I am getting my boat ready for the water
and I want to seal the keel/hull joint on my 1978 Pearson
26. The seam is pretty tight (compared to a lot of other boats in the yard, for example) and there isn't much movement on the keel
. Still, there is a small space around the entire keel
(which is cast iron) and of course there are some rust streaks where the water
got in and out.
I am planning on sealing this seam with 3M 5200 Marine Sealant
, which I'm told is strong and flexible enough to keep the seam closed up for at least a few years. My question is: is there anything I should do before I apply the sealant
? I did some light grinding and used a wire brush to clean it up but I'm wondering if I should do more. I have some POR-15 Rust locking paint
that I am going to be using on the top of the keel bolts
. Is it wise or worthwhile to squeeze some of that in the keel/hull seam as well to stop any further corrosion
on the bolts for example? Should I do anything special to dry the seam before I seal it? Perhaps acetone or a heat lamp?
Any advice you can give me on this rather simple yet important maintenance
would be greatly appreciated.
