Fluid Film 1 Gallon Rust Inhibitor & Undercoating — Lanolin-Based, Long‑Lasting Corrosion Protection

Fluid Film 1 gallon is a solvent-free, lanolin-based rust inhibitor and lubricant designed to protect metal surfaces and free up seized parts for long-term corrosion control.

Originally developed for harsh marine environments, Fluid Film combines processed wool-wax, refined oils, and advanced additives to create a thick, clingy coating that displaces water, wets metal deeply, and resists drying out. It works as both a protective undercoating for vehicles and as a maintenance lubricant for hinges, bolts, shafts, and moving parts. Because it’s free of solvents and based on lanolin, the product remains tacky and effective for extended periods, making it useful across automotive, agricultural, industrial, and household applications.

How will Fluid Film protect my vehicle’s underbody?

Applied to frame members, wheel wells, and suspension components, Fluid Film forms a durable film that seals metal against moisture and road salts. Its thixotropic nature allows it to cling vertically on underbodies without sagging while penetrating seams and crevices to prevent hidden corrosion.

• Displaces water and salt to reduce electrochemical corrosion
• Clings to vertical surfaces for long-lasting coverage
• Penetrates seams, welds, and hard-to-reach areas
• Suitable as a preventive undercoating before winter or storage

Can Fluid Film free seized or rusted parts?

Yes—Fluid Film’s penetrating lubricants soak into corroded threads and joints to loosen rusted nuts, bolts, and linkages. Regular application eases maintenance tasks and helps restore movement to frozen mechanisms without harsh solvents.

• Penetrates rust to lubricate stuck fasteners
• Restores motion to hinges, shafts, and pivots
• Reduces torque needed to remove corroded components
• Safe on most metals when used as directed

Is Fluid Film safe to use and environmentally considerate?

Fluid Film is lanolin-based and formulated without solvents, which helps it remain soft and effective without drying into brittle residues. While not a food product, its non-toxic composition and long service life reduce the need for frequent reapplication, lowering waste.

• Solvent-free formula that won’t evaporate away
• Lanolin-based and used widely in marine and industrial settings
• Reduces repeat applications compared to short-lived coatings
• Follow local disposal and application guidelines for best practice

How should I apply and maintain Fluid Film for best results?

Application methods include brush, spray, or drip—with a one-gallon can ideal for workshop refills or larger projects. Clean heavily soiled or flaky surfaces first; then apply an even coat and allow it to settle into seams and crevices. Reapplication frequency depends on exposure, but one thorough treatment typically lasts for many months under normal conditions.

• Clean loose rust and heavy contaminants before applying
• Use a brush, pump sprayer, or pressure sprayer for broad coverage
• Apply generously to seams, fasteners, and hidden cavities
• Inspect annually or after severe exposure and touch up as needed

Who is this for? Fluid Film 1 gallon is aimed at vehicle owners, fleet managers, mechanics, boat owners, farmers, and maintenance professionals who need a dependable, long-lasting rust prevention and penetrating lubricant. It’s especially useful for anyone preparing equipment for winter storage, restoring corroded parts, or protecting metal in salt-prone or marine environments. The one-gallon can offers enough product for multiple vehicles or periodic shop use, making it a practical choice for both home DIYers and professional maintenance crews.

Note: Due to manual filling during manufacturing, occasional residue may appear on the outer can edge or lid. This does not indicate a leak or compromised contents—wipe clean before storage.
