I was skeptical because of some reviews. I applied on windshield quickly, horizontally and vertically, then I wiped with clean micro fiber. IT WORKS ! I emptied a bottle of water on the windshield and we can see the water being repelled. I compared with side windows with no aquapel and the difference is clearly noticable. So I’ll buy again !
Product was dry when I opened the bag, didn't do anything on the windshield
