Meguiar's

Make your wax protection last longer by removing bonded surface contaminants and restoring a smooth-as-glass finish with Meguiar’s Smooth Surface Clay Kit. After you wash and dry your car, rub your fingertips across the top surfaces. Don’t be surprised if what you feel is rough and bumpy. If the paint does feel rough, what you feel is the presence of harmful environmental contaminants such as over-spray, fallout, brake dust, tree sap and more that have bonded to your paint finish. No amount of car waxing will remove these contaminants. Applying car wax on top of bonded contaminants takes more effort and bonded contaminants prevent a freshly waxed surface from reflecting light and shining to its full potential. Bonded contaminants also inhibit the adhesion of car wax.
