I noticed something recently with my mirrors, that I hadn't noticed in the previous 8000 miles I've done, and wondering if it's something I've done or missed, either when I stripped them to have them Gloss Blacked, or the amount of wax I put on my van! Anyway, they seem to be constantly soaking wet when it's raining. That might sound a bit daft, but as I drive I can see the water tracking under the mirror, then flicking across the glass, meaning they constantly need wiping to be able to actually use them.
The picture below was yesterday after about 50 miles, and although it might look like you can see, in reality they are quite obscured.
