Today I came home from work, and I look at my opel and see a little paint chipping from my drivers side door so I think, "Oh I never noticed that before." Well I go to get in it and the door was not wanting to open. Then I look harder, and there is a dent in my front panel like the door got opened up too far. Well my dad tried to back it up and got the door stuck on a tree!!!!! How can I quickly fix this dent, and the door. HELP!!!!!!!!!
