Got a rusty keel and I'm looking for something for the primer and antifoul to cling to. Last year I used primocon but by the end of the season the rust had pushed its way through and the keel had quite badly fouled.

I'm not up for sandblasting.

Has anyone tried any of the following;
Flag Rust Convertor
Fertan
Rustbuster FE-123
and what comments would you make.

I've heard that Hammerite is not up to the task but if you know any other products that you think might be usefull, I'd be pleased to hear.
 
Sandblasting to remove all the rust is the real solution!

I have found Fertan effective on rusty bits of cars but only if repeatedly reapplied until all the rust is "converted"

I might feel inclined to give Jenoseel a try, maybe after treatment with Jenolite but definitely after removing all built up layers of rust by chipping and scraping

I have used Fertan with good effect. On my old boat I used to wire brush off rust patches back to bare metal, apply Fertan, then patch prime with several coats of Primacon. Every year the rust patches became less and less.

The keel in the Jouster is held in by 12 stainless steel bolts with a 3' x 8" mild steel backing plate inside the hull. I spent a while trying to rust protect the thing. The first attempt was with Fertan + paint. It was covered with rust within weeks. Second attempt: wire brush, Finnegans Number One primer, Hammerite and Danboline. Still going strong, 21 years later.

On that basis I wouldn't touch Fertan, but would use No 1 again. It's getting harder to find, though, so I might look at some of the POR-15 products instead.
 
I have the same problem on my Mirage 28. There have been endless threads on this - all with slightly different recommendations. Last year I wire brushed (by hand) primed with Hammerite No 1 primer (lovely shade of pink) and anti fouled over the top. This has improved things but still have some rust. This year I am going to wire brush with brush in angle grinder, apply Fertan, 2 coats Primocon, 2 coats anti foul. I know that success with paint systems lies in preparation of substrate but am not up for sand blasting. I'll no doubt be trying something else next year but will see how it goes.
 
I have a couple of spots to fix and I'm going to wire brush, wash out with fresh water, clean up, dry out and then paint over with epoxy glue. I tried rust converter on a previous yacht, failed miserably.
 
Bring to shiny with an anglegrinder and treat immediately with a rustproofer (Vactan is good and cheap too through an ebay store). Follow with an underwater primer and then antifoul. My rusty keel now only has a very few small spots each year.

Have you got good anodes?
 
Vactan

I'm with Moodysabre, vactan is the mutts nuts. Do a small patch at a time and paint the first coat on while the metal is still bright, I paint over a couple of times for good measure. We use it on board the ships too where the Phillipino's preparation is not the best.

I have some Fe123 but its been too cold to apply it. I also have their epoxy which I was told by them can be used with prior need to treat with the Fe123.

Amaranth's 30year old hull and superstucture are of steel so there will be ample opportunity to test both in the spring!
I also intend to spray the inaccessible internal areas with mil spec Dinitrol.

I would suggest trying their epoxy - possibly 2 or 3 coats and it can be overpainted with anything.
