Touch up rust spots in black steel speaker stand?

I just bought a used pair of Sound Anchor stands that need a little touch up, too. The paint is a little grayed out so rather than touch up I'm going to clean them and then rattle-can the entire stands with some textured black paint that I got at the hardware store and then they'll look brand new all over. I got the paint to touch up my motorcycle where I ground off the side reflector mounts on the saddlebag frames. The textured paint is very black and looks really good. A lot more work than touch up but they will have a very uniform finish when I'm done.

Before you sand, it may be superficial rust. Have you tried cleaners on the spot. If anything take a small dab of WD40 and that can sometimes lift the rust off while coating the exposed metal and preventing it from rusting. If there is any area left without paint you may be better off to paint the whole stand with a light coat of matching paint.As mentioned above.

Along theo's lines, a dab of rust reformer (various brands, should be at the hardware or auto stores) should do the trick. They make it in spray cans and jars. Get a jar and use a q tip. It turns black, you may not need to top coat it.

I have touched up some minor dings on a black amp with Sharpie marker pens. Same thing with piano black speakers.

I used Naval Jelly on some Target stands that had been stored for several years to remove rust.
