Great product. Used it for 5 years now. Limit the streaking by two ways: Using a spray bottle, lightly mist a paper towel then buff the glass after product dries. After streaks are detected just use a dry cotton cloth (towel) and buff the streaks out. Not that difficult to have streak free glass. But the streaks will be annoying during night time traveling.
