Frequently Asked Questions, Answered

What is Rust Check?

Rust Check is a light liquid oil-based product with active corrosion inhibitors. Its main function is to penetrate into crevices, displace existing moisture, and then keep moisture from re-entering. Without moisture, corrosion cannot occur.

What is Coat and Protect?

Amber Coat & Protect is a thicker version of Rust Check (aka Dripless), with the same active ingredients. Its thickness gives it good wash and wear resistance. The main function of Coat & Protect is to protect exposed areas of the undercarriage. Unlike traditional undercoating, Coat & Protect is non-drying, so it won't crack or peel. Coat & Protect also is an excellent heavy duty lubricant.

Does Dripless mean it doesn't drip?

No. Dripless is our Amber Coat & Protect product. It is a thicker product and doesn't drip off your frame, however the internal panels are treated with our Traditional product. Typically this is the dripping you will notice as access product drips out your drain holes. If dripping is a major issue, ask staff about options.

What is the Black Coat & Protect?

Rust Check Black Coat & Protect provides the required protection for exposed areas of your vehicle's undercarriage. The Black Coat is formulated as a premium undercarriage treatment that forms adherent and wash resistant, self-healing protective films that will not crack or peel. The Black Coat also provides excellent undercarriage appearance, and lubricates as it protect.

How long does an application take?

A typical application takes approximately 1 hour.

Will Rust Check void any new car factory warranties?

NO. Rust Check is an aftermarket product, but it will not void any factory warranties issued by the manufacturer.

What is your warranty?

Rust Check offers lifetime, annually renewable warranties to all cars less than one model year and to qualified cars up to five model years old. This is not a money-back warranty - if a vehicle rusts from the inside out, we will pay for the repairs in accordance with the Warranty Certificate The warranty is transferable, and has no mileage restrictions. NOTE: The warranty is annually renewed when your car is "Rust Checked"

What kind of rust protection should I get for my car?

Rust Check has a long history of successful automobile rust protection. Time Tested and Proven since 1973. Recipient of the 1997 Consumers Choice award for Automobile Rust Proofing Service. Effective on both new and used vehicles. Complete annual re-applications, not just touch-ups. Lifetime, annually renewable warranty - as long as Rust Check continues to be applied, it will continue to protect your vehicle.

Why do I need additional rust protection for my car?

Data from a 1995 DesRosiers Survey indicated that without additional rust protection, cars were pretty much certain to show some rust after 6 to 8 years. The survey indicated that with additional rust protection, cars were almost certain not to show any rust even after 13+ years. Additional rust protection will protect your car's resale value or its residual value when coming off a lease.

Does your product drip?

Rust Check is a thin liquid product designed to penetrate deep down into the crevices of a vehicle. In order to access these areas you may experience occasional dripage. There is very little dripage from our undercarriage application when Coat and Protect is applied.

Do you drill holes?

A few holes may be required in order to access body cavities that factory design has not allowed for. These holes are approximately 1/2 inch in size, and enable even and complete coverage of each panel. We do offer "no hole" treatments, ask us for more details.

No one time application lasts forever. "Permanent" rust protectants typically offer a warranty for a maximum for 10 years. This means such systems can only delay serious rusting. Furthermore, annual inspections or touch-ups typically are required to keep the warranty valid, so there is no difference as far as the "convenience" factor is concerned. Rust Check maintains a high level of corrosion protection by completely retreating your vehicle very year. By doing so, Rust Check can offer a lifetime warranty - we will protect your car "forever".

If it rains or snows will the treatment be effective?

Yes. Rust Check displaces moisture, so it can be applied in any weather, and at any time of the year. NOTE TO SOMMER: Update to include that Rust Check bonds to the metal instead of sitting on top of the water like most other products.

Is there anything I should do to prepare my car for process?

To prepare a vehicle for application all we ask is that the vehicle is clean and the trunk is empty. In some cases a quick car wash is also recomended, but avoid under carrage wax sprays for best results. These steps will help the technician stay within the estimated 1 hour time limit.

My car already has a different type of rustproofing applied on it, will Rust Check be as efficient in this case?

Yes. In cases where an alternate product such as wax or tar based treatment has been used prior to Rust Check, those products typically show signs of failure after time. Drying, cracking and eventual flaking generally occur allowing moisture to creep beneath the coating, causing rust. Rust Check if applied over these coating also creeps in behind and pushes out the moisture, thus attacking the spread of rust.

Are floor boards covered under your warranty?

Floor boards on vehicles are not covered under the terms of the warranty. This is due to the fact that the majority of floor boards rust from the inside below the carpet, where Rust Check is not applied. A simple precaution to this problem is the use of pantsaver floor mats, which catch the water, snow and ice that is brought into the vehicle by the occupants. This small investment could eventually save you hundreds of dollars in repair bills.

Are there benefits to using touch-up paint?

Stone chips are a major cause of surface rust on vehicles. The use of touch-up paint greatly reduces the risk of paint blisters caused by chips. By taking care of a small problem when it is noticed, it could save you hundreds of dollars in eventual body work costs.
