Question about leather conditioner
I'm looking at getting into bag restoration as a hobby. Nearly every tutorial I read or video I watch of anything to do with old leather being restored starts with leather conditioner. Well, after deep cleaning...
My question is how leather conditioner actually manages to do anything when most leather is painted. I'm whether it be thinking sofas, bags, car upholstery, whatever. They're all leather with a coating of paint. So how does the conditioner actually get to the leather face to do anything when it has a layer of paint acting like a barrier?
