I have used Xino and love it. I have put it on the windshield plastic lens covers and whatever you can think of and didn't damage them.
Once you apply it on the windshield it turns it into a crystal like material real shiny and nice and it actually give a real good shine to the rear lights and the front light (the plastic covers).
I can verify that it doesn't damage the car. Just don't use it inside for leather
