Painting Steel Wheels with Hammerite or alternative?

[MC Bodge]

Last summer I re-painted my black steel wheels with one coat of Smooth Hammerite:


I rubbed the wheels down (although I didn't take them entirely back to bare metal), cleaned with brake cleaner, buffed them clean, painted with a brush in the garage, put them out to dry in the sun and left them in the garage for a few days afterwards. The paint appeared to cure well.

I can now see the rust showing through a little.

Do I do the same thing again or is there a better way?

Only about 250 miles, but thanks.

Tyres are on the rims, so more convenient to paint with something. I might just rub them back more vigorously with power tools, use rust preventer and paint with Japlac or similar, as it is less faff than Hammerite.
