Rust Check

Highly Cost-effective Rust Proofing That Outperforms Electronic Modules

Not all rust protection is created equal. Your new vehicle starts off looking beautiful, but moisture, high humidity, road salt and other pollutants start deteriorating it from day one. As vehicles age, it’s critical to maintain them so the body lasts as long as your engine.

At DDF Automotive in Barrie, we offer a variety of rust proofing solutions to suit your lifestyle and car/truck.

We offer Rust Check Barrie, which is an annual oil-based application for vehicles of all ages and also Diamond Kote Barrie which is a permanent-style rust proofing for new vehicles (2 years or less) only.

Rust Protection Process


Rust Inhibitor

There are hidden crevices and folds in the metal of your vehicle that moisture loves to collect in and from there, rust starts to develop. Rust Check Rust Inhibitor is a light oil-based liquid that we spray into all of the body panels using existing or drilled holes. It’s designed to “creep” throughout the panels and soak into the metal, preventing rust effectively from the inside, out.


Coat & Protect

Coat & Protect is a self-healing, non-drying undercarriage treatment. It’s thick like Vaseline so you get an instant layer of protection from your very first treatment. Say no to that thin, drippy stuff. No more “building it up” over the years. It improves the look of the undercarriage not to mention lubricates as it protects.

Car Doctor

Our Philosophy: "Spray it like you own it." For over 22 years now we've been oiling cars and trucks with this philosophy and it's why our customers keep coming back year after year.

Come and experience the DDF difference.

I have an older car in excellent condition, It has never been winter driven, so I wanted to protect it from the typical Barrie winter. DDF accommodated me very well. They did a Rust Check protection treatment and provided me with Weather tech floor liners. My Car is ready!!
