Painting interior

Ive seen many member/ builds where they paint their interior including seats etc... what paint is used to do so? and if i have black leather would i be able to paint over them??

I don't know about seats, but I've seen a lot of guys on other forums using PlastiDip on interior plastic panels. You can even paint your entire car with this stuff. They just don't have a lot of colors to choose from

If the plastic panels are new, it's best to fire treat it (run a flame over it) there's a uv protection on it. Light sanding with a 3m green pad, then use a bulldog promotion on it then a good primer and use a flex paint and then clear..
