Ospho is good stuff. Yes, you can use the PPG over the top. Ospho will increase the adhering ability of the paint and it protects the metal from rust as well. Just make sure to use a good prep cleaner to remove any powdery residue. Go easy with a Scotch pad or you may remove the zinc coating Ospho leaves behind.
