I used that Duragloss on all my windows yesterday, trying to remove all the hard water spots that the dealer let set on it.
Followed the directions perfectly.
It got rid of most of the spots, but not all of them.
So, I did my windshield 3 times.........same result.
Could I be doing something wrong or will it only get most of it off??
Let me know your experience with Duragloss and if you know a better product for getting water spots off the windows.
