Need help painting my interior…

I have heard a lot of mixed opinions on this. Some say it works, others swear it doesn't. I tried to search it, but came up short.
I need to paint my entire interior from dirt brown to black, the metal will be easy enough, but the plastic and vinyl may be tricky, any tips on products or procedures? Also, the previous owner replaced the headliner(brand new cloth...brown), does anyone know of a product to paint or dye this as well, or the best way to attempt it.
Any help is greatly appreciated.
