So I have a 2000 f150 ext cab, the previous owners hit a pole & dented the passenger door just behind the fender. Now the top of the door won't seal properly and with winter on my heels I'd like to somehow straighten the top so it seals again. I remember a 2x4 trick from high school autobody but think it's only for alignment. Correct me if I'm wrong or a tip to try to bend the top of the door back until I can afford to fix it properly. Thanks

 

This coils and probably will mess your paint up but you could use a blowtorch to hear it up then use a large pair of pliers to bend it back when it is hot

 

We rolled a truck one time, and to get the top of the door back so we could close it, we took a 2x4 and with the window down, put the 2x4 from the top outside, and the door inside, and bent it back slowly that way. Surprisingly it worked rather well. You end up using the inside of the door for the leverage, and the 2x4 bending the top back. You might try that, and it is cheap.
