If you can find any chem. film for aluminum, it will provide a surface for
the primer.  For primers we are using epoxy primer, which also has
chromates in it.  Zinc Chromate is no longer available in much if not all
of the industrial supply places.  The epoxy primer is not expected to be
around much longer.

Strontium chromate primer (two-part) is still available in the US - try marine stores.

I've been using Hammerite on alluminum with excellent results.
I wire brush the alluminum to make it clean and give a rough surface for
the paint to bond to.
It has worked fine for me , but I wouldn't recommend it for underwater use
without some tests.
Hammerite is available at most hardware stores , and has become my
favorite paint for everything.
It can be purchased in either spray or liquid form. It has the highest
percentage of solids of any commercial paint on the market.
For this reason , once you start using a spray can of hammerite you have
to use it up with a week or so or the feed tube inside will get clogged so
bad you have to toss the rest of the can.
I have no idea what hammerite is ( i.e. lacquer, enamel, epoxy, pixy
dust), since they don't tell you on the label, but to clean up the stuff
you will need a pint of the special Hammerite thinner .
I also use it in my Binks, but it really needs a pressure pot. Trying to
spray Hammerite with a sypon gun is like trying to suck molasses through a
straw. You have to thin it down so far to get it to spray that it takes
several coats. Hopefully, soon, I'll get a pressure pot.
Hammerite is unique in that it does not require a primer coat , even over
rusty metals.
 I have found very little that it won't stick to.

Best of luck

Your comments about epoxies jogged my memory: WEST Systems sell a two-part
aluminum primer useful for prep before epoxies or paint.  Hope this helps. - martin
