Fluid Film Undercoating –
Rust Protection That Works

Fluid Film is a non-toxic, wool-wax-based rust inhibitor that penetrates deep into metal surfaces, displacing moisture and forming a long-lasting protective barrier. Unlike traditional undercoating, Fluid Film never hardens, crack, or traps moisture — which means no rust underneath the coating.

​

​What It Does:
   •    Stops existing rust in its tracks
   •    Prevents new corrosion from forming
   •    Lubricates and protects suspension, brake lines, frame, and body seams
   •    Stays active year-round — won’t wash off in the rain or snow
   •    Safe for paint, rubber, wiring, and plastics

​

Why It Matters:

Here on Long Island, winter road salt, ocean air, and humidity are a recipe for corrosion. Rust eats away at the underbody, frame, brake lines, and even fuel systems — costing thousands in repairs or destroying a vehicle before its time. A Fluid Film application helps extend your vehicle’s life and maintain its resale value.
