It kind of depends on what part of the cable. For most of it, red tape is fine. The part that always gives me problems is where it goes from volume to power and is on top of the frame. I use yellow tape for that part. If the volume buttons are giving you trouble, cut out tiny little pieces of red tape.
I'm pretty sure all of those volume flexes were made when Reagan was in office. The adhesive is always messed up on them when I go to use them.
