Never heard of this
Did a search here on string wax and to my amazement read a couple of posts that stated to wax everything....including the part of the string that goes around the cams. First time I have ever heard this or read this, and I don't do it. The only part of the string I wax is the string itself, just my opinion but I don't recommend putting wax on any part of the string/serving that wraps around the cams/wheels? Opinions?
