I was reading an article on a truck restoration and the guy used rust converter inside the fuel tank after knocking off the loose stuff with some nuts and bolts and shaking. After a bit of a search it seems like a few people have done this on car tanks.
Anybody ever hear of this?
last week
This stuff does not remove rust, but chemically changes it and turns it black.
I used some of the rust converter on a rusty patch on a car body and it seemed to leave a coating that was sandable and reminded me of linseed oil or Tung oil on wood. It was a kind of milky looking sheen but felt hard. The rust turned black. I don't know if this just appears to be a coating or if there is a layer of something left over the rust?
If there is a residue is it fuel proof?

it is. but id still coat it.
. Ive seen it work, then rust again from the bottom under the converted layer. it actually turns it into an iron tannate. But doesn't nec remove it. I remember using this stuff from way back in the 90s on cars. I prefer the rust removers, like the evap o rust, metal rescue, or just phosphoric acid. it removes the risk of any deeper rust being trapped under the black layer the rust converters create.
