[Sonar] Re: Keel fairing

[markkoch]

Thanks Tom (also Chris and Marty)

I guess I will seek some information on what to use for primer on the 
bare lead.  Chris mentioned Interlux 2000 and Marty says there is a 
brochure from West.

I have to decide if I am willing to uncover all the lead or just do the 
one section.  I believe someone faired the keel and I would hate to lose 
the current shape.  I don't know how well I could recreate the shape if 
I were to remove all the sound (so far) filler.

If I do the bad section and then seal the entire keel with West epoxy 
maybe there would be no further blistering for a few seasons.

This was a Geneva boat so it is not used to being wet sailed I guess.
