coyotefreek, I am going to use the Z-1 to make sure I get rid of all the Liquid Glass Auto Polish on my car. I am planning on doing this: washing my car with Dawn, applying Z-1 and letting it haze, rub OFF the Z-1. Wash car again with Dawn, and then proceed to using Zaino w/ZFX. Can I do this? One wash with Dawn will not fully remove the Liquid Glass. I have the Liquid Glass Pre-Cleaner, but I prefer to use the Zaino Z-1 product to remove the Liquid Glass rather than using Liquid Glass Pre-Cleaner (because washing with Dawn does not remove the Liquid Glass completely).
