I personally haven't had much luck with any of the hardware store
variety of paints as far as rustproofing goes. What works better is
cold galvanizing spray (zinc spray). You should be able to find it at
good industrial supply or marine supply--sometimes a good hardware store
will carry it. I have used the CRC brand with excellent results on
steel around saltwater.
A two part industrial epoxy coating (not paint) will give even better
results. One such product is Ameron Protective Coatings Corp.'s
Amerlock-400. It is available in a number of colors and can be rolled
or brushed on. This stuff (and other similar brands) needs to be
handled with care though. You definitely don't want to breath the
fumes. Hardware stores don't carry it--you have to get it from an
industrial supply.
