Better late than never, here's the satin black Ionic rear diffuser on my Lakeshore Slate coupe. Just a quick phone snapshot in hazy light, but will give you an idea. The rear mudguards are also from Ionic, painted Lakeshore Slate, since they are out of production by Infiniti. And I've thrown in a pic of the grille for a bonus.

 

thanks for the follow up. looks good, but I am still on the fence. that is why I want to do the vinyl wrap in case I do not like it, plus it is less expensive. your car looks nice and clean with a unique paint color...don't see many Lakeshore Slate.
