Hay and alfalfa from ranching in western region will do the same.
It what saved quite a bit of my 51 6400 cab from rust, though...especially when grease and oil gets involved into the mix.
Did have to patch a spot on the rear of the cab from a forgotten truck parts catalog left behind the seat inside years ago.
The original paint on the firewall was very fresh and shiny when degreased.
Funny that it was a parts catalog.
