Marine-Grade Corrosion Inhibitor

FLUID FILM BC is a non-toxic, thixotropic penetrant and lubricant formulated from processed wool-wax and refined petroleum oils. It provides long-lasting corrosion control, metal wetting and water displacement without solvents. The product does not dry out and penetrates to the base of metals for protection in harsh marine, industrial and automotive environments.

Check Compatibility and Surface Prep

Verify that the target materials are compatible with wool-wax-based formulations before application. Ensure surfaces are accessible for the included straw applicator to reach threads, seams or crevices. Confirm that a solvent-free, non-drying film is acceptable for the intended maintenance interval and operating temperature range.

Straw Applicator Enables Precision

The bundled straw attaches to the nozzle for targeted delivery into tight threads, bolt holes and narrow gaps. This reduces overspray on surrounding components and helps salvage heavily corroded or frozen fasteners without disassembly. The accessory directly supports the product’s penetration and water-displacement claims in confined spaces.
