Rust Proof is a heavy duty corrosion preventative coating formulated to comply with AS2662, Part 1 - 1983 - Corrosion Inhibition (Rust Proofing) - Motor Vehicles. It is designed to inhibit the formation of rust in internal box sections, door cavities, sills and pillars of motor vehicles. Rust Proof dries to a soft brown waxy protective coating. It is rheology controlled to give excellent atomisation with a fogging attachment, particularly with low pressure systems, and has excellent seam penetration with negligible sag and run.
