Burb, i had the ever present crease wher the check strap failed and creased the door. i thought it would be easier to clean out ant bits of rust and such in the bottom of the door as well. the job is pretty straight forward just take your time , and dont try to take the skin off from around the window opening. use a cut off disc to separate the skin from window frame at bottom of said opening right where skin meets window opening . if done right should be 2 small cuts easy to repair.
