Did POR 15 come out with a new and improved product? 
Best to remove as much rust as possible before Painting Over the Rust.

Can’t paint over naval jelly. If the jelly even works.
Naval Jelly is nothing more than phosphoric acid in gel form..
I have used it on a large metal box that was rusty to turn the rust black,and I just rinsed it off with water (garden hose) ,let it dry in the hot sun,and painted it with black Rustoleum--it hasn't peeled or rusted since,so I'd say you can paint over it after a good rinse..
P-O-R stands for "paint over rust",it actually needs some rust to activate it and get the best results..many guys I know who tried it said it sucked and was too costly,had sandblasted the parts clean first..
I have used it on several vehicles and all I did was wire brush off the loose rust & crud with a drill,and brushed the P-O-R right over the still surface rusty metal and ten years later it still looks good..
Permatex/Locktite makes "Extend" and Rustoleum has "Rust Reformer" that is a milky looking latex product that dries fairly clear after it converts rust to a black primer,that stuff can be painted over ,and I didn't even rinse it first..
