Cast Iron Keel Suggestions?

So I'm hauled out and trying to get things done. The keel doesn't really look bad overall. No real blooms that I can see. The seems at the top need a little bit of work is about it.

As far the rest of the keel there are a few spots/pits that look like an old layer or two of previous paint layers came off via regular cleanings/barnacles or during the pressure wash. I'm thinking these just be filled in with a little thickened west system, a light sanding, and then just straight to the bottom paint?

I bought a gallon of Rustlok but I don't really see a need for it yet.

Does anybody feel like there is anything else I should be doing on this? It's my first time doing it all myself and I certainly don't mind asking for opinions.

Re: Cast Iron Keel Suggestions?

My dear Yeti,

Whatever you do, make sure salt water cannot get into the iron ballast. What happens then is hideous, in labor, at least, and if you have someone else rectify it, $$$$!

Good luck with it, looks okay so far.

Ann

Here's a couple pics of the other side. Basically I don't think I'm seeing any big rust issues. So I plan to just fill most of those little pits in the layers it's thickened epoxy and then paint over with the Trinidad.

I hope that I'm reading this correctly....

Re: Cast Iron Keel Suggestions?

On my cast iron keel. I cleaned it then coated it with tar epoxy then bottom paint. That was 15 years ago now I just apply bottom paint at haul outs over the tar epoxy. Tar epoxy is nasty stuff and you do not want to get dust from sanding on you. If I could go back I would leave off the tar epoxy and not worry. It's cast iron so you could just clean it and bottom paint.
This is one job not to over think.

Re: Cast Iron Keel Suggestions?

If I remember correctly one of Don Casey's books recommend to encapsulate the area with epoxy and run a wire brush across everything before the epoxy sets, insuring the epoxy sticks only to good metal and isolates any small rust particles left. After that I added two gallons of interprotect and a couple coats of bottom paint. My Grampian's done fine with that so far (4ish years now)

Re: Cast Iron Keel Suggestions?

if you want to really solve the problem. clean all oxidization from it, epoxy it, glass it from bottom up to the hull and fair it, fix all blisters in the hull and barrier coat the hull and bottom paint. epoxy the bilge too, to prevent water intrusion to the keel from there also. bucks right now but pressure wash and paint from then on. did that to a 27 footer and didn't have a problem for the four years i owned it and the friend that bought it eight years ago still hasn't had a problem.

Coal tar epoxy was great - pity about the environment and our health. Fortunately it is no longer sold in the environmentally aware countries.

Whatever system you use the real key is getting it totally clean to start with. The only way to do that is to hire a grit blaster. It will take ALL the paint and any rust off, should finish up with a fine gray finish that has a good key. Fill any pits with epoxy then use a good underwater metal primer

We just did one with G Flex, grind any rust off, one coat G Flex , then use regular bottom paint for your area.local guys can tell you the best one.

Re: Cast Iron Keel Suggestions?

I just hauled Shadowfax out for complete repaint/repairs.

My cast iron keel scraped bottom once or twice. From side views everything looked okay. However I used a mirror to view the bottom of the modified find keel and found a good amount of rust where it had kissed bottom.
It would have been easy to miss if I hadn't used the mirror.
