I like Tnemec Paints, too, but I especially like saying their name.
I also like Ameron Paints. We used Ameron epoxy under their
polyurethane 15 years ago on the Michigan State Capitol galvanized steel
dome, and the paint is still in excellent condition. Vertical Access
did an inspection last fall, and with only minor rusting at chaffing
joints, we all agreed it has at least another 5 good years. The cost of
access is so prohibitive, we need to monitor conditions, but not repaint
until it's worth the cost of doing the entire project.
Tnemec has been used to repaint the restored metal windows at
Fallingwater, a wet environment, but no salt.

I have used several Tnemec paints over the years. I was most impressed
with Tnemezinc used as a primer to freshly blasted cast iron. These are
industrial grade paints... used on water towers and in harsh
environments. There are several categories of blast cleaning... pay
attention to them. It is not worthwhile to use Cadillac paint on a VW
prep job. ALso, if you are blasting to clean metal pay attention to the
lead content of the existing primer. Tnemec paints are more expensive
than most available paints and not exactly what one would spec for the
run-of-the-mill cast iron facade. For the lower end I go w/ a
Sherwin-Williams (or equal) alkyd -- this for those clients who do not
want museum quality and wherein the driving motivation is to be
affordable enough in the coating that the work actually gets done and
the facade preserved. I say this having done the dastardly deed of
painting at least a dozen cast iron facades. Tnemezinc is by all
reasonable expectations not reversible... but then again it will outlast
any of us. I also recommend that you had better make sure the painters
are experienced with application of epoxy coatings.

I agree with Ken completely. As with any paint work, proper prep and
protection from lead is the most important. We spec Tnemec and
equivalent Carboline coating systems. There aren't many other equals
that I know of.
However, being that I work in NYC "I" think the cost of material is far
outstripped (get the pun?) by labor costs. I still hear gripes from some
contractors but when you do the math material cost is small. Lifespan of
a good paint job using good materials is significant. I like Tnemezinc,
epoxy
135 "2 Typoxy 27 (for lower temperature) and top coats of their urethane
73.
