sometimes, when i see pics of silver cars and black black wheels, like the one you posted of the one next to the mustang... it looks like the car is just floating, only showing the outline of that silver car. you know? And which beautiful wheels such as the VMR you wanna show that baby!
I think everyone already suggests the GMetal, just do it dude! or try it with plastidip and clear coat. safest way to see if you like.
Wish you the best outcome OP!
