Excellent product for removing difficult waterspots.
March 24, 2015
Had some HORRIFIC waterspotting on the glass of a newly acquired BMW from Oregon. (I have worked around cars most of my adult life, and had never seen anything like it.) Tried the usual methods, including vinegar, Flitz, and mild abrasives via machine with no luck. 2 passes with the 1Z product and a yellow pad knocked out nearly all of it. This product will make the glass appear stunning, in addition to leaving a protective coating that sheets water in a ridiculous manner.
A few notes - It's tempting to work the product too long, which only produces excessive dust and doesn't seem to have any extra cleaning effect. Otherwise dusting is somewhat minimal, a small price I was happy to pay to see the waterspots gone. Also, using an excessive amount of product is unnecessary. While the can is small, it goes a long way if dispensed properly.
