Mercury  Quicksilver – High-Gloss Cowl Finishing Compound | Surface Restoration | Fine Grit | 8M0168837

Overview

Any boater who’s spent time around docks, trailers or tight marina corners knows how easy it is for a cowling to pick up small scuffs and scratches. They’re minor, sure—but they tug at you every time the sun hits them just right. The Quicksilver 8M0168837 High-Gloss Cowl Finishing Compound brings back that clean, deep shine that makes your engine look cared for and ready for the next run. It’s simple to use, satisfying to apply and delivers that “like-new” finish that’s hard not to admire when you’re firing up for a day on the water.

Key Features

• Fine-grit rubbing compound designed to remove minor surface scratches on engine cowls

Engine & Boat Compatibility

This finishing compound is safe for use on:

• All Mercury and Mercury Racing engine cowls, from small portable outboards to high-horsepower models
• Fiberglass, gel coat and painted cowl sections

• Boats stored indoors, outdoors or in harsh saltwater environments where cowl surfaces see regular wear

Performance & Practical Benefits

There’s something deeply satisfying about polishing away the dullness that builds up from long days on the water. This compound starts by gently leveling out light scratches—those faint marks from a dock line, a bump against a piling or a moment of carelessness around the trailer. With slow, steady rubbing, you’ll feel the surface go from slightly gritty to smooth and bright again.

The finish you get isn’t just shinier—it feels tighter, smoother and more protected once you follow up with a good marine wax. That wax locks in the high-gloss look and helps shield your cowl from UV light, salt spray and daily handling. It’s the kind of occasional maintenance that keeps your outboard looking sharp and well cared-for year-round.

This compound is also incredibly easy to control. The fine grit gives you just enough bite to do real work without the risk of damaging the finish. Whether you’re restoring a single scratch or giving a whole cowl a mild refresh, the results are clean, consistent and professional-looking.
