These days it's very VERY hard to tell what's what. China sells "leather" bags that are entirely plastic except for a slice of animal skin on top so thin it rivals the real gold plating on some of their gold-plated bling items. They get away with the "leather" label somehow, in a time when all the "unnecessary" consumer protection agencies have been eliminated. I got a Samsonite 100% leather briefcase that was the same Chinese fraud.
The point is that Tesla's seats are no less leather than > 90% of the "100% leather" out there. As a case of Achilles and the tortoise, the ever diminishing layer of leather ultimately can come in a spray. Turtle Wax ICE interior spray smells like a gambling town's morgue, maybe that's the idea.
Someone made the following insightful comment on the subject of wood: you can't "nourish" wood, it's already dead. Same thing with leather. Lexol is actually microdroplets of petroleum oil. I tried several car interior products that were much like that too. Feh.
303 at least doesn't goop or oil the surfaces. No idea what its real merit is - any credible UV protection testing results? At least it's inoffensive. I ended up using ONR, like on the outside paint. One good plastic to another.
