Frequently Asked Questions

Do you have questions about our rust check services? Read the answers we provide to the most common asked questions.

Rust check is a rust protection system with a two product process. It is a light liquid oil-based product which actively inhibits corrosion. Rust check functions by penetrating into crevices to displace existing moisture, and then keep moisture from re-entering – no moisture, no corrosion.

A typical application takes approximately 1 hour.

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

Rust Check offers lifetime, annually renewable warranties to all cars less than one model year and to qualified cars up to three (3) 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”.

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.

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.

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 no dripage from our undercarriage application when Coat and Protect is applied.

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

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.
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.
To prepare a vehicle for application all we ask is that the vehicle is clean and the trunk is empty. If the vehicle is a 4 x 4, it is requested that any mud or heavy build up is pressure washed off prior to bringing the vehicle in. These steps will help the technician stay within the estimated 1 hour time limit.

Yes. Rust Check displaces moisture, so it can be applied in any weather, and at any time of the year.

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.
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.
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.
Certain Japanese built vehicles, namely Chrysler Colts, Toyota Tercels, GLC and, Honda CIVICs, around the area where the rear window wiper assembly is connected to the hatch, has on occasion rusted. To examine this matter a little closer, we spoke with a Honda representative who told us that on a few cars the wiper assembly is installed after the car has been completely assembled and tinted. Consequently, when the hole in the hatch is cut to install the wiper assembly, two problems can arise. The first possible problem is that the cutting OJ used to make the hole in the hatch is dull. This can cause excessive heat as the hole is being cut. The heat separates the paint from the metal, which then allows moisture to condense on the metal under the paint. This moisture causes rust that expands, which explains the paint bubbles and blisters that start in this area. The second problem is, in some cases, the metal isn’t properly protected around the edges where the hole is cut. The exposed metal allows rust to start and spread under the paint. This causes blistering and cracking of the painted surface. Please be aware of these potential problems and, bring them to the owner’s attention if it pertains to his/her vehicle. Direct them back to their local car Dealer or Area Representative.
