Unless you're doing track days, as even with 'spirited' driving the hubs don't get that hot, you can get away with this; remove all traces of scale/rust/paint etc, coat with halfords (or similar) VHT paint, thin layers-colour of your choice, when dried apply moderate heat-pop in the oven or use hot air gun so as to cure the paint, then for a more durable finish apply a coat of acrylic paint. Yes, ordinary rattle can paint
I've used this technique on the hubs of my 350 and more recently my 370, as well as numerous other cars and plenty of bike engine casings etc. With the 350/370 I've used satin black acrylic as I've fitted black 20mm spacers and this just continues the theme
