20012 CORROSION BLOCK, AEROSOL 12 OZ

**Corrosion Block (P/N 20012)** is a clean, clear fluid in a convenient aerosol format that actively protects metal using advanced polar bonding chemistry. It penetrates corrosion cells, displacing moisture and saltwater — which are then allowed to evaporate. Once applied, Corrosion Block forms a hydrophobic film that acts as an **“OFF SWITCH” for corrosion**, leaving a long-lasting protective barrier. It is non-conductive, safe for all metals, plastics, and rubber, and ideal for use in aviation, marine, and industrial applications. This 12 oz aerosol can delivers targeted, even coverage — making it perfect for quick treatment of connectors, terminals, avionics, and exposed metal areas. --- ## Applications - Electrical terminals, switches, and connectors - Avionics, lighting systems & harness assemblies - Battery terminals, ground connections & bonding points - Tools, hinges, marine trailers, winches & landing gear - Control cables & exposed metal subject to salt or moisture --- ## Why CJ Aerospace?
