Gas tank woes

[JohnEd]

Guys,

I thought that once you screwed up and let a tank get all rusted inside it was shot.  Might I be wrong?  Hope so!

I recently read a blurb on something(product) I was using that had lots of nasty acid in it.  Burried in the label was a statement that the acid was a "rust disolver".  I am soooo old I can't remember what I was using or what it was.  "Say it ain't so, Joe"..... can I pour something nasty in the tank and then flush out the rust with a hose?  That would save a bundle for two 50 gal gas tanks.

Thanks,

John
