I used duplicolor silver, and it tuned out to actaully be duct tape grey. Less brigt, but not as dark as the charcoal. I am in the process of redoing them... I am considering the chrome also, it doesn't actually look like chrome, I used it on the inside of my taillight housings, and it is silverish, but brighter than argent. Think twice about the duplicolor, my experience sucked with that type of argent color. I need to buy a couple more NEW cans, and see if I just got a few old ones at the store when I did it.
