OSPHO is just phosphoric acid. It converts iron oxide to iron phosphate. I cannot find it here any more but can find the same stuff in the metal prep section of Home Depot by the gall0on.
I have found that rust will eventually creep back with time if the area is not painted after treatment. I use a spray bottle for app also along with eye protection and hand protection.
