Finally, press the tape down well. I do this by just rolling it into the surface of the serving with my fingers. Then give it a couple of coats of super glue making sure that the tape is completely coated with each layer of super glue.
This makes a tidy, smooth nock point that will be water proof and that will stay put. I always use two nocks, one above and one below, and I use this process for both.
Mine always last as long as the string I put them on.
If I have to remove them, for example if I am changing arrow diameter and need to move my nock a bit. I just carefully cut them off with an X-Acto knife.
