofing is a preventative treatment that adds a protective coating to metal surfaces that are vulnerable to moisture and road salt.
Unlike wax, which is applied to your vehicle’s painted exterior, rust proofing is designed to protect areas such as the underbody, seams, crevices and other hard-to-reach metal surfaces. It doesn’t make a vehicle completely rust-proof or reverse existing corrosion, but it can help protect against the conditions that cause rust and slow its progression.


Why Rust Proof Before Winter?
Think of rust proofing as getting ahead of the problem.
Once winter arrives, your vehicle is repeatedly exposed to salty water, road spray and moisture. Applying rust protection in the fall means those vulnerable areas have an additional layer of protection before the harshest driving conditions begin.
What Is No-Drip Rust Proofing?
Older, traditional oil sprays are messy and can leave permanent stains all over your driveway. Our No-Drip Oil Spray Rust Protection gives you the exact same heavy-duty, deep-penetrating defense but without the annoying dripping.
The treatment is applied to areas where moisture and salt can collect, including seams, crevices and hard-to-reach areas. The formula adheres to the metal and provides ongoing protection without the mess associated with heavier dripping treatments.
The Benefits of No-Drip Rust Protection
- Minimizes dripping and mess after application
- Helps protect against road salt and moisture
- Reaches seams and hard-to-access areas
- Provides a protective coating on vulnerable metal surfaces


When Should You Rust Proof Your Car?
Rust proofing is preventative maintenance. The goal is to protect your vehicle before corrosion becomes a visible or expensive problem.
Rust proofing can be done throughout the year, but we recommend getting the treatment done in the fall, before regular winter driving begins. Fall temperatures are still moderate and allow the rust-proofing treatment to flow and penetrate into tight seams, welds and other hard-to-reach areas. It also gives you the opportunity to apply the treatment before road salt and heavy winter moisture build up on your vehicle, providing a clean surface for the treatment to bond to.
If you haven’t rust proofed your car yet this year, getting it done now ahead of winter is highly recommended to stop hidden corrosion from accelerating.
