I own a 2017 RM Classic, so, lots of leather. I have been thinking about how best to treat and preserve this leather, aside from what the vendor is saying. I have come to the conclusion that the surface we are treating is not leather but a plastic sealer of sorts. I found this video on the Net and it sort of reinforces my thoughts.So, I still wonder how to handle my leather bags. We are really not treating leather with topical agents but trying to put a patina on a plastic protective cover. So, all the stuff about giving it Vvtamin B and lanolin seems like BS. What do you'all think?
