Had a somewhat disturbing observation today. Being bright and sunny (but cold) I decided to take my car through a touchless car wash and I remembered the last time I did that I thought I had a draft from the triangle window area as I went through the blowers. So when my attention focused on that area, I noticed a white frosty looking substance creeping up the triangle window from the rubber seal at the bottom. Not much. About 1/8" or so across the bottom of the glass. At first I thought it was just frost being so cold and all, but when I ran my finger across it, it was gritty and sand-like.
It can only be one of two things: Road salt that has gotten inside the door panels or (and this is what I fear) it is corroding aluminum. It's way too cold outside for me to futz around trying to pull the door panel off and find out.
A second observation, more relevant to this thread, is that I noticed a draft through the door panel at the triangle window are both when the high pressure rinse sprayer went by and also as I passed by the air blowers.
@mknox,
I'm thinking this might be the corrosion from the aluminum frame of the car. I had my car hit this weekend (thread), and the mirror broke off and I was able to take a picture of the underlying aluminum frame and it's all corroded. Here's a picture:
Looks pretty bad to me, don't know if that's normal or not...
