(5 PACK) BOESHIELD T-9 Rust & Corrosion Protection and Waterproof Lubrication 12 oz

Boeshield T‑9 delivers long‑lasting waterproof lubrication, rust and corrosion protection, and deep cleaning in a single formula. Its unique blend of solvent and paraffin wax leaves a thin, durable film that shields metal surfaces from moisture, dirt, dust, and mud — keeping your bike running smooth for up to 200 miles.

Designed originally for aerospace use, T‑9 is safe and highly versatile. Beyond bicycle chains, it works on drivetrains, derailleurs, rollers and pins, brake and shift cables, pedal and caliper pivots, seatposts, spoke nipples, and inside frame tubes.

Its non‑conductive formula penetrates deeply to displace moisture, loosen rusted parts, flush out old lubricants, and protect electrical components such as motors, circuits, ignitions, and connectors.

Despite its strong performance, T‑9 is safe on paint, plastic, rubber, fiberglass, and vinyl, and the company states it outperforms Teflon‑based products in durability and protection.
