The short answer is no, Fluid Film does not generally need to be mixed before spraying, provided it’s stored and handled correctly. However, temperature fluctuations can affect its consistency, potentially necessitating gentle warming or agitation to achieve optimal sprayability. This article provides a comprehensive guide to understanding Fluid Film, its properties, and best practices for spraying, ensuring you get the best possible results for rust and corrosion protection.
Understanding Fluid Film
Fluid Film is a unique, non-toxic rust and corrosion preventative that has been used for decades in various industries, from marine and automotive to agriculture and aviation. Its lanolin-based formula provides a durable, self-healing barrier that protects metal surfaces from the damaging effects of moisture, salt, and other corrosive elements. Understanding its composition and properties is crucial for successful application.
The Composition of Fluid Film
Fluid Film is primarily composed of refined wool wax, also known as lanolin, derived from sheep’s wool. This natural ingredient gives Fluid Film its unique ability to penetrate and adhere to metal surfaces, displacing moisture and preventing rust formation. The specific formula also includes mineral oils and other additives that contribute to its overall performance and sprayability. Unlike many petroleum-based rust preventatives, Fluid Film remains semi-fluid, allowing it to creep into tight spaces and provide long-lasting protection.
Temperature Sensitivity
A key characteristic of Fluid Film is its temperature sensitivity. In colder temperatures, Fluid Film can become thicker and more viscous, making it more difficult to spray effectively. Conversely, in warmer temperatures, it becomes more fluid and easier to apply. This characteristic is important to consider when preparing Fluid Film for spraying, particularly in environments with fluctuating temperatures. While it won’t necessarily need to be mixed, its consistency may require adjustment.
Preparing Fluid Film for Spraying
While mixing isn’t typically required, certain preparation steps can significantly improve the spraying process and the overall effectiveness of Fluid Film.
Storage Considerations
Proper storage is essential for maintaining the quality and sprayability of Fluid Film. It should be stored in a cool, dry place, away from direct sunlight and extreme temperatures. Ideally, the storage temperature should be between 60°F and 80°F (15°C and 27°C). Storing Fluid Film in extremely cold temperatures can cause it to thicken, making it difficult to spray, while excessive heat can degrade its properties.
Warming Techniques
If Fluid Film has been stored in a cold environment, it may be necessary to warm it slightly before spraying. This can be achieved by placing the container in a warm room or using a water bath. Never use direct heat sources, such as open flames or heat guns, as this can damage the product and create a fire hazard. A safe and effective method is to submerge the container in a bucket of warm (not hot) water for a period of time, checking the consistency periodically.
Agitation and Stirring (If Necessary)
While not typically necessary, gentle agitation or stirring can help to ensure a uniform consistency, especially if the Fluid Film has been stored for an extended period or has experienced temperature fluctuations. Use a clean, non-reactive tool, such as a wooden or plastic stick, to stir the product gently. Avoid vigorous mixing, as this can introduce air bubbles, which can negatively impact the spraying process. If you observe separation of the oil and solids, a gentle stir will reincorporate them.
Spraying Techniques for Optimal Results
The effectiveness of Fluid Film relies not only on its quality but also on the technique used to apply it.
Choosing the Right Sprayer
Selecting the appropriate sprayer is crucial for achieving a consistent and even application. Options range from aerosol cans for small, localized applications to professional-grade spray guns for larger projects. For larger applications, a pressure pot sprayer with a viscosity cup to measure the Fluid Film’s fluidity is recommended. Airless sprayers are also suitable, but proper nozzle selection is important to avoid clogging.
Application Methods
Apply Fluid Film in thin, even coats, overlapping each pass slightly. This will ensure complete coverage and prevent pooling or dripping. Focus on areas prone to rust and corrosion, such as seams, welds, and undercarriage components. Avoid applying Fluid Film to brake components or exhaust systems, as this can create safety hazards. Multiple thin coats are always better than one thick coat, allowing for better penetration and adhesion.
Safety Precautions
Always wear appropriate safety gear when spraying Fluid Film, including eye protection, gloves, and a respirator. Ensure adequate ventilation in the work area to avoid inhaling fumes. Avoid contact with skin and clothing. Refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
Frequently Asked Questions (FAQs)
Here are 12 frequently asked questions to further clarify the process of spraying Fluid Film:
1. Can I spray Fluid Film directly from the can without any preparation?
Generally, yes. However, if the can feels cold to the touch, allow it to warm up to room temperature for easier spraying.
2. What is the ideal temperature for spraying Fluid Film?
The ideal temperature range is between 60°F and 80°F (15°C and 27°C).
3. What type of sprayer is best for applying Fluid Film to a vehicle’s undercarriage?
A pressure pot sprayer or airless sprayer with an adjustable nozzle is recommended for even coverage. Many also use aerosol cans for touch-up applications.
4. How many coats of Fluid Film should I apply?
One or two thin, even coats are generally sufficient for most applications. Avoid applying excessive amounts that can lead to dripping.
5. Can I apply Fluid Film over existing rust?
Yes, Fluid Film can penetrate and encapsulate existing rust, preventing further corrosion. However, loose or flaking rust should be removed prior to application for optimal results.
6. How long does Fluid Film take to dry?
Fluid Film does not completely dry; it remains semi-fluid. This allows it to creep and provide ongoing protection.
7. Will Fluid Film damage rubber or plastic components?
Fluid Film is generally safe for use on rubber and plastic, but it’s always best to test a small, inconspicuous area first to ensure compatibility.
8. How often should I reapply Fluid Film?
Reapplication frequency depends on the environment and usage. In harsh environments with heavy salt exposure, annual or bi-annual applications are recommended.
9. Can I paint over Fluid Film?
Painting over Fluid Film is not recommended as it can interfere with adhesion. If painting is necessary, the Fluid Film should be thoroughly removed first.
10. Is Fluid Film safe for use around plants and animals?
While Fluid Film is non-toxic, it’s best to avoid direct contact with plants and animals.
11. How do I clean up Fluid Film after application?
Mineral spirits or degreasers can be used to clean up Fluid Film residue.
12. Can I use Fluid Film on electrical connections?
Yes, Fluid Film can be used on electrical connections to prevent corrosion, but use sparingly and avoid over-application.
By understanding Fluid Film’s properties, properly preparing it for spraying, and following best practices for application, you can ensure long-lasting protection against rust and corrosion. Remember to always prioritize safety and consult the product’s MSDS for detailed information.
