Have a look at this pic - the grille surround is the same aluminium paint. You can see the shade is very similar but it's more like a satin effect and not a lacquered shiny finish. I like the contrast of it against the rest of the car.
I used it because the skid plates on other brands of cars aren't a lacquered silver but more like a metal effect paint. Merc ML for example looks alu, Volvo looks chrome, etc. TBH, its very hard to tell the difference it's very subtle.
