Rustproofing Vehicle Step One
Use CorrosionX to treat electronics including battery terminals, wiring harnesses and fuse busses. CorrosionX sprays as a dense fog to treat internal cavities such as engine compartment, hood cavities, trunk cavities and inside door panels.

Rustproofing Vehicle Step Two
Use CorrosionX XD to treat the underbody and components that are subject to direct splash or spray such as the bottom of the engine, frame, exhaust and suspension components.
