We used our Expedition to pull a float in the 4th of July parade yesterday and while setting up one of the trailer walls got leaned up against the passenger side. Needless to say, the 2 bolts sticking out etched two nice spots down to the metal. Besides getting touch up paint from Ford, does anyone have any other recommendations? It looks like I may need a little primer to apply to the metal first? The color is the white tri-coat.
