    Better Than New!

    Simply put, this product WORKS! I keep hoping Adam's will have a "upload photo" feature to these reviews, a picture says it all...we just detailed a 2012 lifted Ram 3500 with original inner fenders and extreme undercarriage oxidation. Bottom line...when the customer picked up his truck, the first words out of his mouth was, "HOLY ****!!! my truck looks better than when I drove it off the dealer's lot!" As with anything like this product...proper prep is the key to success. If you're still reading this...STOP! Add it to your trunk, you'll love it!

    WOW!!!

    This is one AMAZING product!!! My Ram fender well we’re filthy with dirt & concrete spray up from roads. I would wash and scrub and still would not come clean so decided to try this product. WOW!!! AMAZING!!! After I had washed my truck I tried this by spraying on fender wells and wiping off. That simple!!! No scrubbing!! Spray & wipe and the fender wells to brand new!! I would highly recommend this Adams Polishing product!!!

    Do you like Grape Juice

    There is one huge negative I found. At night, my Ring door bell goes off because the wondering cat walks by and does a full smell down my SUV. My phone is going off, MOTION in the the Driveway.. Ohh wait, its a cat smelling my car again. But, overall, this stuff works great. It doesn't build up. It looks great. I would only get it, if your vehicle has wheel wells that are exposed like a big truck or suv.

    Summary

    Great product for wheel wells that haven't been taken care of in a long time. I spray it on a old microfiber then wipe down the wheel wells to help keep the mess down as this stuff does stain concrete driveways. My garage was okay since I have it sealed. I highly recommend this product.

    Summary

    Finally I can say goodbye to my **** faded black wheel wells. This product is perfect for topping off your detail and gives the car such a nice complete look. The only con to this product is the fact that I want to order the gallon now.


    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.
