While you're washing your wheels, spray Adams All Purpose Cleaner in your fender wells and give them a good scrubbing with a fender brush. Let the cleaner dwell while you clean the tire and wheel, then give everything a thorough rinsing. If your wheel wells are really nasty looking, scrub them twice. After washing, allow to air dry, blow dry or towel dry.
Once dry, spray a light coating of Adam's Undercarriage Spray to all areas of the fender well, then work the product in with an old towel. When you're finished, your black fender well liners will have a perfect satin black finish. They literally become invisible and no longer stand out where they can rob your car of its detailed beauty. Now you're ready to detail the rest of your car.
Adam’s Undercarriage Spray is a silicone-based, sprayable fender dressing that is designed to lay evenly and dry to the touch in minutes. Now with added silica-resins, this same great formulation has increased longevity and durability to keep your ride looking detailed for longer! This formula allows users to achieve a rich, wet, lustrous shine on their fender liners, undercarriage components, and underbody areas. Just a few sprays of this product evenly covers your vehicle’s out-of-sight areas and protects them from road grime being built up.
PRO TIP! Adam's Undercarriage Spray can stain concrete if it is allowed to drip off. Place newspaper, cardboard, or scrap towels under the fender prior to spraying.
