Protecting Your Vehicle’s Underside with Fluid Film: Why It’s Essential


Hey there, off-road enthusiasts! Welcome back to the Mount Zion Offroad blog. Today, we’re diving into a topic that’s absolutely critical for anyone who loves hitting the trails: protecting the underside of your vehicle. Let’s talk about one of the best products on the market for this purpose—Fluid Film.

Why Protect the Underside of Your Vehicle?

Whether you’re a weekend warrior or a hardcore off-road adventurer, or even just driving your vehicle in the elements of winter, your vehicle’s undercarriage takes a beating. From rocky paths and muddy trails to snow-covered roads laden with salt, the underside of your vehicle is exposed to a variety of harsh conditions. This exposure can lead to rust, corrosion, and ultimately, expensive repairs. Protecting this vital area isn’t just about maintaining your vehicle’s appearance—it’s about ensuring its longevity and performance.

Introducing Fluid Film

Fluid Film is a top-tier rust and corrosion prevention product that’s been trusted by professionals and enthusiasts alike. It’s a lanolin-based solution that creates a protective barrier on metal surfaces, preventing rust and corrosion even in the harshest environment.

Benefits of Fluid Film

  1. Long-Lasting Protection: Unlike some coatings that can wear off or break down over time, Fluid Film remains effective for extended periods, providing continuous protection.
  2. Non-Toxic and Eco-Friendly: Fluid Film is made from natural lanolin, making it safe for the environment and for use around your home.
  3. Penetrates and Lubricates: Not only does Fluid Film protect, but it also penetrates existing rust, making it easier to break loose. Plus, it acts as a lubricant, keeping moving parts like suspension components operating smoothly.
  4. Water Resistant: Fluid Film is highly resistant to water, meaning it won’t wash off easily even in wet conditions. This makes it ideal for off-road vehicles that frequently encounter water crossings and muddy trails.



Applying Fluid Film: A Step-by-Step Guide

  1. Clean the Undercarriage: Before applying Fluid Film, thoroughly clean the underside of your vehicle. Remove any dirt, mud, and existing rust. A pressure washer can be very effective for this step.
  2. Dry Completely: Ensure the undercarriage is completely dry. Moisture can interfere with the effectiveness of the application.
  3. Application: Use a sprayer or brush to apply Fluid Film evenly across the entire underside of your vehicle. Pay extra attention to vulnerable areas like seams, welds, and joints where rust is more likely to develop.
  4. Reapply Regularly: For the best protection, we recommend reapplying Fluid Film once or twice a year, depending on how often you take your vehicle off-road and the conditions you encounter.
