No not yet, I just got my mass of Z supplies in today, so I wish I had ordered the Z glass polish also. But the problem is that I have tinted windows so I could only apply it on the outside.
And another problem is that I really really love Rain-X, and I don't think I could use Rain-X and still use the Z glass polish.
