Since I think the color scheme on the interior of my car was horrid (car body is dark green, dash is black with faux wood around climate and stereo, but a light tan ceiling, seats, side paneling on doors and back)

Does anyone know what would be good to dye normal interior upholstery and side paneling?

I'm looking to make it either black like the dash, or green like the body.

 

Your best bet would be to talk to an upholstry shop. They will have the proper paint/dies, and proceduresto change the color and have longevity as well.
