I took my son for a haircut this morning and while I was sitting in the car, I happened to glance over at my Topaz Stam. The sun's really bright today and it hit the backside just perfect enough for me to see a small brownish-yellowish mark on the rim of the bag right at the base of the kisslock. Upon closer inspection, I noticed what looks like rust at the base of one of the kisslocks on the backside!!! It looks like some of it ran down onto the leather trim on the bag (which is the mark I first noticed). Now, I just starting using this bag this week and purposely waited until all the snowstorms/blizzards had passed. I may have used it once in a light snowfall, but it certainly wasn't exposed to the elements for any great length of time. Has anyone else ever had this happen??? I'll try to take a pic of it - I'd have to use my camera w/o the flash & take it outside (my camera w/flash does not take good closeups). You can't even really see it in natural light. Once I got back in the house, I looked at can barely notice the mark on the leather but I can see it at the base of the kisslock (this is probably why I missed it when I first got it).
