As I have said many times before, when I was picking up paint for my dump truck body that I was sand blasting, the paint guy at the jobber told me that I needed to acid wash before priming, so I bought a gallon for not a lot of money and used it. At about the same time a professional body shop owner friend took side panels from one of my tractors and prepped and painted them for me as a favor. There were a few pits where a foam insulation strip had rubbed on the metal for years. He had cleaned the panels to bare metal but after three years there were bubbles where the pits had been. None of us want this on our tractors. The same has happened on another tractor in a place where the paint is rubbed every time that the tractor is put in gear. Both were painted by intelligent people who know how to paint but that work mostly on newer cars and not the old rusty stuff that we work on. Just because it appears to be rust free doesn't make it rust free. It depends on how long you want it to last. I got a bottle of the expensive stuff at my local auto parts store probably two years ago and followed the instructions and I could see where here and there it turned black indicating converted rust in places that I thought I had the cast or steel clean. I see that as a very good thing. I also read on the container that it is phosphoric acid, which I knew to be the same as in milk stone remover but for much less money. I use it all the time. I spray it on full strength or dip small parts in a container for ten minutes. I then wash off with plain water. If I don't wash enough I get some white residue, but this comes right off with another application of the acid and a little better rinsing. I may get a little flash rust but the epoxy primer handles that much more easily than rust left to grow in pits. If the air is humid I will wipe it dry after rinsing. Your rusted sheet metal is a situation where the acid is of great benefit, as I am sure that with all the work you are doing that you don't want rust bubbling up out of pits under your paint.
