I would definitely use a rust converter. Not the typical stuff though. Find OSPHO. It is generally be sold in Marine supply stores. You can find it online. It will convert the rust to a very deep level. Make sure you get all the powder residue off the converted rust before you apply zinc chromate epoxy over the rust.
