Broan 684 bathroom fan - Galvanized? NOT!

 I just ordered a replacement 97006987G motor bracket, fan and assembly
for my 23 year old Broan model 684 bathroom fan.  The old one was
painted steel, and turned to a bucket of rust.

The specification sheet at the Broan web site states that the new 684
"housing" is galvanized (I missed that qualifier... I thought it was
all galvanized.)  Not only is the fan bracket not galvanized, but it's
raw freakin' steal with not even a coat of paint.  What garbage.
Don't buy one of these.

I need to give the bracket a good coat of primer and paint that will
resist rust.  A really good primer.  Would 'yall please make some
recommendations about the brand and type of paint and primer I should
use?

I'm looking for something better than Rust-Oleum, and I don't mind
going to an industrial supply house or the internet to get it.

Thanks.

You won't find anything better in a consumer paint product. True, the
dry time is somewhat long, but that's the tradeoff for the proprietary
resins that do the work.
There are so called zinc-rich finishes that approach galvanizing for
corrosion resistance with names like 'Co-Galv' or something like that.
Probably available from Grainger or other industrial supply, and
fairly pricey.
Powder coatings are a mixed bag, because the baked on resin is not
necessarily a rust inhibiting vehicle. Once the coating is breached,
the rust spreads rapidly. For examples, check the pickup truck bumpers
in the WalMart lot. You'll find some ratty looking powder coated
examples there. The thickness of the peeling coating is the sure sign
that it was a powder finish.
If you don't know anybody running a hot dip galvanizing facilty, then
you other choice is a plating shop. Doesn't take much to hang it on a
hook and run it through with other parts while you wait, and the $ may
be less than you think.
Pick your best option and go for it. Good luck.

Hammerite.  Comes in spray cans, designed to go on bare metal so no
primer required.  Masterchem is the manufacturer which I think also
produces Kilz.  An Ace or TrueValue hardware store should have, as do
some big box stores.

Can't suck that much if it lasted 23 years.

How many more years are you going to live there?

How long will it take to rust out again?  Will any other parts break
before that?  I replaced the guts of one of my bathroom fans after 5
years, I'd say your bucket of rust did pretty well for 23.
