I had this problem from Day 1 with my SJ200. Small lift, you couldn't slip a credit card under - at the tip of the curve around 5 o'clock as your looking at it. I tried a thin piece of dbl sided tape generously mailed to me by a former forum member. It wasn't strong enough, although I weighted it down with a couple of books for a couple of days. I am assuming the pg has a natural, built in curl. Shortly thereafter, I stopped noticing it, or thinking about it. Hope yours isn't so big that - as you said - you could catch a shirt sleeve on it. I was reluctant to try to peel up a portion to get some glue in there, not wanting to worsen the lift. And, while certainly a matter of individual taste - I would never permanently remove the iconic p'guard. G'Luck.
