    Not sure if I posted in the right topic.

    I have been goofing off up on the roof of the airport for the last two weeks. But I have to get serious and find some stuff to prime zinc coated sheet metal. There is a very large area that needs to be primed I was wondering if anyone had any ideas.

    Considering that I probably should not wash down the substance into the roof drainage system.

    All these brackets in the link below on three different roofs on both sides and the back, get covered with zinc coated sheet metal. And the sheets have to be treated with something to make the paint stick. I was thinking of the Direct to Metal paint, but I don’t have anything set in stone. I don’t even know if that would be a good idea?

    I think for quality purposes I should work the metal and mount the metal, then paint. Any ideas would be great.

    We are looking into things like vinegar and lemon juice, but even that sounds messy.
