Fluid Film Black Rust and Corrosion Inhibitor 6 Pack - Long Lasting

In this review of the 6 Pack Fluid Film AS11B 11.75 ounce aerosol sprays, the bottom line is simple: this kit is for owners who need long lasting, non-toxic corrosion control for chassis, marine hardware, and exposed metal. The reviewer found the product excels at creating a wet, creeping barrier that displaces water and penetrates seams, making it especially useful for undercoating vehicles and treating salt-exposed parts. The included aerosol format and stickers make application straightforward for DIYers and professional technicians looking for a lubricant that will not dry out.

Key Features

• Corrosion Control: Provides a wet barrier that migrates into seams and coatings to protect metal from salts and brines for extended periods.
• Penetration: A thixotropic formula that will creep into tight joints and penetrate to the base of metals to address existing rust and prevent progression.
• Water Displacement: Wet metal wetting action displaces moisture and inhibits electrochemical corrosion on treated surfaces.
• Long Lasting: Formulated to remain active and will not dry out, offering sustained protection compared with solvent-based sprays.
• Non-Toxic Formula: Made from specially processed wool-wax and refined oils, it is non-toxic and non-hazardous for routine use in repair shops or home garages.
• Lubrication: Acts as a superior lubricant for hinges and moving parts while also delivering corrosion inhibition.

Who It's For

This 6 pack is aimed at automotive owners, fleet managers, boat owners, and snow-handling equipment operators who need to treat multiple components or vehicles. It is helpful where salt, brine, and damp conditions cause accelerated rust and where a product that creeps and penetrates tight seams is preferred.

Those seeking a fast-evaporating solvent spray or a clear finish for visible trim should look elsewhere; Fluid Film Black is a wet, black undercoating meant for protection and restoration of metal appearance rather than a clear dry coat.

Pros & Cons

Pros

• Long lasting, wet barrier that does not dry out, providing durable corrosion protection.
• Excellent penetration and metal wetting to reach seams and base metal beneath surface rust.
• Non-toxic, thixotropic formula suitable for repeated use on vehicles and marine equipment.
• Provides lubrication in addition to rust inhibition for moving parts and chassis components.

Cons

• Leaves a wet black finish, so it is not ideal where a clear or cosmetically invisible coating is required.

Frequently Asked Questions

Is this safe to use on vehicle chassis?
Yes. The product is formulated for chassis and undercoating use and is non-toxic and thixotropic for long lasting protection.

Will it remove existing rust?
It will creep into rusted seams and help protect and stabilize surface rust while restoring a black appearance, but heavy scale may need mechanical removal first.

Does it dry hard or stay tacky?
The formula is designed to remain a wet, non-drying barrier rather than forming a hard, dry film.
