Durability matters! That’s why Oil Gard Anti-Rust stands out from the rest. Many automotive professionals—mechanics, auto-body experts, and repair shops—recommend Oil Gard after seeing its long-lasting protection firsthand. Our Formula 2 No-Drip and Classic products hold up exceptionally well, even against Ontario’s toughest weather and road conditions.

We often hear from vehicle owners frustrated with other rust-proofing treatments that fade away within weeks. Unlike thinner, lower-viscosity options that struggle to stay in place, Oil Gard products are engineered to last a full year with expert application. That’s why so many drivers trust us, and why professionals confidently refer their customers to Oil Gard. We’re grateful for the recommendations and for customers who do their research before choosing the best rust protection!

For maximum protection against rust, we recommend applying Oil Gard products to your vehicle every year.

Vehicles are affected by rust year-round. The time of year you choose to Oil Gard your vehicle will not alter the effectiveness for protecting your vehicle from rust. Most customers prepare for the fall and winter weather and road conditions by visiting Chatham Oil Gard in the fall – which is smart. However, applying Oil Gard in warm weather is just as effective! Warm temperatures cause microscopic pores in metal to open, allowing rust-preventive compounds to penetrate more deeply—similar to how moisturizer absorbs into your skin. No matter when you apply Oil Gard, your vehicle remains protected year-round.

Oil Gard is designed to prevent rust from forming, but if your vehicle already has rust, our Formula 2 No-Drip and Classic products will also help slow its spread

Not at all! Oil Gard is specially formulated to penetrate metal while displacing moisture. It is water-resistant and remains effective even in rainy conditions, so you can confidently have it applied to your vehicle, rain or shine!

No, your warranty will not be void – and we will go over your warranty coverage with you to reassure you! All manufacturers sell rust-proofing packages through their dealerships which are all aftermarket products. No warranty will say that aftermarket rust-proofing will void your warranty, and there is no manufacturer warranty that will guarantee your vehicle will not rust!

Most modern vehicles are designed with factory access points that allow rust-proofing treatments to reach key areas without additional drilling. However, to ensure full coverage—especially in tight spaces and vulnerable seams—your trained Chatham Oil Gard technician may need to create small access points. This ensures the rust-proofing formula penetrates deeply into hidden areas, providing complete and lasting protection.  

After applying the treatment, these access points are sealed with protective caps, leaving a clean and professional finish. If drilling is required for your specific vehicle, our team will walk you through the process. Rest assured, this procedure does not void any manufacturer’s warranty.

Oil Gard offers two rust-proofing formulas, each designed for different needs:

  • Formula 2 No-Drip gradually creeps into seams and crevices without dripping.
  • Oil Gard Classic is a low-drip formula that penetrates more quickly, which may result in some initial dripping after application.


Both formulas provide highly effective, proven rust protection for your vehicle.

Some vehicle parts, such as fenders and hoods, are made from plastic compounds. These do not require rust-proofing. Your Chatham Oil Gard will advise you on which components do and do not need treat

Oil Gard Anti-Rust Canada adheres to a strong standard of advertising accuracy and ethics, refusing to make false claims or blanket statements. The company would like to make consumers aware of false statements being made by our competitors in the market place. One false statement by a competing company claims they have the only product that can be applied in any type of weather and in any season. This leads you to believe all other companies’ products are not able to do this. Oil Gard is specifically formulated to be an Any Time/Any Season/Any Weather product. In fact, we support the efficacy of our product and our service in all weather with our Rain Check guarantee. A second bogus claim by a competitor states they are the ONLY product that contains no solvents and is non-toxic. This is not true. Oil Gard’s proven rust prevention formulas also contain no solvents and are WHMIS certified non-toxic. A further advertising claim makes the conclusive statement that since they are non-toxic, they are “environmentally-friendly.” This is a broad claim and we recommend consumers ask specific questions about the product being offered. What all rust-prevention companies should be is environmentally-responsible: using processes to ensure minimal impact on the environment. Beware the false statement: “If it doesn’t drip it doesn’t work.” This claim is made by competitors who use oil-based products that are blends of non-proprietary substances. They are thin and messy and will drip from your vehicle for weeks, leaving spots of greasy residue on your driveway or in your garage. Oil Gard Formula 2 No-Drip is our best selling rust-prevention treatment – applied to thousands of vehicles every year. It creeps into seams and crevices, actually penetrating the pores of metal. At Oil Gard we believe the best rust prevention product is one that stays on your car or truck.
