Z-12 Works Great!
 

I've used most of the Zaino products with great results but for some reason I avoided using Z-12 Clear-View Glass Polish. Instead I just used regular glass cleaner and wipes from the Pepboys thinking it would be just as good. Lately I've been having trouble getting the streaks off my glass, so I finally broke down and bought some Z-12 and used it this morning. The stuff smells and looks like colgate toothpaste but it was easy to use and my car windows look amazing. Thanks Zaino!

I sound like a commercial.

hmm, I've used almost every product Zaino makes....except Z12. I just usually use Invisible Glass.
