Ok so, I got an 08 black f-150, something got on the hood and windshield. It looks like primer overspray and I could be wrong. But it comes with a fingernail easily, and not so easy when being washed. I know its making the wipers streak as well Can anybody point me in the right direction on how to remove the material from the finish and glass?? I appreciate it thanks
