Thank you!
The wheels are powder coated with satin black which offers just a touch more sheen than the matte black. I did my BMW boxer wheels in gloss a few years ago and regretted it, prompting me to have them redone the same as these, in satin.
The gloss were initially beautiful, however, the slightest bit of wiping to clean off brake dust, even using microfiber cloth resulted in very faint yet extremely bothersome micro-scratching.
The exhaust was done in Cerakote Glacier Black which can withstand temperature up to 2k (f). The color match is absolutely spot on with the wheels.
I've added a couple of other niceties to not only quench my OCD nitpickery - but, also as functional yet visually appealing enhancements. I'll post up photos in the next couple of days.
