There's a couple of sumps at the bottom of the section with black iron grates over them, just cast iron with black paint. Some of the paint has flaked off and the grates are busy rusting away underneath. In terms of addressing this, I was wondering what's best, wire brush + black zinc or rust converter + something. In other words should I remove as much of the rust as possible and start again with black zinc, or try and stabilise it and maybe use black zinc on that?

Best is the CRC oxidising rust converter, then the primer, then top coat. Rustoleum is good at priming and top coating itself. Whether you can be bothered with the extra steps for a grate though...?

 

FWIW, I've had the CRC spray and the paint on stuff. Paint on stuff works way better IME, though obviously is more hassle to apply.

The spray stuff is so convenient, and saved me a ton of time when fixing the roof, but it clogged the nozzle within a couple of minutes of use unless you do the "hold upside down and clear" regularly. I now have a couple of half-empty cans that I can't use, and I'm wondering how to get the contents out so I can use them without an explosion happening...

I've got a bottle of the CRC rust converter so I'll go with that rather than the wire brush approach, definitely prefer paint-on because you have precise control over where it goes and can e.g. dab it into particularly bad areas. Reason for doing it is that some of the grates are in high-ish traffic areas and having rusting blistered grates over the drains doesn't look too good, but rust converter and top coat sounds fine.
