After what happened to Jay's rod on the recent trip to Bugatti, I thought this thread might be useful as I have noted that most people don't wax the joint of their rods. It is always a good idea to wax the joint of your rods. The wax reduces slippage very significantly and helps to keep the two pieces together with minimal movement. It is not uncommon for a rod to slowly separate as you use it through a day. If is slips out excessively and you hook a fish, a breakage is a very likely result.
A wax stick is a very minor investment and it works very effectively. All you have to do is apply a very thin layer to the rod section of the joint. It also is quite effective in holding the two sections together if the joint has become loose after long term use. I've also found that it helps in preventing the two sections from becoming stuck together.
I've attached a photo of the two I use, Tiemco and Smith. if you can't find it, then even candle wax, although not ideal, is better than nothing.
