Fluid Film Black Non-Aerosol Corrosion Protector 1 Gallon — Long-Lasting Lubricant & Rust Barrier

Fluid Film Black is a non‑aerosol, wool‑wax based corrosion protector and penetrant that lubricates moving parts and restores a black protective coating to metal surfaces.

Designed for marine, automotive underbody, snow‑handling equipment and general maintenance, this one‑gallon concentrate delivers a thick, wet barrier that seeps into seams and crevices to displace water and slow rust progression. Its solvent‑free formula clings to metal, reduces friction on hinges and linkages, and gives chassis or components a renewed black finish without flammable carriers.

How does Fluid Film Black stop corrosion on vehicles and marine gear?

The product forms a tenacious, oily layer that migrates into joints and voids, creating a moisture‑resistant seal that helps protect metal from salts, brines and damp conditions. Regular application replaces lost lubrication and covers exposed metal to limit further oxidation.

• Thixotropic gel and liquid that adheres to vertical and horizontal surfaces
• Penetrates seams and displaces water for longer on‑metal protection
• Restores a black appearance to treated areas while masking surface rust

Can I use Fluid Film Black on moving parts and latch mechanisms?

Yes — the formula doubles as a penetrant and lubricant, reducing wear on hinges, locks, linkages and exposed bearings while loosening seized fasteners. Because it contains no solvents or flammable carriers, it is safer for regular maintenance tasks in workshops and field settings.

• Lubricates hinges, shackles, pivots and threaded connections
• Penetrant action helps free corroded bolts and frozen parts
• Non‑solvent base minimizes drying and keeps parts lubricated longer

What surfaces and industries is this gallon suitable for?

Fluid Film Black is formulated for all metals and commonly used across marine, automotive, agricultural and industrial applications. It’s effective on underbodies, trailer frames, farm tools, deck hardware and utility equipment exposed to salt or moisture.

• Automotive undercoating and snow‑handling vehicles
• Boat hardware, trailers and marine fittings
• Farm machinery, gates, locks and industrial plant equipment

How should I apply and maintain coating performance?

Apply with a brush, roller or pump sprayer designed for viscous fluids; allow the wet film to flow into seams and recesses. Reapplication intervals depend on exposure — inspect annually or after heavy salt exposure and touch up as needed to maintain continuous coverage.

• Brush or spray for even coverage; brush for seams and hard‑to‑reach areas
• Wipe excess drip but keep a continuous wet film where protection is needed
• Inspect and reapply after winter seasons or prolonged salt exposure

Who this is for: Fluid Film Black 1 gallon is aimed at owners and technicians who maintain boats, trucks, trailers, snow‑handling vehicles, farm equipment and industrial assets that face wet, salty, or corrosive conditions. It fits professionals who need a non‑flammable, long‑lasting coating for large areas, and do‑it‑yourselfers wanting a reliable corrosion control product that doubles as a penetrant and lubricant.
