I am not sure what is the best route to take for caring for my rod's ferrule. Two piece graphite rod with the top over bottom section ferrule. I have heard that wax is good, bad and indifferent. What should I use? Nothing? Anything? How long do these ferrules usually last before they will no longer hold together? This is a fairly expensive blank if that makes any difference. Thanks.

I heard that Parrafin/Wax is no the best idea for use on the Ferrules. Not 100% sure here, but I think it picks up dirt/dust/stuff that will adhere to the male section and possible damage the female section.
I just put some U40 Ferrule Lube on a 2-piece Bass rod I built. Now I haven't fished it, but I have been toying with it to see if it works as advertised. So far: no build up of whatever the material/Lube is; keeps the two sections together nice and firmly; taking apart the rod and rejioning it is nor problem. I applied it as per the instructuions.

I'm sure Ralph will chime in here, as he was the one to tell me Parrafin = no good in the first place.

Good luck, Billy

After much experimenting, I have found that for my work I don't use or recommend any lube.

Billy is correct. Do not ever use paraffin on your ferrules, even though there are still rod manufacturers out there that still insist on recommending to use it. It is a continuous bewilderment to me why so much ignorance exists in the industry. Graphite and/or fiberglass ferrules are fit with a very close tolerance, parafin simply cannot be absorbed within that tolerance. I have seen perfectly good, practically new ferrules split because of the application of paraffin. parafin then collects dirt and grime which acts as an abrasive. Graphite to graphite or fiberglass to fiberglass is quite abrasive in itself and untreated ferrules wear down severly quite prematurely. Oils and greases are no good, you need something dry. That is the reason for the development of Ferrule Lube. Ferrule Lube is designed to do all the good things that a ferrule needs without any of the bad things that they don't need. It is dry (after a few seconds to evaporate the carrier), and has no film buildup. Its lubricating qualities are imbedded within the surface of the male and female ferrule. While in place it actually assists in the ferrule to be tighter than is is without it. There is never any sticking, and wear is reduced about 99%. No rod ever leaves my shop with an application of Ferrule Lube.

Will give it a try Ralph.
