If I were fixing this kind of problem, I would sand the good area around the offending area, very good, so there was a slight indention in the good area. Then I would cut out the offending area with a saw. I would then glue in a good piece of foam with hot glue. I never use the mixable foam as I understand that it does not quit expanding for a very long time and when the heat hits it, it starts expanding all over again.
Now, just sand to shape and cover as you would normally, overlapping the good area you sanded down. A little super fil, primer, and paint and you will never know that it had been "boogered up".
