I must say it does look super slick on the black 6 as it blends in with the color of the car. However, I just had the same thing done with 3M Gloss Black on my Red Mazda 6.Looks great on a black 6, but not sure if it would look quite as slick on any other color.
I however, spayed my chrome emblems with clear plasti dip which turns it into a matte/aluminium finish.
I love it!!
