Flex Seal doesn't work cause it's dripping and doesn't hold well when filling vertical lines. I used this one instead and it seems to work so far:

Yeah I tried the flex seal and made a mess everywhere. Plus it was still leaking

I used clear silicon and put a bead along the top seam. There was a rubber/plastic piece between the glass and metal, I ran the bead just behind that rubber/plastic piece. No leak in over a year now.

Nilao, I think you have the cure for my leak. I opened everything up, replaced the foam with butyl rubber and it still leaked. I believe my leak wasn't so much behind everything, but was leaking where the glass itself is supposed to seal against that rubber trim.

CAUTION to anyone doing this: I may have bent the window open too far while trying to fix it and now it leaks worse.

I did this fix last summer on both windows that were leaking like crazy, only took me a couple hours per side with a single bunk truck. Make sure you layed the butyl rubber thick enough that it seals properly. It even sealed at the top where I had to cut two of the bolts. Only butyl is holding it there and I havent had one drop since... knock on wood.
