I know both windshield and rear glass seals suck. They leaked when I pressure washed the car. I dont think those seals are too expensive - but that is something I would leave to the pro's. Its lower on the list than many other tasks I have.

BTW - I checked the drains under the hood hinges. They were junked up with debris. The sunroof doesn't open or I'd check those.

Im not looking to pull the seats out either - maybe if only for a few minutes.

I'll see what I can do with the sound barrier. But I'm not sure I want that removed either - the car is plenty loud as it is.
