The salesman said that Armor-All is not good to use because of the oils it contains or something. He recommended 303 Aerospace Protectant, he gave me a sample and it works pretty good, doesn't leave that layer of oil like Armor-All. I got Lexol at Oreily Auto Parts, it is amazing, I should have taken a picture of what my seat used to look like. It helps to remove creases and cracks by cleaning the dirt that gets buried in them, makes them less noticeable. It also make the leather much softer and plush, feels like you sitting on a cloud.

Be sure to use leather conditioner after and let it sit overnight.
