I have a Fiat 500 Pop 2012. I have a dent that is approximately 12 to 14 inch wide and 14 inch in top to bottom that is located in the side panel right behind the passenger door. I need somebody to tell me how to get the inside backseat panel off without damaging anything. Any and all advice is appreciated. And if anyone has any Surefire tips on removing dents, I'm all ears. Thanks a bunch!
