I think the wax may shoot off your string, think about it...the string is moving forward very fast and then stops...as physics teaches us objects in motion tend to stay in motion so the string stops and the wax keeps going. It may be a little bit at a time but eventually it would get rid of it. It could be an interesting test to wax your string, put a large piece of paper a few inches in front of your limbs, fire the bow and see what's on the paper? just a thought.
