Fluid Film Vs Traditional Undercoating
Fluid Film and traditional undercoating serve to protect vehicle undercarriages from rust and corrosion. Both products aim to extend the lifespan of metal parts exposed to moisture and road salts. Fluid Film uses a lanolin-based formula, which differs from the wax or asphalt bases typical in traditional undercoatings. These differences affect how each product performs in real-world conditions.
Self-healing And Penetration Benefits
Fluid Film offers a self-healing property. It flows into cracks and crevices, sealing them effectively. This prevents rust from forming under the coating. Traditional undercoating tends to harden and crack over time. It does not penetrate as deeply into metal surfaces. Fluid Film’s lanolin base stays soft and flexible, allowing ongoing protection.
Durability And Abrasion Resistance
Traditional undercoating creates a tough, thick barrier. It resists abrasion from rocks and debris well. Fluid Film is softer and more oily, offering less abrasion resistance. It wears off easier under heavy mechanical stress. However, Fluid Film’s ability to remain flexible reduces cracking and flaking, which can expose metal.
Maintenance And Reapplication Needs
Fluid Film requires more frequent reapplication due to its softer nature. It can be reapplied without stripping the old layer, making upkeep easier. Traditional undercoating lasts longer but is harder to touch up. Peeling or damage to traditional coatings may require full removal and reapplication. Fluid Film’s easy maintenance suits users who prefer regular care.
Materials Compatibility
Materials compatibility is key when using Fluid Film. The product protects metal parts from rust and corrosion. Yet, it can affect some non-metal materials. Knowing which materials react helps avoid damage. This section covers paints, plastics, rubber, and electrical connections.
Apply Fluid Film carefully to keep all parts safe. Some materials need extra attention to prevent swelling, slipping, or failure.
Paints And Modern Plastics
Fluid Film is safe for most paints. It does not cause peeling or fading. Modern plastics usually resist the product well. They do not swell or degrade easily. Still, test on a small area first. Some specialty plastics may react differently. Avoid prolonged soaking of painted or plastic surfaces.
Older Rubber Compounds
Older rubber can be sensitive to Fluid Film. Non-oil-resistant rubber may swell or soften. This leads to cracks or failure. Avoid spraying bushings, hoses, and seals made from older rubber. Newer rubber compounds are usually safe. Use caution around any rubber parts that show wear or age.
Electrical Connections Safety
Fluid Film protects metal terminals from corrosion. It helps keep electrical connections clean. Avoid spraying exposed or delicate electronics. Lubrication can cause shorts or malfunctions. Use a brush or cloth for precise application. Keep fluid away from circuit boards and sensors.
