vinyl question

'm looking to customize the intrior of my car. I aleady have all the hard plastics colored blue, and I wan't to die the soft vinyl black, does anyone know how I go about doing this? What kind of product would I need to do so. I've died and painted alot of thing, but I want a coor that looks natual. If anyone knows and can help it would be appreciated. If anyone knows of like a website online with a tutorial with pictures, that would be great. Thank you for any help.

my web page has a brief tutorial. But the pics suck...bad! I have completely redone everything. Do a search on painting the dash or duplicolor and you should find what you are looking for.
