It's impossible to know. One of my PMs didn't peel until it was almost 3 years old. It's a design flaw the way the strap clips rub against the flap edges from body movement. The bags were perfectly made. I'm on my 3rd one, this time in empreinte. I've heard that these can have glazing issues, too, but I love the design of the bag. I would recommend getting a PM anyway. You can always bring it back to LV if you have a problem. It's a great, functional bag.
From my own experience the clasp rubbing on the glazing on the flap kinda only really happened when I wore it crossbody whereby the bag was placed near to my back. My 1st PM suffered glazing problems it was my 1st ever LV bag. With my 2nd PM which I've had a year now. I rarely wear it crossbody, just shoulder carry, its been fine so far. To be honest If I can get 3 years without glazing wear I'm happy. I like the bag a lot but realise that it comes with compromises and risk. I feel I can now deal and tolerate them when that time comes because I've had a bit more experience with how LV works now than I did before.
It might be only me., and the way i walk, but when I have the bag crossbody, bag towards my back the bag bounces on my back more with how I walk hence more side to side movement with the straps so the clasp rubs onto the flap. It probably just me walking funny.Interesting. I carry mine crossbody and pushed back.
