It's really frustrating to buy a car in the daylight not knowing when you drive at night in the rain there is a terrible glare across your front windshield from oncoming traffic or the tail lights of the cars in front of you. I've tried Rain-X, newspaper oil, windex, anything I can think of to get it to stay clean and water bead off instead of smearing. Nothing worked. My last resort is to trade this horrible Blind-spot of a car off to make it someone else's problem.
