Fluid Film 1 Gallon Rust Inhibitor Can – Lanolin-Based Undercoating, Long-Lasting Corrosion Protection

Engineered from refined oils and wool-wax derivatives, Fluid Film is a thick, tacky liquid that clings to metal surfaces instead of drying out. Trusted for decades in marine and industrial environments, this formulation protects underbodies, farm machinery, marine hardware, and any exposed metal against salt, moisture, and industrial contaminants. It also lubricates moving parts and can loosen stuck fasteners by seeping into threads and crevices.

How will Fluid Film protect my vehicle’s undercarriage?

Applied to frame rails, suspension components, and seams, Fluid Film creates a moisture-displacing barrier that reduces the electrochemical conditions that cause rust. Because it is solvent-free and remains pliable, the coating does not crack or flake away with road vibration or temperature changes.

• Penetrates seams and seams—coats hidden surfaces where rust often starts
• Leaves a lasting, non-drying film that resists washout and salt
• Safe for welds and paints when applied per instructions

Can I use this on moving parts and frozen bolts?

Yes — Fluid Film acts as both a corrosion inhibitor and a lubricant, so it helps free seized nuts, bolts, and hinges while reducing wear. Its creeping action gets into tight threads to loosen rusted fasteners without aggressive solvents that can evaporate.

• Reduces friction on hinges, cables, and linkages
• Penetrates stuck hardware to ease removal and maintenance
• Doesn’t evaporate, so lubrication remains effective over time

Is Fluid Film safe to use around paint, rubber, and electronics?

Fluid Film is formulated to be gentle compared with solvent-based products, and it will not dry out or rapidly evaporate. While generally safe, avoid excessive application on painted surfaces, electrical connectors, or delicate rubber seals; wipe away overspray and follow product handling guidance.

• Lanolin-based, low-toxicity formulation—safer than many solvent sprays
• Wipe off any excess from painted or cosmetic surfaces after application
• Avoid direct application to exposed electronic contacts unless specified

How should I apply and maintain this rust inhibitor?

Apply Fluid Film with a brush, spray rig, or drip can to a clean, dry surface for best adhesion. Reapply periodically after heavy exposure to salt, road grime, or industrial atmospheres; inspect coated areas annually and touch up as needed to preserve continuous coverage.

• Clean loose rust and heavy contaminants before application
• Use brushes, spray attachments, or drip cans for even coverage
• Recoat after thorough washing or seasonal wear for ongoing protection

Who is this for: Fluid Film 1 gallon is intended for vehicle owners, fleet managers, marine operators, and maintenance technicians who need a durable, non-drying corrosion protector and lubricant. It’s ideal for cars, trucks, tractors, snow blowers, mowers, trailers, buses, and industrial equipment exposed to moisture, salt, and harsh environments—any situation where long-lasting rust control and ease of maintenance matter.
