I've just had three dents taken out of my father's black metallic Porsche 996 with excellent results. Two of the dents were slightly less severe than BAd124's dent. The other was a bad 9 inch tall vertical crease in the door where someone had obviously deliberately opened their door onto the Porsche. I was very satisfied with the results, although the door crease remains very slightly visible (but not to anyone else). I would recommend this: it is a lot cheaper than new panels and paint.
