A couple days ago I posted my guess on what the new finish is on the m class, it definitely has the look and feel of Cerakote...I'm now changing that opinion, one of the bottom front corners is beginning to show signs of wear and I can see metal showing through, it's very slight but it's there none the less, so I don't think it's a Cerakote finish, there's no way Cerakote or similar ceramic finish would have worn off in just a couple days, I carry it in an empty pocket, no loose change or anything else has touched it...I highly recommend a silicone sleeve or wrap ASAP.
