If you have flaking rust, the paint will only hold the moisture in causing it to rust quicker.
Whenever you get road salt on your rig be sure to rinse off the radiator.
I would do what we did on the farm with our old equipment, and that is just run a soft wire brush straight down on the fins. Then it's just a matter of keeping it clean and dry the best you can.

On second thought maybe spray some silicone with rust retarded while using the brush.
Only spray it on the rusted areas as the silicone will collect dust. Need to rinse off the collected dust after use for a little while as the silicone wears off and no longer collects it.
