I have what may be a unique problem. A few years ago I noticed that the paint on my right rearview mirror casing was rippling, but I got it fixed. I'd had the car in the shop after an accident, and I thought that the guys at the body shop had something to do with it, because it looked fine when I brought it in. Anyway, I took it back and had the body shop repaint it. Now the paint has rippled again, and not only that, the casing itself is loose! I've never had this problem with the left rearview mirror casing. What could be causing this to happen?
