In the last period I've seen many "C" clips (such as this one) from my sets that lost their clutch power.
So I've car doors that falls in a creator set, wing opened thanks to gravity in my micro x-wing, and so on...
I'm trying to find an effective way to restore or at least improve the clutch power.
For minifigure hands is almost easy, that because I can use a round 1x1 place, place it over the hand and leave it for days/weeks/months... At the end of the period the slight deformation is enough to restore a bit of clutch power.
Different kettle of fish for the "C" clips, where round plate don't fit. Any idea different from using a bench vise?
