I've got an '02 F150 Supercrew and I noticed the rear seats were wet yesterday; sure enough, the seals along the top of the rear window (a single-pane unit, no sliding window) have separated for about a foot and a half right above where the seats were wet.
What's the best way to go about re-sealing that? What kind of sealant should I use? I'd rather not have to replace the whole window unit at this point.
