Okay big REVEAL, with much appreciation to @sfischer over on twitter. Red paint scrape more than likely came from braces that the tow truck company EZ Tow uses when they "right" an overturned vehicle. The attached photo shows EZ tow equipment being used by the Goodyear Fire Department on a mock Training exercise! When S Fischer showed this to McGrath he was not happy. As indicated in the photo, the top lips closely fit the markings on the fender, and that was the fender that was DOWN and would therefore get the bracing as the were pulling it back over in its wheels.
