POR= Paint Over Rust. It actually more difficult to use POR on bare metal or new metal. As already mentioned you need to brush off the loose rust but you don't need to get it down to bare metal. I don't use their cleaner/degreaser but I do use the metal prep that is supposed to neutralize the existing rust.
Being in Vermont it's a never ending battle for rust prevention, worse now that the state has hopped on the salt brine train. Formulated to stick to the roads means formulated to stick to your vehicle.
