Performance Suspension Technology - Rust Prevention

Cavity Coater is a one-step, super-penetrating corrosion inhibiting coating (CIC) for long term protection on all metal surfaces. Provides a self healing film which renders over 4000+ hours of salt spray protection...over 4 times the protection of conventional cavity waxes. Using Cavity Coater gives long lasting protection for those hard to reach enclosed cavities such as rocker panels, boxed frames, inside doors & fenders, deck lids, tailgates...and more.

RPM is a revolutionary formula that is easy to apply and will leave bare metal components such as tie rod ends, brake drums and control arm shafts rust free for years to come. No front end rebuild or restoration is complete without RPM.
