Surface rust question?

[LanceL]

Surface rust question from a newbie with bodywork. I have always had late model mustangs so no surface rust on them. I am doing a 69 Nova with surface rust inside the car on the roof and some rust on the metal panels inside, but it's just surface rust. My question is do I strip it down to bare metal or put a rust type inhibitor on the rust or what? Not sure how much work to do to it trying to get it off? Going to be a street/drag car.
