well i did it good this time! i warped the heck outta my door while welding in a donor plug to fill the recess around the door handle.(cloning an earlier model) the low spot is "oil canned" it will pop out with pressure from behind, but will pop back when pressure is released. if i understand my research correctly, the steel around the weld has shrunk causing the warping & needs to be streched out to releive the stress. what is the best way to do this???? secondly, how do i prevent this from happining again on the other side, i did the skip around tack weld method, like i always have but this still happened.
