When I'm finished I will have black seats and other leather trim bits and a re-dyed shadow gray on the rest of the panels. The Gray will be a shade or two darker than it is right now but not straight black. I like the contrast. ALL carpet inside, including the carpet along the bottom of the door cards will be professionally re-dyed black as well. I have no idea about the process. All I know is I hand them my goods and some money and a few days later I pick my goods up in like new shape with the requested changes made
