Crevice areas hidden inside body sections, such as joints, folds, seams and spot welds therein, are the places where corrosion starts and spreads from. Rust Check has the light liquid consistency and the active additives necessary to penetrate deep into and protect the many vulnerable crevices found in today's vehicles.

Rust Check protects metals by displacing moisture and treating the surfaces with highly effective corrosion inhibitors. The corrosion inhibitors form an absorbed (bonded) layer on the metal surfaces. This microscopic layer acts like a series of tiny umbrellas, shielding the surface from water molecules. Just as a car battery will not work without its electrolyte, metal corrosion will not occur if moisture does not contact the metal.

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 vehicle is "Rust Checked" at any of over 250 Rust Check locations.

Accordingly, sealants are best applied to new metals or freshly and thoroughly cleaned and dried metals. If applied to corroded, dirty or wet surfaces, they may not adhere properly to the surface, resulting in a non-intact, unprotective coating. It is particularly difficult to thoroughly clean and dry out the critical crevices and inner body panels areas.

In contrast, Rust Check remains fluid and very mobile and can fill in pores and other voids found in deposits of rust or other corrosion products. Rust Check also provides good penetration into rusted crevices. In cases where crevices are already rusting, Rust Check's deep penetration by capillary action is of even greater importance. The active additives in Rust Check work on a microscopic scale to displace water from metal surfaces and then keep the water from re-contacting the metal.

Rust Check Coat & Protect can adhere to and protect lightly rusted surfaces. It also contains a very high percentage of active additives to "dry" the metal surfaces and keep them dry. Rust Check Coat & Protect also has considerable acid neutralizing capability.

Although Rust Check and Rust Check Coat & Protect will not reverse rusting that has already occurred, they will slow and control its spread.
