Anybody know if its illegal or legal in California to apply clear winshield protectant, like the kind used for clear bras, onto your front windshield. My FiST windshield is becoming covered with little pits and cracks after only one year. Unlike most windshield products, I'd like this film applied to the outside of the window. I have replacement/repair insurance, so I'm hoping to get hit by a rock big enough to crack the windshield. Then, if its legal, apply clear protectant to the windshield.
