Looking for something to stop the rust until the body can be >properly repaired and painted. I have a couple of good early rear fenders for my 71 Fasty project that I have stripped to bare metal. I did this 2 years ago or so. I used a product called "The Must for Rust" to treat the minor surface rust and the bare metal. This is basically a mild phosphoric acid. I sprayed it on adn then worked the rusted areas with steel wool. The acid converts the rust to a black, non-corrosive oxide. I have these fenders in the rafters of my uninsulated garage here in MI (hot humid summers). To date they have not rusted at all. They are the same light grey/silver bare metal as when I put them up there. Phosphoric acid etch is a a pretty common treatment for light rust before body work. I don't think it would work to just acid etch it and then leave it unprotected if the panels are still on the car, however. HTH.
