Hi All, The proprietary preparations are usually based on ortho-phosphoric acid in a jel matrix. It turns the iron oxide to iron phosphate which is black. Yes, you can paint over it but beware, if you don't dry it thoroughly the rust just starts up again, breaks out of the paint layer and there it goes again. I have early experiences of owning old (sorry, Classic) cars and fighting a never ending battle with rust. I rebuilt my Frogeye Sprite twice because I didn't get it right first time, mind you, having an argument with a Ford Escort didn't help.
