Boeshield T-9 Rust & Corrosion Protection and Waterproof Lubricant, 12 oz

Overview

Boeshield T-9 was developed and licensed by The Boeing Company to address a need for high‑performance, long‑lasting metal protection and lubrication. The formulation combines a solvent carrier with a paraffin wax coating to penetrate crevices, displace moisture, and dissolve minor corrosion, leaving a clean, waxy finish that endures. It avoids reliance on Teflon, silicone, fluorocarbons, MEK, or acetone, making it a versatile choice for a range of environments and equipment.

From seafaring yachts and muddy trails to workshop benches and shower stalls, Boeshield T-9 delivers a protective film that supports smooth movement and resistance to moisture. It can be used on engines, wiring, belts, and various metals, safely touching paints, plastics, and vinyl without leaving behind a sticky residue. The product remains nonconductive, reducing concerns about short circuits when used near electrical components.

How it works

The unique carrier travels into metal crevices, displacing moisture and flushing out dirt and old lubricants. As the solvent evaporates, it leaves a thin, durable waxy film that continues to protect and lubricate moving parts. The formula dries to a non‑sticky, water‑repellent coating that stays in place through rain, mud, and spray, yet remains removable with solvent or by re‑spraying if a refresh is needed.

Key characteristics

• Penetrates deep into crevices to displace moisture and loosen rusted parts
• Flushes out dirt and old lubricants for fresh, even lubrication
• Dries to a thin, waxy film that clings to metal for months
• Nonconductive and safe for electronics, paints, plastics, vinyl, and rubber

Versatile uses and benefits

This multi‑surface protector shines in marine, automotive, cycling, and workshop settings. The waxy film provides a durable barrier against moisture while allowing components to move more freely. The formulation helps with wet parts, electrical connections, and fittings that benefit from a light protective coating without a sticky residue.

• Ideal for marine, bicycles, automotive, tools, RVs, and aviation components
• Safe on paints, plastics, vinyl, and other common materials
• Can be refreshed by re‑spraying; removes easily with solvent when needed

How to use

Shake well and spray onto a clean, dry surface. Allow T‑9 to dry to a waxy film. Wipe excess for immediate use, or apply to wet parts and let it permeate before reassembling. Reapply as needed to maintain protection.

What to expect

The resulting film is waterproof and resilient in wet conditions, without a sticky feel that attracts dirt. It won’t wash off in rain or mud, and grime can be rinsed away while the protective coating remains. It is designed to be removable when you choose to refresh or reapply.
