Re: Streaking...
I have had instances where if it's very humid, I might go a few days and still bring streaks up, but that is extremely rare.
When the windows are down, take a look at the seals, maybe post some pictures. I imagine they might be wearing out as geeroy suggested. Maybe you just have dirt caked in there that's not coming out with regular washing. Some of the mud/crap sticks like glue!
