What Is Fluid Film & Why 207 Undercoating Uses It to Protect Your Vehicle

Nov 11, 2025 | News

Introduction to Rust Protection in Maine

If you live in Maine, you know what a tough toll our winters take on vehicles. Between freezing temperatures, snow, and endless applications of road salt, your car’s undercarriage faces constant exposure to corrosive materials. That’s where 207 Undercoating steps in — using Fluid Film, the industry’s leading rust-prevention coating, to keep your vehicle safe, clean, and structurally sound for years.

What Is Fluid Film?

The Origin and Composition of Fluid Film

Fluid Film is a lanolin-based, environmentally friendly rust inhibitor that’s been trusted for over 70 years. Originally developed for the U.S. Navy to protect ships and machinery from saltwater corrosion, it’s now one of the most popular products for automotive undercoating.

Lanolin, derived from sheep’s wool, gives Fluid Film its natural, non-toxic base. It penetrates metal surfaces to create a lasting barrier that displaces moisture, oxygen, and road salt — the three main culprits behind rust.

Why It’s Different from Paint or Tar-Based Undercoatings

Unlike traditional tar or rubberized coatings that dry out and crack, Fluid Film remains soft and self-healing. That means it can creep into seams, joints, and crevices — protecting areas other coatings can’t reach. It doesn’t trap moisture, which is a common issue with other undercoating materials.

How Fluid Film Works to Protect Your Vehicle

The Science Behind Corrosion Prevention

Corrosion happens when metal is exposed to oxygen and moisture. Fluid Film works by creating an impenetrable barrier that prevents oxygen and salt from contacting the metal surface. It’s not just a coating — it’s a living shield that continues to protect, even after months of harsh exposure.

How Fluid Film Stops Salt, Moisture, and Chemicals

Maine’s roads are often treated with calcium chloride and magnesium chloride — both more corrosive than traditional salt. Fluid Film neutralizes their impact by repelling water and sealing off microcracks before rust can take hold.

Longevity and Reapplication Benefits

A single Fluid Film treatment lasts about a year under normal conditions. At 207 Undercoating, we recommend reapplying annually to maintain maximum protection, especially for vehicles exposed to heavy salt or off-road conditions.

Why 207 Undercoating Trusts Fluid Film

Environmentally Friendly and Non-Toxic Properties

At 207 Undercoating, we care about our customers and the environment. Fluid Film contains no solvents or volatile organic compounds (VOCs), making it safe for technicians and eco-friendly for our Maine communities.

Proven Performance in Harsh New England Winters

Fluid Film thrives in the conditions Maine drivers face daily — salt, slush, and temperature swings. It won’t freeze, flake, or chip off like other coatings can.

Customer Satisfaction and Long-Term Vehicle Value

Our customers consistently report smoother rides, cleaner undercarriages, and higher trade-in values after regular applications. Protecting your investment pays off.

Why Every Vehicle in Maine Needs Undercoating

Salt and Calcium Chloride: The Real Threats

Every winter, Maine roads are coated in salt and chemicals to prevent ice buildup. Unfortunately, these same substances eat away at your vehicle’s underbody, brake lines, and suspension components.

The Cost of Not Protecting Your Undercarriage

Replacing corroded parts can cost thousands. An annual undercoating costs far less — and it preserves your vehicle’s lifespan.

Professional Undercoating vs. DIY Rust Prevention

DIY sprays may seem appealing, but professional application ensures full coverage — including those hard-to-reach spots under the frame and wheel wells. 207 Undercoating’s technicians are trained to apply the right amount of product for maximum protection.
