Another way to tap out the dents around the rivets (from the inside) is to use a length of half inch wooden dowel that has a hole drilled in the end, say 5/32", so that you are tapping on the dented flange/skin just around the rivet, rather than on the rivet shop head. This helps to avoid potentially damaging or loosening the rivet. A few gentle taps on the dowel with a small hammer should improve the finish.
Note this method is only relevant if the cause of the dents is over driven, or inadequately bucked, rivets. If however there was a gap between the flange and the skin before riveting then it won't help...
