I just bought a 2020 super crew. It was being driven by one of the owners of the dealer and had 2800 miles on it. I took it in for opti coat and ppf three days after I got and the installer pointed out run marks on all four fender flares. I know there are previous discussions on this. I took it back and Ford denied the repair. The dealer is willing to give me 50% off to repaint them ($450ish}. My question assuming proper washing are they still prone to streaking?
