Wait, he actually asked for glass he knows won't last? That's wild! That's like asking for a bike with a cracked frame because it's cheaper now. Sure, it might work for a week, but then it fails completely. You're basically helping him buy a giant, expensive problem. The first big storm or temperature swing could shatter it or cause major leaks.

Which store brand was it? I had that exact thing happen with some bargain ones from the big hardware chain, the orange one. The fuzz wasn't just on the surface, it got embedded in the paint layer and sealed in. It's not just about time, it ruins the whole finish permanently if you don't catch it. You have to look for the ones that say "no lint" or feel the sleeve material before you buy, the cheap ones feel like a fluffy towel.
