Something just hit me! The seatbelt in my car! It comes right across my lap at the pocket line there, and naturally the SC60w too! I bet that's contributing greatly to wear on this thing. Just noticed it today. Hit me like a ton of bricks! lol And in response to EnduringEagle, this is the only SC60w I carry right now. The others I have are still new in box. I like the SC60w so much, I bought the others to have in case this one ever quits working, which I actually kinda doubt! Love the warm tints from Zebra, and really grew fond of this little guy. It goes in and out of my pocket many times, being used for a few seconds, or a few minutes at a time. It just makes sense now that the added pressure from the seatbelt, and the light inside the pocket, that the cloth is very slowly abrading the aluminum at those few points you can see in the pictures. Yes, makes perfect sense now. I really found it hard to believe when I first started seeing the wear, that just carrying it like I do, and removing/reinstalling it in the pocket would do it. But as much time as I spend driving, and looking at the whole picture, I think the mystery is over for me now. And I have no doubt, that if I replaced my current SC60w with a brand new one, it would look exactly like this one after awhile. That's a lot of added pressure when I'm sitting with my seatbelt on, adjusting my position frequently. When I leave my house to start my work rotation, it's 3.5 hours min, before I take off my seatbelt and get out of the car in Gettysburg. Done it many, many, times. At least it all sure makes sense to me now, as far as the wear on my light goes. Ok, done babbling now. Take care folks!
