So my new car arrived yesterday and it has this Vernasca leather the dealer kept telling me about, so its on oyster beige and I'd really like to protect it somehow. These are the suggestions I got: Gtechniq L1 leather guard, Carpro Quartz Leather 2.0. Theres this one other thing but I forgot what its called. Question is, how do they actually protect the leather? And do they have the same purpose?
