During years I've learned a lot from this forum. Now I have new questions regarding the keel
of my boat.
First question is about the keel
not being level with the hull
as if it was hit to rocks and got separated from the hull
but this would cause some cracks, at least on the gelcoat
but there are no cracks anywhere. Hull is in perfect condition. The keel to hull joint was laminated with fiberglass
to keep it dry but it actually caused a bigger problem. Water
found its way through the poorly made lamination and kept the keel wet even on the hard
causing lots of rust. So, can the cause of keel not being level with the hull be a thick rust layer that tries to separate the keel from the hull?
The keel bolts
seem fine from the inside the boat but very very rusty from the outside. Do I need to change them?
I know this is a millionth time someone asks how to clean the rust but a new opinion might make my day so I ask it anyway. I'm thinking of using an angle grinder sometimes with disks and sometimes with wire brush cup to clean the rust until bare metal. Sandblasting seems to be a very expensive deal even though it surely is the best option in my case. Do you suggest dropping the keel to get rid of the rust thoroughly or is it enough to clean from the outside and put 4 to 6 layers of epoxy
I also am planning to apply phosphoric acid before the barrier coat to eliminate rust returning fast.
Any idea is highly appreciated. Any pics if available would be wonderful if anyone has done this before and took pics during the process.
