I have a 2001 mustang convertible and my wife just got finished washing it with a sprayer. All of a sudden sections of paint start flaking off on the front bumper. This is the factory bumper and it has never had a bra on it to cause rubbing etc and has never been wrecked. Any ideas on this? BTW I bought it from a dealership about 3 months ago and bought their extended warranty. Should this be covered under factory warranty or under the extended warranty. Or am I just out of luck?
