I remember somebody mentioning that over time the -9 rudder skins were showing signs of cracking at the stiffeners, and that some recommended prosealing them to absorb the vibration. The most recent instructions from Van's don't seem to indicate the need to do this.
Is this an issue?
Is this what other builders are doing (prosealing them)?
If so, does the proseal just need to go on the trailing edge of the stiffeners (where it comes to a pretty sharp point) or are others prosealing the entire stiffener?
Thanks,
Steve
