"Waxing" of strings

Was extremely surprised when I received a request (from a chap age about 40) for a waxing treatment on the strings after I had restrung his racquet!

Why?

The practice used to be common long ago when strings were made from natural gut. In those days the racquets were made from wood. A layer of wax was normally applied to the strings before and after usage, to protect the strings from wear&tear (via friction) as well as from water.

I obliged and applied a layer of wax on (both sides) the strings after restringing with Yonex BG66 Ultimax @ 26lbs.

Pix of the result as per attached below.
