I opened up the rear-view mirror again. First did this on 2011-08-29, so at least I knew what to expect. But I still don't have the nerve to "snap" the mirror stem out of its holder under the inside top of the windshield.
Cleaned the 2 interior glass surfaces, then got ambitious and hit the chrome surround piece with polish. Considerable improvement, but still not perfect. I noticed that there is a gasket around the glass, and my gasket is major cracked even though it's not disintegrated. Is this gasket NLA, or can it be replaced?
Putting it back together went well, taking great care to get the little wire holder in properly at the bottom where the black plastic tab swings the mirror for night use.
It being a beautiful day in southern Ontario, then went for a drive. First went past Rolf-Dieter's house to see if we could catch him flat on his back under the Blue Tornado, but there was no sign of him. So we drove down to Port Stanley, which is a quaint little inland harbour and tourist spot, and visited a friend -- who admired our Pagoda, just as we hoped. A fine day.
