I wonder how many tiers use wax on their tying thread? I do. It is the "traditional" way I was taught some 45 years ago. Most times I also use a waxed thread. There always was the argument that head varnish doesn't penetrate waxed thread but I have taken heads apart and found quite the opposite given that the varnish is thinned enough. I also use a tacky wax for dubbing although it is not always necessary with some of the commercial dubbing available today. I have gone back to making my own waxes again given that Overton's is no longer available and my supply is gone. Look forward to your comments and thoughts on this sometimes sticky subject.
