Lear Chemicals 20004 Corrosion Block Anti-Corrosion Treatment 1 Gallon

Lear Chemicals 20004 Corrosion Block is a professional-grade anti-corrosion treatment designed to protect metal surfaces and electronics from moisture, salt, and environmental damage. This clear, ultra-thin fluid film creates a non-greasy atmospheric barrier that shields base metals without trapping moisture or leaving residue.

Key Features:

• Approved for use on all metals and electronic components
• Safe to spray directly into electrical connections to prevent corrosion-induced failures
• Chemically neutralizes the corrosive effects of road salt and other contaminants
• Remains active for up to 12 months of continuous protection
• Non-flammable, non-toxic formula contains no solids
• Will not dry out, crack, or trap moisture beneath the protective layer
• Safe for use on most surfaces including painted finishes and plastics (keep off brakes and rotors)

Ideal for automotive, marine, powersports, and industrial applications where corrosion protection is critical. This 1 gallon (4 liter) bottle provides extended coverage for vehicles, equipment, and machinery exposed to harsh environments, coastal conditions, or winter road salt.
