We have bolted-on cast iron -- not my favorite material, but what we
have.

That reminds me, Jere--thanks for the suggestion of putting Interprotect on
my boat's iron keel. Preparation was a bit of effort, but now touching it up
for the season is a job of just a few minutes. A great relief.

Hopefully, I also suggested and you used POR-15 first. After 15
seasons, our Interprotect is beginning to fail and I had to spend a day
on the keel. Maybe will blast and re-do Xan this winter.

I don't recall whether or not you did, but I just ground all the rust off
and used Interprotects's primer wash before applying the barrier coat. Seems
to be holding up pretty well.

Well, you'll probably have a good decade before you have to do it again.

Barrier coats *slow* water and dissolved oxygen down, but nothing stops them.

Next time, I'll bang the big flakes off, leaving light rust, then do
the Zinc-something wash to convert the rust and provide a good POR
bond. Fill, fair, then probably whatever the best barrier coat is at
the time.
