I ask this because I wax mine whenever it occurs to me, which isn't very often. I replace my bowstring about every year, and I know the flemmish strings are waxed pretty thoroughly as they are made, so sometimes I wonder if I even need to bother. I can't tell any difference whether I wax it or not. What is the purpose of waxing the string, and am I missing something by not waxing it more often? Do you also wax the serving when you wax your string? Do you try to wax the ends of the string and the parts covered by string silencers, or just the parts that are easy to reach?
