All the front end pieces were painted off the car, fenders, buckets, headlight doors, valence, deflector, grill panel bar and hood. No hardware used on any of those items was painted. The only painted hardware on the entire car is for the trunk lid hinge, door hinges and two screws for the rear valence to leave it hanging for painting.
