[C38] Binding Halyards/Masthead

[Joseph Launie]

Russ,
    While WD40 is good, Kroll (sp?) penetrating oil is better. It will 
free up just about anything. I would go up the mast, give it a good shot 
of your penetrating oil, come back down the mast and have a beer while 
the stuff penetrates and then go back up again. Do not rush too much 
over the beer but a second one is probably contra-indicated for mast top 
work.  Joe Launie Macavity, Commodore
