Calling all KEEL DOCTORS

[cat25me]

hello from the gulf of maine, south portland, ME.

i purchased a 1978 catalina 25 fixed keel last year with the knowledge i had to make some keel repairs this spring. the previous owner was vague about the keel cracks; there does not appear to be any significant keel angle or keel bolt issue. i believe the keel to be iron based on the exposed rust. i had planned to grind off any loose material, inject 5200 in some of the smallest cracks, fill in with a "marine epoxy or filler"; prime the keel and bottom paint. i would greatly appreciate input as to plan and materials [brands] and what "at all costs" not to do.
thanks; kaptain pete f.

I know you already have seen the answers in the other thread on this topic, but for future reference here's a link to the related topic.

As said before, your first step in any instance like this is to remove nearby paint and grind back the damaged area until you reach sound material in all areas. Only then can you determine exactly what you need to do to effect the repair.

When you get to this point, please post an update, and the way forward may seem more clear.
