I am getting ready to place my first order of Zaino (Z-2, Z-5, Z-6, Z-7, Z-14, Z-18, ZFX). Can Z-12 be used on the glass in our cars? Is the glas "coated'? Obviously, I would not use it on the tints, but I would like to use it on the outside glass, and on the inside windshield.

If not, what kind of glass cleaner do you all recommend?

 

The Z-12 is an abrasive and is used to remove water spotting and wiper marks. Works fine by hand, but need a lot of elbow grease. Work it in in small sections. I now use a random orbital, which does a great job in one-tenth the time. Then, you need to use your favorite glass cleaner (please, no ammonia) to remove any residue. I like Stoner's Invisible Glass or Sprayway.
