S S100 Engine Brightener Spray for Motorcycle Engines, 2-Pack 4.5 oz — Mist Nozzle, Temperature-Stable

S S100 19200A-02 Engine Brightener is an aerosol formula that restores faded, gray motorcycle engines to a deep factory-black appearance with a fine mist spray for even coverage.

If your bike's engine has lost its original black finish and looks weathered or gray, this compact aerosol from S S100 is formulated to revive that factory look quickly and cleanly. Designed for motorcycle engines and other metal housings, the product is temperature-stable and comes with a misting spray nozzle to reach cooling fins, crevices, and other detailed surfaces without over-application. Sold as a 2-pack of 4.5 oz. cans, it's handy for touch-ups, periodic maintenance, and for preparing a bike for shows or resale.

How do I apply S S100 Engine Brightener for the best result?

Surface prep is essential: remove dirt, oil, and old residue, then allow the engine to dry completely. Hold the can upright, use the misting nozzle from 8–12 inches away, and apply light, even coats to avoid runs or buildup. Allow each coat to dry before adding another to achieve a consistent factory-black finish.

• Clean engine thoroughly; degrease and rinse.
• Dry fully — no moisture before spraying.
• Spray from 8–12 inches with light passes using the misting nozzle.
• Let each coat dry before re-coating for depth control.

Will this hold up to riding conditions and washes?

S S100 Engine Brightener is formulated to be temperature-stable and withstand normal road use and routine cleaning. While it refreshes the appearance and resists common wear from washes and weather, longevity depends on riding conditions and how often the engine is exposed to abrasives or harsh cleaners.

• Temperature-stable formula for engine heat exposure.
• Resists routine washing and light weathering.
• Reapply as part of periodic maintenance for best results.
• Avoid abrasive brushes and harsh chemicals to preserve finish.

What surfaces and areas is the brightener safe for?

It's intended for painted and coated engine components and metal housings that originally had a black finish. The fine mist nozzle helps reach cooling fins, bolts, and recessed areas, but avoid using on hot surfaces or directly on sensitive parts like brake components, exposed wiring, or unsealed bearings.

• Best for painted/coated engine casings and housings.
• Effective in cooling fins, crevices, and detailed surfaces.
• Do not apply to hot engines or moving parts.
• Avoid contact with brakes, sensors, and electrical connectors.

Who is this for: S S100 19200A-02 Engine Brightener is aimed at motorcycle owners, restorers, and detailers who want a quick, portable solution to restore a tired black engine finish without disassembly. It's ideal for riders prepping a bike for sale, show entrants needing touch-ups, or anyone who wants to maintain a factory-black look between deeper restorations. The two 4.5 oz. cans offer enough product for multiple touch-ups and small projects, and the misting spray nozzle makes it approachable for users who prefer a controlled, even application.
