while you guys may have never heard of it, and don't believe it works, bcy advises it, specially with 452x because its so thin. it will do no good unless you're using a wax - and i suggest bcy-ml6, that has silicon in it. according to the folks who make the material and the wax the silicon will seep thru the serving and into the string underneath to keep the fibers conditioned. its not something you would need to do more than once every couple months, and you don't need to lay it on thick.
i do it on my own bows every once in a while. as the serving is also made of the same materials the string is madeof (weird huh), it will also keep the serving material conditioned and make it last longer.

also,when applying a quality silicon wax to todays materials -its not like the old days. just put it on gently with your fingers. you can wipe it off with leather or a paper towel, but don't rub it in with either, and don't getthe string hot. you don't even have to get it warm. the silicon will seep in. if you heat the string with friction you are actually meltingthe wax, and the wax that was in the center of the string is moving towards the surface. yes, its different than the olddays, and disagree all you want, i don't care - you're wrong.
