Learn how to protect your metal gear from rust and corrosion using XF-7 Corrosion Inhibitor. This guide covers preparation, application, and maintenance for long-lasting protection.
Quick answer
Use XF-7 Corrosion Inhibitor to clean, protect, and prevent rust on metal gear. Apply it after cleaning to create a waterproof, heat-resistant barrier that stays in place even under heavy use.
Why corrosion matters for your gear
Metal parts on bags, pouches, and tools can rust when exposed to moisture, salt, or sweat. Once corrosion starts, it weakens zippers, buckles, and hardware. XF-7 Corrosion Inhibitor is a waterproof grease that stops that process and prevents new rust from forming. It stays put even in heat up to 500°F, so it works on firearms, knives, and outdoor tools that see heavy use.
When not to use XF-7
XF-7 is a grease, not a solvent or paint. It won't remove heavy rust that has already pitted the metal. For deep rust, you need abrasive cleaning first. Also, it leaves a protective film that may attract dust in dry, sandy environments. If you store gear in a clean, dry case, this is less of an issue.
How to remove and prevent gear corrosion with XF-7
- Clean the metal surface: Wipe away dirt, oil, and loose rust with a dry cloth or a brush. For stubborn rust, use fine steel wool or a rust eraser. The surface must be clean and dry before applying XF-7. Common mistake: applying grease over dirty or wet metal traps moisture and makes corrosion worse. Always degrease and dry the part first.
- Apply XF-7 Corrosion Inhibitor: Squeeze a small amount onto the metal surface or a clean cloth. Rub it evenly over the area, making sure to cover all exposed metal. For moving parts like zippers or hinges, work the grease into the joints. Common mistake: using too much. A thin film is enough; excess just attracts dirt. Less is more – a thin, even coat provides full protection.
- Let it set and test the action: Allow the grease to settle for a minute. Then operate the part – open a zipper, rotate a buckle, or cycle a firearm action – to distribute the lubricant evenly. Wipe off any excess that squeezes out. Common mistake: skipping the test step. You need to confirm the protection reaches all friction points. Cycle the part to work the grease into tight spots.
- Store and reapply as needed: Store your gear in a dry place. XF-7 stays effective for months, but reapply after heavy use, washing, or exposure to salt water. Check metal parts every few months for signs of moisture. Common mistake: assuming one application lasts forever. High-use items need periodic touch-ups. Reapply after exposure to water or heavy wear.
