the primary problem that crops up w/ the barn doors is rusting at the bottom from condensation in that inaccessabile area, and it's NO fun to open the crimp around any door and get it back together properly, so "just" pulling the skin off shouldn't be on the list of possibilities
to straighten body parts you first need to directly reverse the force that caused the damage - assess that well - pics of the damage might get some more help, and then if the mod decides it should be moved, it'll be moved
