I used to use it in my family business, for really rusty shelves which would then be covered with machinery enamel. While I had good results with it, we ended up just using a good primer in most applications, since we needed to wire brush them anyway for the Ospho.
I used it with good results to temporarily treat rust on car body panels. It seemed to really slow down the spread of the rust. In most cases I just rattle-can sprayed over it, and the area would look okay for years. I have spots on my race car trailer fenders which started rusting in the salty air of Eastern NC. I wirebrushed them and treated them with Ospho, but never got around to primering or painting. So far the rust has not returned (6 years later, but 4 of those years in Oregon). I may even paint them one of these days!
