A lot of times these damages occur during transportation, not actually during manufacturing. I see it a lot in my line of work, and being that a lot of cars pass in and out of those places they tend to over look minor details and just wait for them to be brought back to them. I would be willing to bet they would cover it under warranty as long as you dont say you did it, because in all honesty the dealers like the warranty money they get from Ford. i know my company does lol.
