Fluid Film Corrosion Inhibitor (5 Gallon Amber) Review: A Deep Dive into Rust Prevention

Fluid Film is a well-known name in the world of corrosion inhibitors, and their 5-gallon amber container is a popular choice for professional and serious DIY users. This review will delve into the features, benefits, and drawbacks of this product to help you decide if it's the right solution for your rust prevention needs.

What is Fluid Film Corrosion Inhibitor?

Fluid Film is a lanolin-based corrosion inhibitor designed to protect metal surfaces from rust and corrosion. Unlike many other rust preventatives, it's not a paint or coating; instead, it penetrates the surface and forms a protective barrier that resists moisture, salt, and other corrosive elements. It's particularly effective in harsh environments and is used widely by vehicle enthusiasts, boat owners, and those working with heavy machinery.

This specific 5-gallon amber container is ideal for larger projects, offering excellent value for money compared to smaller sizes. The amber color helps to distinguish it from other fluids and provides some UV protection.

Key Features of Fluid Film 5 Gallon Amber Container

  • 5-Gallon Capacity: Provides a large quantity for multiple applications or large-scale projects.
  • Lanolin-Based Formula: Penetrates surfaces, providing long-lasting protection.
  • Water Displacing: Repels moisture, preventing rust formation.
  • Amber Color: Helps with identification and offers some UV protection.
  • Versatile Application: Suitable for various surfaces, including metal, wood, and even some plastics.

Pros of Fluid Film Corrosion Inhibitor

  • Exceptional Corrosion Protection: Fluid Film provides superior rust prevention, outperforming many competitive products in long-term testing, even in extremely harsh conditions.
  • Excellent Penetration: The lanolin-based formula easily penetrates to protect even hard-to-reach areas and existing rust, slowing its progression.
  • Long-Lasting Protection: A single application offers protection for an extended period, reducing the frequency of reapplication compared to other rust inhibitors.
  • Environmentally Friendly: Unlike some harsh chemical rust removers, Fluid Film is considered to be relatively environmentally friendly.
  • Cost-Effective for Large Projects: The 5-gallon size offers significant cost savings compared to purchasing multiple smaller containers.

Cons of Fluid Film Corrosion Inhibitor

  • Application Can Be Messy: Working with a viscous product like Fluid Film requires care to avoid spills and over-application.
  • Strong Odor: The product has a noticeable, lanolin-based odor that can be strong for some users. Adequate ventilation is necessary during application.

Who Should Buy Fluid Film Corrosion Inhibitor?

This product is a great choice for individuals and professionals who need a robust and long-lasting solution for preventing rust and corrosion. It is particularly suitable for:

  • Automotive enthusiasts: Protecting classic cars, undercarriages, and chassis components.
  • Boat owners: Safeguarding hulls, engines, and other marine equipment from saltwater corrosion.
  • Heavy equipment operators: Protecting machinery from the elements and harsh working conditions.
  • Farmers and ranchers: Protecting equipment exposed to the elements and moisture.
  • DIY homeowners: Preserving tools, metal structures, and other assets from rust.
The 5-gallon size is especially beneficial for those with larger projects or who need to treat multiple items regularly. For smaller applications, smaller sized containers are available, which avoids unnecessary waste.

Comparison with Competitors

Fluid Film competes with various corrosion inhibitors, including Boeshield T-9 and Rust-Oleum Rust Preventative. While other products offer similar rust protection, Fluid Film's lanolin-based formula often stands out for its superior penetration and long-term effectiveness in damp and salt-laden conditions. However, the price point is notably higher than many competing products.

Frequently Asked Questions (FAQs)

Q: How long does Fluid Film last?

A: The lifespan of Fluid Film depends on the application and environmental conditions. It can last for several months to a year or more in many cases. Reapplication is recommended as needed depending on the level of exposure to the elements.

Q: Is Fluid Film flammable?

A: Fluid Film is not considered highly flammable, but it's still recommended to avoid open flames during application and storage.

Q: Can Fluid Film be used on painted surfaces?

A: It's best to test Fluid Film on a small, inconspicuous area of a painted surface first, as it may affect some types of paint.

Conclusion

Fluid Film's 5-gallon amber corrosion inhibitor offers excellent rust prevention capabilities thanks to its unique lanolin-based formula and impressive penetration qualities. While the cost is a factor, the long-term protection and effectiveness make it a worthwhile investment for many users who require durable rust protection in challenging environments. The application process requires some care due to its viscosity and smell but the results justify the effort for those seeking a top-tier corrosion preventative.

These are a bit of a mixed bag. On one hand, the price is unbeatable and the height increase is exactly what I needed for my commute. On the other hand, the anodizing seems thin and I already have a small scratch from just installing them. Also, the instructions were basically non-existent. If you're on a tight budget they're fine, but if you want something that stays looking new for years, maybe look elsewhere.

Waste of money. One strip was DOA and the other lasted two days before half the LEDs went out. Spend a bit more and get something that actually lasts.

Disappointed. These are way too small for standard stage mics and two of them ripped the second I tried to stretch them over the grill. Spend your money on something more durable.

I really dont get the hype... its just body lotion? The smell is way too strong for me and it gave me a headache. Way over priced for the size of the tube.
