Clean out the old foam and try to wipe with scotchbrite between the bar and door skin. Get a 2 part epoxy foam from a body & paint store called anti flutter foam. It will mix in the tube as you squeeze the gun and it will expand & fill the gap without pushing the door skin out. The foam in the rattle cans will push the sheet metal out and you won't be happy. Put a silver dollar size spot about every few inches and that will support the skin just fine.
