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

This one-gallon dressing is formulated for hard-to-reach exterior surfaces where traditional applicators struggle. Use it on inner fenders, suspension shrouds, plastic liners, and other textured components to hide fading, even out blotchy areas, and leave a durable satin finish that resists dust and sling. Supplied in a bulk 128 oz size, it’s meant for garages, shops, and enthusiasts who need to decant and cover multiple vehicles or large surfaces efficiently.

How do I apply Bare Bones to wheel wells and undercarriage parts?

Apply only to clean, dry surfaces for best adhesion and even coverage. Spray from a moderate distance for even laydown; for smaller areas wipe with a microfiber, or allow product to set on large textured surfaces where wiping is impractical.

• Shake well before use and decant to a spray bottle for convenience.
• Spray 8–12 inches from surface; wipe smooth sections with a microfiber towel.
• For liners and deep textures, apply extra coverage and let dry without wiping.
• Avoid applying on hot surfaces or in direct sunlight to prevent streaking.
