Hi, Does anyone tried Optimum Poli-Seal on Glass? Is it good? I have this product and want to make a light polish, water spot removal and seal my windshield and want to know if this AIO is good for that. According to the forum Klasse AIO is an excellent choice for that, but since I have The Optimum AIO I was wondering if it will work as the Klasse or not, What do you think? Can I apply it by hand with a MF applicator and get good water spot removal and good protection? Thanks in advance!
