Your right about that Joe, Many years ago, I was restoring a full body frame from a 67 Chevelle sedan(2 door post) for some sections I could not get to with the disks and I had to sand blast.
I then treated the frame with a solution from an autobody supplyer-a type of rust mort that had phosfuric acid in it but had to rinse it right away before it was sealed.
Also worked in a machining plant that made couplings for the oil rig pipe tubbing and cassing after they were made, they were phosphated .
Also worked in a plant that coated big inch pipe for the pipe line companies and before the pipe was coated, it would run through a wheelabraider that blasted the pipe with steel particles called shot. It was very easy to get mad working at it or near it when the seals were bad cause shot would fly out of it and it was like getting repeatedly hit over and over with a bb gun.
