rust inhibitor

[greendayhbt26]

i am repainting some areas that have surface rust on my 98m s-10. i was just wondering..in some areas i cant sand the rust out too well because its a tight space so if i use rust inhibitor primer will it stop that little bit of ust from coming throught the paint.

any help would be appreciated as well as any tips or tricks on doing what im doing...

thanks

use acid in the areas you cant reach then use amonia to nuetralize it dry it off with a air nozzle then rust inhibit it.
