I remember using a bucktfull of muriatic acid (concrete cleaner) to de rust steel pipe. I made the mistake of leaving the bucket in the workshop, uncovered, when I went away to work for five weeks. When I got back every piece of raw metal in the workshop had grown a layer of rust…..Acid is a strange thing, if you submerge metal in it will remove the rust. But if you have an acidic atmosphere due to unwashed acid it will ACCELERATE rusting at an alarming speed! Unless you're able to remove a part, and submerge it in neutraliser and wash, I wouldn't use acid.
I did my trooper using a needle gun and MBX tool to remove loose rust, and then thick Dinitrol. It's lasted a few years already.
Jotun or paint is only useful if you can get back to clean metal. It won't grip otherwise and the rust will spread under the paint.
