The one on the door in our 19 was really distorted. I discovered that one end didn't fit properly into the channel on the back side of the door, and it got glued/caulked in that way. I brought it home, removed the mirror, re-attached it with a clear LocTite caulk and clamped it until dry. It's still not like a glass mirror, but it's much better. The entire time I was doing this, I was seriously considering just attaching a thin piece of oak plywood in it's place. We both would have preferred that originally, had we known what the mirror is like.
