More than just a highly visible blight, rust can rapidly corrode the structural integrity of your vehicle. A single professional application of our exclusive rust blocking formula will protect your new vehicle from inner body rust for life. Perma-Plate's exclusive process even protects your car from environmental hazards that may not be covered under your manufacturer's warranty. Using Rustguard's advanced chemical formula your dealer will permanently seal your vehicle's inner body metal surfaces. By adhering to the interior surfaces of fenders, doors, quarter panels, and other critical areas where trapped moisture from weather and condensation can collect, Rustguard protects areas that would otherwise become a hospitable environment for rust.
