You are trying to remove layers of paint and maybe filler to reveal the original paint. That is gonna be tough. To get filler to stick, a coarse sandpaper or grinding disc should have been used.
Unless the current paint job is a rattle can special and no filler, your not going to have perfect original paint under there. The polished patina look is popular, so a coarse cutting compound and then polish will give an interesting result.
Using any sandpaper over 1000 grit will let you slowly cut through the paint, but the metal will have highs and lows, so will the paint...leaving anything from raw metal to the current paint job as the final result.

Heh, I saw the previous 400 and started an experiment.
I blew away almost all of the rattle can primer with the power washer and Super Clean last summer. What's left is some thick, chalky stuff and bondo.
For my test I got out my step and brought it inside where it's nice and warm. The players are this semi-painted step and some 400 grit Durablock sandpaper that plugged up too fast to make me happy. Felt I was wasting it.
Here's my target area.
And after about 5 minutes of gentle sanding and wiping
And after 25 minutes...The long blue rib in the middle by the screw hole and the one below that is where I sanded.
The sanding went ok. It's tedious in the cracks and I obviously got through the primer and into the metal in a few corners. Some places had no blue or black at all, they just went from gray primer to rust to metal.
Looking at my progress I think it would take 3 hours or so to do the whole step.
