I have a ton of Lego minifigures that I really put through their paces throughout my childhood (fighting pirates, exploring space... basic stuff really). A number of them are damaged on the torso. Starting at the base on the left and right sides of the torso there are cracks that extend upwards toward the minifigure's "armpit". The cracks cause the legs to be loosely attached to the torso (and hence fall out sometimes).
Is there a way to repair damage (probably not) or hide it and prevent further cracks from creeping up the torso?
