There is metal under the cover. Not quite sure how much parts are (the glue kit is $$ if i remember correctly). Labor should only be about .7 hr each side. You need to cut the glue with a windshield tool ("rope saw") to remove the defective piece. They are pretty easy to do. It depends on your dealer, but they I would doubt that they would goodwill it since it is just cosmetic, but never hurts to ask.
