I would have to have a shelf full of Zymol!
Here are the results:
Guide to the Ratings
We tested using sample panels uniformly finished with white or black automotive paint, both with and without clear coat. Some were left to weather for 12 months on our testing facility’s roof and others were put into a device that simulates extreme weather conditions. The panels were brought into a lab weekly, where technicians washed and dried them, and applied drops of water to measure beading effect. How well a wax beads, or repels water, is one way to determine whether wax still provides protection from acid rain and contaminants. To test for ease of use and how well products worked to clean and improve gloss on fading paint, we used real vehicles, some of which had rarely or never been waxed. The
overall score is based primarily on gloss; durability; ease of use; cleaning; resistance to scratching, swirls, and hazing; and plastic compatibility. We applied a quarter-teaspoon of wax and used an equal number of buffing strokes with each sample on each panel. To assess
gloss, we did side-by-side visual comparisons. Gloss-measuring devices exist, but their measurements don’t necessarily translate into what the human eye sees. For our
durability tests, we tracked how water beaded to show how quickly the wax wore away. Our
cleaning and
scratching/hazing tests also relied on side-by-side visual comparisons of test panels. For the
ease-of-use tests, we used cars owned by staffers.
