gibblet,

Sorry, I read it fast and didn't even notice "cable".

I've used Brownell's Liquid Lok on most of the strings I've built. I don't take the wax off, even though their instructions say to. At the beginning, I did experiment with taking the wax off and then heavily re-waxing after the string sat for a day. I never had a problem with any of those strings. However, I decided to experiment without rubbing the wax off, and it seems just as effective. I'm not sure I would call it a glue, but even if it is, it's not harmful in any way.

Unfortunately, there is no way to know it's exact affect, because you never know what might have happened if you didn't use it on a particular serving. While using it, I have been able to make some surprisingly short servings without any movement. Maybe the Liquid Lok had nothing to do with it, but it also didn't degrade the string in any manner.
