I picked up the Stoner Invisible Glass today as many of you feel it is a great glass cleaner - good enough reason to give it a shot. The application instructions state to spray the glass directly (don't like this idea). Does anyone spray their towel instead of directly on the glass? I really hate overspray, but was wondering about the effectiveness of the cleaner if sprayed on the towel instead. Any comments? (The glass on this car only sees periodic dust and an occasional insect splatter - rarely dirty).
