Wolfgang Deep Gloss Liquid Seal description says it's great on glass, but is it referring only to non-windshield glass or can it be used on the windshield without causing chatter or streaking? In the past, I've tried some different things which has some residue where you can clearly see something where the passenger wiper stops and reverses direction at the center of the windshield. Would the DGLS not have this characteristic? I'm just trying to find something that will prevent my wipers from chattering on my 1 year old car as well as my older 10 year old car. Thanks!
