Facing a similar project a couple of years ago, I asked in the paint
department of a building supply supermarket and they immediately
whipped out a primer product made especially for the job.  This  
eliminates the old practice of etching with a dilute acid, etc.  The
product worked great, stuck a good latex paint to brand-new (washed
with detergent) galvanized metal.  I was surprised to note that a
primary ingredient of the primer was portland cement powder!
