    paint them before you undercoat. epoxy primer will seal, but etch does not. etch prime is great stuff, but like regular primer is a sponge, and will absorb water, putting undercoating over it will just trap moisture and actually cause rust. even rustoleum is fine to seal the etch. just a note - don't put epoxy over etch, it will peel off in a week or two...

    Thanks Mark. I learned something new today. I have about as many years as you in the field (40) and never knew not to spray epoxy over etching primer. I have never done it and will now make a mental note not to ever do it. Nice to learn something new without having to find out the hard way.
