Re: O'day Tempest keel / hull joint
I didn't work on the boat at all last year but got back on it this year.
This past weekend I finished the keel joint repair and thought I'd list out the steps I took here in case someone else goes about the same challenge:
There was a shoddy repair of this joint that seemed to retain water better than a camel.
The repair consisted of the use of 5200 in the joint, encased with a very light fairing compound on top of bottom paint on both the hull and the keel. That was surrounded by a couple of wraps of fiber cloth with epoxy, more light faring compound, an thick barrier coat topped off with VC17.
My repair consisted of:
1) Grinding out the old repair. (I chipped all the 5200 I could get to, I figured if I couldn't get it out after 3 days then Neptune intended for it to stay.)
2) Removing all bottom paint.
3) Sandblasting the keel.
4) Wetting out the join with epoxy and putting a coat of epoxy on the entire keel.
5) Using 406 filler with epoxy and filling the joint.
6) Applying 4 more coats of epoxy on the keel.
7) Using 407 filler with expxy as a faring compound. << This is the step I am at right at this moment.
I plan on adding a couple of coats on any area that seems to have a thing gel coat or where I may have sanded through.
I then will fair the keel and the hull smooth.
And finally apply Interprotect as a barrier coat and apply VC17m.
How does that plan and repair sound?
