Does it matter what bow string wax you use? Scorpion wax, Tex-tite?

Just get some old Tex-tite.  It does not matter if it is Dacron or a newer string material.  Bowstring wax is mainly for sealing the string from drying out, which is the main reasons most strings get weak or break.  It also helps keep the string waterproof.  There are many newer waxes with silicone or some other lubricant, but I have never found them to be as effective as Tex-tite and most don't seem to coat the string as well or last as long between applications.

I use a big stick of beeswax from the a grocery or craft store. Not the parrifin!

I mix about 1 tsp. of honey with about 1/4 lb. of beeswax.  Makes it extra sticky and the smell ain't half bad either.

I think it was Rube Powell that told me about 1954 to keep your string waxed about every 2 months if shooting regularly, because it lubricates the individual strings, stopping ware and tear as they slide against each other with every shot. It sounded good, and he was a national champ, so as a kid I absorbed everything he said. I found burnishing the string with a piece of leather heated the wax and let it get deep within the bundle.

Leather to burnish the string.....hmmm.  No wonder I've been burning my fingers all these years.    :D

I use the string makers beeswax from Kustom King. Tacky and durable. I also use a piece of leather like Biff after burning my fingers like Scriv

Biff, I agree, keep a small patch of leftover elkhide in my bag and always know where it's at. When waxing I just pull it out and start spit shining that beeswax into the string. Smooth and shiny.
And did you all know that honey is the only pure food known that will not spoil. Use Beeswax!!!!!
