Fluid Film is a popular lanolin-based rust inhibitor and lubricant widely used on heavy machinery, including excavator undercarriages, to protect against corrosion, reduce wear, and extend component life. Its unique properties provide both rust protection and lubrication, making it suitable for harsh and abrasive environments.
How Fluid Film Works
Fluid Film contains lanolin mixed with corrosion inhibitors and polar agents, which allows it to adhere to metal surfaces and penetrate microscopic crevices. Unlike hard coatings, it remains fluid and self-healing, continuously protecting against moisture and salts while providing lubrication to moving parts.
Benefits of Using Fluid Film
Users report significant reduction in undercarriage rusting and wear with Fluid Film compared to conventional grease or traditional undercoatings. It is favored by operators working in aggressive environments such as salt-prone roads, muddy construction sites, and forestry operations.
One operator noted that after a year of Fluid Film application, previously rust-prone areas were clean and lubricated, with no buildup of abrasive grime common in other products.
Limitations
Fluid Film is an effective, long-lasting protective lubricant for excavator undercarriages, offering superior rust prevention and lubrication in challenging working conditions. Its self-healing, water-repellent properties help maintain component integrity and reduce wear. Proper application and routine recoat schedules ensure optimal protection, making Fluid Film a valuable tool in heavy equipment maintenance.

Benefits of Using Fluid Film
- Rust Prevention: Creates a durable barrier that stops existing rust on contact and prevents new rust formation.
- Lubrication: Penetrates seals and bearings, reducing friction and wear on pins, bushings, and hydraulic cylinders.
- Water Resistance: Provides excellent protection even in wet, muddy, or salty environments by repelling water.
- Long-lasting Protection: Though fluid, it does not easily wash off, often lasting a year or more with reapplication recommended annually.
- Compatibility: Safe for use on most metals, plastics, paints, and electrical components, though caution is advised with some rubber materials.
- Apply to clean, dry surfaces for maximum adhesion.
- Spraying with pressurized equipment helps reach difficult areas such as inside track frames and hydraulic cylinder rods.
- Reapplication frequency varies by environment; high wear or wet conditions require more frequent applications.
- Avoid overlap with rubberized undercoatings that can trap dirt and moisture.
- Check manufacturer recommendations for use on hydraulic cylinders to avoid seal swelling.

Limitations
- Fluid Film can be messy to apply, requiring protective clothing.
- It may soften certain non-oil-resistant rubber components.
- Not a substitute for regular mechanical inspection and maintenance; should be part of a comprehensive undercarriage care routine.
