Mothers cleaner wax in the red round tin is awesome. 3M is comparable to mothers, but I prefer using a round cotton terry cloth applicator with the paste. The "cleaner" waxes remove bugs, tar and road grime with ease. Mothers spray wax is excellent after every wash. The mothers clay bar system will make your car shine more than when it was new, but really isn't necessary for newer cars. Meguiars is okay, but I get too much white powder with it. When I use mothers, it is the only wax that will allow the towel to slide right off the hood.........This may not be scientific, but the paint is smooth as glass. Bottom line, whatever wax you use, use it at least 4 times a year on your car.
