[Public-list] rudder post hole fiberglass rot

[John Birch]

Hi Mike,
Would waxed paper and release agent be a thought - just to be sure it 
doesn't bond to the shaft.
The waxed paper around the shaft would be benign and it wouldn't matter if 
you couldn't get it out afterwards.
Just a thought.
Cheers,
John
