Recently I have seen some companies starting to place a warning on quick release skewer instructions that these particular skewers are not to be used with carbon forks that have exposed carbon drop outs.

I assume this means carbon forks that have no sort of metal protection on their carbon drop outs to protect the carbon from the clamping nut/skewer.

Has anyone experienced any problems with exposed carbon forks and skewers ? I have never seen a skewer specifically manufactured to 'remedy' this issue, if it is an issue at all and not companies covering their butts.
