Expert Notes

Chemical Guys Barebones, also written Bare Bones, is a 16 oz oil-based dressing for the parts most people never detail: wheel wells, arch liners, subframes, springs, suspension components and bumper covers. It sprays on, dries to the touch within minutes and leaves a rich dark finish, and Chemical Guys says its weather resistant coating helps resist road salt, rust, corrosion and discolouration. The maker lists plastic, rubber, stainless steel, metal and aluminium as suitable finishes. We treat it as the last stage of an underbody clean: degrease, rinse, let everything dry, then spray and buff off the excess after around ten minutes. It suits show builds, lifted vehicles and daily drivers facing salted roads. Pair it with a degreaser, long wheel arch brushes and dedicated microfibre towels.

Perfect For / Suitable Surfaces

  • Wheel wells
  • Wheel arch liners
  • Subframes
  • Springs
  • Suspension components
  • Bumper covers
  • Plastic and rubber underbody trim
  • Metal and aluminium underbody parts

Caution: Keep the dressing off brake discs, pads, callipers and tyre treads. The safety data sheet classes it as a combustible liquid, so keep it away from heat, sparks and flames.

How To Use

Application

  1. If you need to get underneath, raise the vehicle on ramps or axle stands on level ground, never on a jack alone.
  2. Degrease the undercarriage, wheel arches and suspension to remove mud and road grime, then rinse thoroughly.
  3. Let every part dry fully before applying the dressing.
  4. Spray Barebones onto the arch liners, subframes, springs and suspension parts, then give it a few minutes to dry.
  5. After around ten minutes, buff away any excess with a microfibre towel.
  6. For a deeper dark look, apply a second coat and buff the excess again.
  7. On heavily faded plastic and rubber, work the dressing in with a microfibre towel and repeat as needed.

Aftercare

  1. Check brake discs, pads and callipers for overspray and clean off any you find before driving.
  2. Wipe any overspray from paintwork, wheel faces and tyre treads with a clean towel.
  3. Wash the undercarriage regularly in winter and redress it once it is clean and dry.
  4. Wash towels used with dressings separately from your paintwork towels.
  5. Store the bottle closed, between 5°C and 30°C, away from heat and out of reach of children.

Top Tip: Dress the arches only once the car is fully dry, then buff off the excess after about ten minutes.

Frequently Asked Questions

What size is the Barebones Undercarriage Spray?

Chemical Guys Barebones Undercarriage Spray is the 16 oz size, and it comes with a sprayer head.

Where can I use it?

Chemical Guys designs Barebones for undercarriages, wheel wells, subframes, springs, suspension components, fender liners and bumper covers. The maker lists plastic, rubber, stainless steel, metal and aluminium as suitable finishes.

What finish does it leave?

Barebones leaves a rich, dark finish that dries to the touch within minutes. Buffing off the excess gives a drier look, and a second coat gives a deeper black look.

Does it protect against road salt and rust?

Yes, Chemical Guys says its weather resistant coating protects against road salt and helps resist rust, corrosion and discolouration. It will not repair corrosion that is already there, so treat any rust before dressing.

Do I need to clean the undercarriage first?

Yes, remove mud and road grime with a degreaser, rinse, and let every part dry before spraying. Chemical Guys UK recommends this order in its Bare Bones guide.

How long does it take to dry?

Barebones finishes dry to the touch within minutes. Chemical Guys UK suggests buffing off any excess after around ten minutes.

Can I spray it near the brakes?

No, keep it off brake discs, pads and callipers, as with any dressing. Spray carefully inside the wheel arches and wipe off any overspray before driving.

How should I store it?

Store it closed between 5°C and 30°C, away from heat, sparks and flames, because the Chemical Guys safety data sheet classes it as a combustible liquid. Keep it out of reach of children.

HQ Suggests Tips & Insights

  1. Use a long-reach wheel arch brush to scrub deep into the liners.
  2. Mist the dressing onto a microfibre towel for edges close to paintwork.
  3. Cover the brake disc with card while spraying inside each arch.
  4. Dress the arches on a dry day so they are not splashed straight away.
  5. Give show builds a second coat for a deeper black look.
  6. Check the springs and subframe for existing rust while you work underneath.
  7. Wear gloves and eye protection, as the maker safety data sheet advises.
  8. Available with UK-wide delivery from The Drivers HQ.
