Yep, black satin engine paint on mine, mainly because I had some on the shelf
I've also done the messy area between front hub & disc that MMC leave as untreated casting & it soon corrodes & looks nasty
Ditto plus what parts of stub axle I could reach some time ago, although took the recent opportunity to do a better job with some more Hammerite silk black. When eventually I have to renew kingpins will strip out stub axle and do a proper job.
