Invisible UC is Visible

Invisible Under Carriage spray is a must have for a finished look. I use this every month to keep the under carriage looking clean. Once you start using this spray the wheel well liners are easy to keep clean and looking like new. DO NOT use this on a hard surface driveway because it will stain it. Make this part of your detail arsenal………. Try it and you will like it!

Great product

It's the best I've tried. That's why I bought a 1 gallon bottle

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.

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.
