The steel tank that has rust is already compromised,  or beginning to be, dependant on how much rust.

From a metallurgy point of view,  steel sheet has been rolled to get it's thickness to required dimension for component pressing.  This makes it effectively close to forged and maintains a compression of the surface that is a little resistant to corrosion because of its physical structure. It's this property that fuel tanks have taken advantage of for years,  so they've never really been treated during production.

If you've left a piece of sheet that's been cut in damp conditions,  the cut edges will very quickly corrode and general surface take much longer.

Once you cut, grind,  corrode etc you loose this refined surface compression,  making it far more likely to flash corrode as you further prepare it.

My tank was rusty inside, I used DEOX-C to clean it before I liberally coated the inside with oil for storage.  ;D

I had good results from (I don't have the pictures to hand). Not expensive, water soluble.
