Interesting post.

Are the 124 mirrors glass with a coating?

I am wondering because mine have these spots all over them and I am hoping that I could use Plastic-X to polish them out.

The mirrors on my '87 and one of the mirrors that I got from P&P also were badly water spotted. AFAIK, M-B mirrors are not AR-coated so you don't have to worry about damaging anything. However, the water spots are a build-up of calcium salts and other hard-water nasties and something like "Plastic-X" might not be strong enough.

The old standby is vinegar. I have used Lime-away with fair results. If you remove the mirrors, you can lay them in a puddle of Lime-away and leave them for 24-48 hours. With the mirrors on the car, you have to hold a soaked sponge to the mirrors, which is harder to do and then the stuff drains out the bottom.

For a final removal of the stubborn bits in the corners, I used Rutland's "White Off." Made in Rutland, VT, the stuff is designed for cleaning the glass-ceramic windows in wood stoves. I recommend it. Available from places that sell wood stoves, gas fireplace inserts, etc. Florida residents can email info@rutland.com.
