Do you have a branch that you bent a bit too far, damaging the cambium layer and bark, or do you have a branch that you are going to make a radical bend or twist in? Wrap it with Parafilm. This clear film sticks to itself and provides support to lessen the damage caused by radical bends or twist to branches, giving the branch time to heal. I have seen it used by Kathy Shaner and she highly recommends it. Parafilm is flexible, moldable, self-sealing, moisture-resistant, semitransparent, and practically colorless. Directions for use are included.
