One Piece has a great story and does not have a lot of filler episodes.
This vastly reduces the need for sanding to shape and wastage of filler - the filler removed by the rule can be used elsewhere on the vehicle. The technique works very well for short lengths of filler. For areas longer than 200mm the drag of the filler on the rule makes the rule bend around the filler.
