cut a slit in it?!? i would push it back out till it stays, then work it with a body hammer and dolly.
use minimal bondo to clean up the ruff spots.

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. 
While welding in an upper rear qtr patch panel I experienced the oil can warp. I was using a copper bar but obviously I welded just a touch to long. I tried a veritical cut to relief the metal but ended up cutting the horizontal weld, pushed it back into alignment, re-welded and I beleive it turned out just fine.  I did not have a shrinking hammer. In your case I like the idea of heating and shrinking with a wet rag. Good Luck!

what happened was when you welded it expanded the metal causing a high spot and the panel formed a oil can.
now to fix it properly with a heat shrink.
you need to hit the oil can area UP and then find the highest point in the panel. a lot of times it will not be in the oil can area.
heat this spot up with a torch until it's cherry red, note don't heat up a area any bigger that the size of hammer head, i my myself stick with about 1/2".
now hold a flat dolly behind the heated area. strike the panel around the flat spot with the force of the blows towards the red spot. hit it about 6 times around the circumference of the spot. then strike the heated spot directly forcing the metal you moved towards the heated spot to to shrink.
now cool the heated spot and the oil can should be gone.
you just did a heat shrink.
if not find the next highest spot and repeat the above steps.
the most important thing to remember is heat shrink the high spot of the metal. a lot of times it won't even be in the oil can area it will be next to it.
i myself don't like shrinking hammers and things like that. if used improperly they can make more problems than what you had.
perception is 90% of reality

With hindsight I believe MrT2U's method would have been the best solution for my oil can situation. Since I ended up making the horizontal and then re-cutting the vertical seam I am very thankful I had the butt weld type panel clamps...
