Chemical Guys Dark Shine Spray for Wheel Wells & Trim — 1 Gallon, Satin Non-Greasy Finish

Chemical Guys Bare Bones Dark Shine Spray is a fast-spraying, non-greasy dressing that restores deep, satin-black color to wheel wells, undercarriage plastic, rubber, and exterior trim.

This one-gallon professional-size formula was created to revive faded and textured underbody and trim surfaces that standard dressings struggle to reach. It lays down an even, dry-to-the-touch satin finish that reduces dust pickup and sling while blending blotchy plastic for a uniform appearance. The concentrate-ready gallon is sized for shops, mobile detailers, and enthusiasts who want consistent results across multiple vehicles or large surface areas.

How do I apply Bare Bones to wheel wells and fender liners?

Application is simple: work only on clean, dry surfaces for best adhesion and appearance. You can spray directly from the gallon into a secondary sprayer for targeted work, then either wipe with a microfiber for an even coat or let it set on larger textured areas for fuller coverage.

• Spray evenly 8–12 inches from surface; avoid oversaturation.
• Wipe with a clean microfiber for a consistent satin look on trim.
• Leave on textured liners or inner fenders to self-level for extra depth.
• Decant to a trigger bottle for tight areas and suspension shrouds.

Will this dressing feel greasy or attract dirt?

Bare Bones is formulated to dry to a satin, non-greasy finish that resists sling and minimizes surface tack. Because it doesn’t leave a heavy oily film, treated areas stay cleaner between washes and are less likely to collect road dust compared with traditional wet-look dressings.

• Dries to a dry-to-the-touch satin—no sticky residue.
• Reduced sling keeps wheel wells and trim tidy after driving.
• Helps hide faded spots without a shiny, oily look.
• Suitable for routine maintenance without frequent reapplication.

What materials and parts is this safe to use on?

This spray is designed for exterior plastics, rubber, and vinyl commonly found in undercarriage and trim applications. It’s safe for inner fenders, bumper shrouds, wheel well liners, suspension covers, and exterior trim panels—not intended for painted surfaces or inside the cabin.

• Safe on plastic, vinyl, and rubber exterior components.
• Ideal for wheel wells, undercarriage trims, and textured liners.
• Not recommended for interior fabrics or untreated painted surfaces.
• Works well on RV undercarriages and off-road vehicle components.

How will a gallon improve my detailing workflow?

A 128 oz supply is ideal for garages, shops, or enthusiasts who service multiple vehicles. The gallon format reduces the need for frequent repurchases and lets professionals refill smaller spray bottles for fast, efficient application between jobs.

• Bulk sizing lowers per-use cost for shops and fleets.
• Easy to decant into trigger bottles for targeted spraying.
• Consistent formulation ensures the same finish across vehicles.
• Great for seasonal maintenance or resale prep to boost curb appeal.
