    Magic Touch

    This is a product that sets your detail apart from the rest. It will make the job more complete and is one of the final touches on most vehicles that leave our shop. We also use this on full under carriage details for a perfect finish!✨


    so important for a truly clean looking car

    smells like grape Kool-Aid and looks so clean. Garage smells amazing after using this. Make sure to use this before you wash because if any gets on the paint it will attract dust and look dull. Definitely buy the gallon. I go through this faster than most products.

    Often overlooked area, but what a difference!

    Great product. Most people never think about dressing their wheel wells, but do it once and you'll do it every time you wash your car. Follow the instructions because this product will stain the ground.


    Works Great!!

    This product works great leaves wheel wells looking showroom condition You won’t regret buying it, just make sure to buy the gallon.

    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.
