Fluid Film
Fluid Film Rust & Corrosion Protection
Military-grade protection. Lanolin-based. Naturally slippery.
by Fluid Film
Fluid Film is lanolin-based — yes, from sheep wool — and it creates a soft, non-drying barrier that actively displaces moisture and creeps into seams. Used by the US military. Your truck deserves the same.
Fluid Film's lanolin base is what sets it apart from petroleum-based competitors — it's literally refined wool grease, which gives it remarkable surface adhesion and self-healing properties that synthetic films can't match. The military spec rating (MIL-PRF-3150) means it's been validated for long-term storage protection in the harshest environments on earth. The trade-off is that it never sets up dry, so it stays actively slick to the touch indefinitely — which is either a feature or a flaw depending on how you like your protection.
What We Like
- + Lanolin-based formula is all-natural — no synthetics, just pure animal-derived slickness
- + Trusted by the US military for protecting equipment that sees heavy, prolonged action
- + Creeps into every fold and crevice for complete coverage you can feel confident about
- + Non-toxic and solvent-free — safe to handle with bare skin contact
What Could Be Better
- − Stays wet and never fully dries — some people prefer a finish that isn't so slippery
- − Lanolin has a distinctive barnyard scent that's an acquired taste
- − Attracts dust and lint in exposed applications — gets messy in dirty environments
