I believe pure beeswax is actually slightly better, but I have no
positive quantifiable reason for thinking so, just an "impression".
Seems to "stick" better, but the white candle wax works pretty well
too. I don´t know anybody who has suffered such a break when using it.
The ferrules are also relatively easy to separate after use if one
uses wax on them. May seem contradictory, but works very well in
practice.

Have seen quite a few ferrule breaks though, and the damage is typical
for loose ferrules. Often causes the blank to splinter, "crack", or
delaminate, quite a way down the rod, which makes a "simple" repair
useless. I have tried it a few times, on the strict understanding that
it was at the owner´s risk, but mostly the blank then collapses
somewhere else when under stress. As soon as even a very small area
of the composite is compromised, then the whole section is at risk.
Even very slight practically "invisible" damage will cause blank
failure under load, usually when casting. High modulus fibre blanks
are at considerably greater risk than low modulus fibre blanks.

In point of fact, I don´t know of any way to repair a blank that has
such damage. I have tried "sleeving" a couple, but it looks awful,
adds weight, can affect the action very adversely, also increasing the
risk of further damage, and is unreliable at best.

Modern carbon fibre rods are not easy to repair, and very often not
worth the trouble anyway.
