I did mine with some Halfords self etching primer and black hammerite and they came up good. Let some air out of the tires and hopefully you can wedge some cardboard between the tyre and the wheel to protect the tyres (admittedly I did this with the wheels off)
I can't find the original YouTube video that inspired me but not dissimilar to this
but with a lot less sanding/buffing
