Gee, I wonder what sailors did for the 1000 years prior to West Systems coming along? LOL!
Were it me, I'd simply go with the tar and paint
method, like the sailors of old (ablative paint, of course, and several coats of it).
In fact, it is kind of me, because I'm in the process of redoing my rudder right now while the boat is hauled out for maintenance
. I've got the exact opposite problem...a rudder that somewhere in the past 30 years has been coated in a thick coat of fiberglass
, which now is apparently leaking and beginning to seperate in places, with the wood inside of an unknown condition. What I'm going to do is use the old rudder as a pattern to cut a new rudder out of 2x12, then simply paint the new rudder with multiple coats of ablative paint.
I'm still debating what to do with the original rudder, and I believe I'll just use it to test my epoxy patching skills, paint it, and save it as a pattern/backup, since it's a good bet that the wood core
is at best in poor shape in spots. At least with a painted wood rudder I can easily evaluate its condition rather than simply covering it up with fiberglass. Besides, I'd bet that 99% of the fiberglass-covered rudders out there more than a few years old leak and are waterlogged anyways, despite what their owners may claim.
