ATS Cup Cleaning - De-Polishing!!!

Hi folks,

I managed to get a hold of a set of ATS cups, not in bad nick… Just need a bit of a spruce up.




So, I decided to buy a set of polishing discs and compound and attempt to 'shine' them up a bit.
I got a bit carried away and had a go at polishing the spokes.
I'm relatively happy with the outer rim but not so happy with spoke area and much prefer the central area with a flat finish…
Is there a way I can dull the central part of the wheel back down again to look like the above photo…?

try fine wet and dry 2000 grit plenty of soapy water they will dull down a bit
