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.
Coat & Protect has the same active ingredients as Rust Check, but is a thicker version. Its viscosity gives it strong resistance to wash and wear and it is used to protect exposed areas of the undercarriage. Unlike traditional undercoating, it is non-drying, meaning it won’t crack or peel. Coat & Protect is also an excellent heavy duty lubricant.
