Getting Rid of Rust
attached is a picture of the surface rust under the driver's seat.
Use it to coat rusty frames, floor pans, farm equipment, marine equipment, or even a heavily corroded battery tray.
POR-15® is sensitive to UV light (sun) and must be topcoated for prolonged exposure to sunlight.
Topcoating is not required for areas not exposed to sunlight."

Why POR15 the inside of a vehicle? Doesn't make sense.
Any rattle can will stop the rust in that location. You just need to recover it with paint and you will be fine.
My damn GM battery did the + terminal ****-off all around the battery area-after I got all the acid off I used the POR and repainted-been over two years and its virtually impossible to see where any damage occured.
